INTRODUCTION

Marketing is the process of communicating the value of a product or service to customers, for the

purpose of selling the product or service. It is a critical business function for attracting customers.

From a societal point of view, marketing is the link between a society’s material requirements and its

economic patterns of response. Marketing satisfies these needs and wants through exchange processes

and building long term relationships. It is the process of communicating the value of a product or service

through positioning to customers. Marketing can be looked at as an organizational function and a set of

processes for creating, delivering and communicating value to customers, and managing customer

relationships in ways that also benefit the organisation and its shareholders. Marketing is the science of

choosing target markets through market analysis and market segmentation, as well as understanding

consumer buying behavior and providing superior customer value.

There are five competing concepts under which organizations can choose to operate their business; the

production concept, the product concept, the selling concept, the marketing concept, and the holistic

marketing concept. The four components of holistic marketing are relationship marketing, internal

marketing, integrated marketing, and socially responsive marketing. The set of engagements necessary

for successful marketing management includes, capturing marketing insights, connecting with customers,

building strong brands, shaping the market offerings, delivering and communicating value, creating long-

term growth, and developing marketing strategies and plans.

Pharmaceutical marketing, sometimes called medico-marketing or pharma marketing in some

countries, is the business of advertising or otherwise promoting the sale of pharmaceuticals or drugs.

There is some evidence that marketing practices can negatively affect both patients and the health care

profession. Many countries have measures in place to limit advertising by pharmaceutical companies.

Pharmaceutical company spending on marketing far exceeds that spent on research. In Canada, $1.7

billion was spent in 2004 to market drugs to physicians; in the United States, $21 billion was spent in

2002. In 2005 money spent on pharmaceutical marketing in the US was estimated at $29.9 billion with

one estimate as high as $57 billion. When the US numbers are broken down, 56% was free samples, 25%

was detailing of physicians, 12.5% was direct to user advertising, 4% on hospital detailing, and 2% on

journal ads.

The marketing of medication has a long history. The sale of miracle cures, many with little real

potency, has always been common. Marketing of legitimate non-prescription medications, such as pain

relievers or allergy medicine, has also long been practiced, although, until recently, mass marketing of

prescription medications has been rare. It was long believed that since doctors made the selection of

drugs, mass marketing was a waste of resources; specific ads targeting the medical profession were

thought to be cheaper and just as effective. This would involve ads in professional journals and visits by

sales staff to doctor’s offices and hospitals. An important part of these efforts was marketing to medical

students

To health care providers

Marketing to health care providers takes four main forms: gifting, detailing, drug samples, and

sponsoring continuing medical education (CME).Of the 237,000 medical sites representing 680,000

physicians surveyed in SK&A's 2010 Physician Access survey, half said they prefer or require an

appointment to see a rep (up from 38.5% preferring or requiring an appointment in 2008), while 23%

won't see reps at all, according to the survey data. Practices owned by hospitals or health systems are

tougher to get into than private practices, since appointments have to go through headquarters, the survey

found. 13.3% of offices with just one or two doctors won't see reps, compared with a no-see rate of 42%

at offices with 10 or more docs The most accessible physicians for promotional purposes are

3

allergists/immunologists – only 4.2% won't see reps at all – followed by orthopedic specialists (5.1%)

and diabetes specialists (7.6%). Diagnostic radiologists are the most rigid about allowing details – 92.1%

won't see reps – followed by pathologists and neuroradiologists, at 92.1% and 91.8%, respectively.

Edetailing is widely used to reach "no see physicians"; approximately 23% of primary care physicians

and 28% of specialists prefer computer-based edetailing, according to survey findings reported in the

April 25, 2011, edition of American Medical News (AMNews), published by the American Medical

Association (AMA).

New pharma code & guidelines

The Pharmaceutical Research and Manufacturers of America (PhRMA) released updates to its voluntary

Code on Interactions with Healthcare Professionals on July 10. The new guidelines take effect January

2009."

In addition to prohibiting small gifts and reminder items such as pens, notepads, staplers, clipboards, pill

boxes, etc., the revised Code:

1. Prohibits company sales representatives from providing restaurant meals to healthcare

professionals, but allows them to provide occasional meals in healthcare professionals’ offices in

conjunction with informational presentations"

2. Includes new provisions requiring companies to ensure their representatives are sufficiently

trained about applicable laws, regulations, and industry codes of practice and ethics.

3. Provides that each company will state its intentions to abide by the Code and that company CEOs

and compliance officers will certify each year that they have processes in place to comply

4. Includes more detailed standards regarding the independence of continuing medical education.

4

5. Provides additional guidance and restrictions for speaking and consulting arrangements with

healthcare professionals.

However, the Good Works Health government-approved platform offers physicians and other health care

professionals the opportunity to direct donations to charities of their choice in exchange for participation

in pharmaceutical promotional/educational programs.

Free samples

Free samples have been shown to affect physician prescribing behaviour. Physicians with access to free

samples are more likely to prescribe brand name medication over equivalent generic medications. Other

studies found that free samples decreased the likelihood that physicians would follow standard of care

practices.

Receiving pharmaceutical samples does not reduce prescription costs. Even after receiving samples,

sample recipients remain disproportionately burdened by prescription costs.

It is argued that a benefit to free samples is the “try it before you buy it” approach. Free Samples give

immediate access to the medication and the patient can begin treatment right away. Also, it saves time

from going to a pharmacy to get it filled before treatment begins. Since not all medications work for

everyone, and many do not work the same way for each person, free samples allow patients to find which

dose and brand of medication works best before having to spend money on a filled prescription at a

pharmacy.

Sale and techniques of sales

5

To become a successful sales representative you need to have a solid understanding of selling concepts.

These concepts give you the foundation to understand why customers act the way they do and provide a

guide as to how to use your selling skills to overcome obstacles and increase sales. 

Successful Selling Steps 

If we consider the steps most successful sales representatives go through to increase their effectiveness

on sales calls, we will see there are three general areas for consideration:

1.       Business Planning

2.       The Sales Call (pre-call, sales call, post-call)

3.       Follow-Up 

Business planning is a critical step in ensuring your selling skills are most effective. Sales representatives

in the healthcare industry manage their territories as if they were running their own business. To be

successful in your sales territory you need to fully understand it before you attempt to call on customers.

This includes knowing which customers drive your business, what their “buying” style is so you can

match your selling style to it, managing an investment budget, managing your daily and weekly schedule,

and working with your team to implement the territory business plans. You can view the business

planning process as creating a blueprint for success. Most healthcare companies will give you a territory,

a list of target customers, the sales tools needed to influence your target customers and a budget. It is up

to you and your territory team to come up with a plan that will most effectively make use of these

resources to increase sales. 

6

Following the business planning process, there are three main steps to consider to improve your sales call

effectiveness:

1.       Pre-call planning (before you meet the customer)

2.       The sales call (face to face with the customer)

3.       Post-call analysis and follow-up (after your sales call)

Pre-call planning done prior to meeting your customer involves several steps such as reviewing past

customer call notes, setting call objectives and preparing sales tools to be most effective in the short time

with your customer. This will be covered in more detail shortly. 

During the actual sales call itself, there are several steps to be aware of: opening, presenting features and

benefits, probing, objection handling, etc. Making an effective sales call involves excellent skills within

each of these areas and we will cover them more in-depth in the coming chapters. 

After leaving each and every sales call, post-call analysis needs to be completed, and any follow-up

required accurately recorded and completed. These notes which you make post-call are what you will be

reviewing prior to your next appointment with your customers. Without having these notes, your

7

effectiveness on the next call will not be as high. 

One major goal of a healthcare sales representative is to be seen as a valued consultant by customers.

Once you are viewed by your target customers as an excellent and credible resource (and not just another

sales representative) you will have increased access and time with them – and increased face-to-face

selling time is a key ingredient for success in healthcare sales. Ensuring timely follow-up to customer

requests in a professional manner will go a long way in ensuring you become that value added consultant

in their practices. 

The Sales Cycle 

A sales cycle is the stages that a typical customer goes through before agreeing to purchase or use your

product. Although the ultimate goal is a sale, there are several stages which you must take the customer

through before you can ask for the business.  

In the first stage, called Introduction and Awareness, the customer is not yet aware that you or your

products exist. They may not even know about any problems they are currently facing because they have

not taken the time to consider them. Your goal with a customer at this stage is to introduce your products

and services and try to identify any problem areas which your product can solve for them, their patients

or the healthcare system. Moving a customer through this stage is sometimes not easy and requires

certain sales techniques. Techniques used to move a customer from this stage to the next one are rapport

building, probing, objection handling, and gaining feedback. Throughout this book you will learn how to

8

improve each of these skills to be successful in a healthcare sales role.  

The second stage is Identification. At this stage you need to convince the customer that a problem does

indeed exist. This is sometimes the hardest stage to get through as many customers will tell you that they

are happy with their current product. To move the customer through this stage, sales skills such as

presenting features and benefits, probing, gaining feedback, and the ability to handle objections will be

needed.  

In the third stage, the Knowledge stage, you must educate the customer on what your company and

products offer using the features and benefits of your products and or services. Without the proper

knowledge of what you and your company can offer (to the customer, the patient or the healthcare

system), the customer will not be able to evaluate his options properly. Excellent use of features and

benefits, probing, and objection handling will help you to move the customer through this stage to the

evaluation stage. 

The Evaluation stage is where the customer takes the time to compare your product to that which he is

currently using. It is sometimes extremely difficult to change the habits of a customer, so persuasion and

persistence is needed. Realizing where the customer is at within this sales cycle will help you to maintain

perspective and use the appropriate sales skills to move him along the sales cycle. This is where your

needs analysis is critical, as you want to ensure you are reinforcing, on a frequent basis, the benefits your

product or service offers versus your competition in addressing THAT particular customer’s needs. To

move the customer through this stage you need to present strong features and benefits, use excellent

9

competitive selling techniques in addition to probing and strong skills. 

In the final stage, the customer makes a Decision to use your product or service or your competitors. If

he has chosen your product, you can feel good about taking your customer through the sales cycle and

convincing him of the benefits of your product versus the competition. If the customer does not choose

your product or service, then your job will be to take him back to the evaluation stage so he can re-

evaluate the options and reconsider your product. Sometimes this is very difficult to do, as they may be

very happy with what they are currently using. You may have to take them all the way back to the

identification stage to find new opportunities or problems which your product can address and your

competitor cannot. This is a very dynamic model, and each customer you deal with will be at a different

stage in this cycle. It is your job to identify where that customer is and try to get him to the next stage

using effective selling techniques.

Think of the sales cycle as a series of steps that you are climbing. Before you reach the top step (the

sale), you have to walk the customer up each of the lower steps first. It is very rare that you will meet a

customer for the first time and walk away with a sale. You need to complete the steps in the cycle and

earn the right to ask for the business.

Another concept to keep in mind is that the time needed to move a customer through the sales cycle

varies based on several factors:

1.       Type of product – Healthcare sales products which are more expensive (such as capital equipment

10

for use in hospitals) often requires consensus from a committee before the contract is signed. As a result,

to get all members of the committee to agree takes quite a bit longer than a sale where only one customer

needs to say “yes”.

2.       Frequency of sales calls – The more frequently you are able to get face to face selling time with a

customer, the quicker you will be able to move them through the sales cycle…IF you have developed

excellent selling skills.

3.       Representative selling skills – Without effective selling skills, you will not be able to move

customers through the sales cycle. To move them more quickly through the sales cycle, you must

continually develop and improve on all of the sales skills listed in this book. 

Of the three listed here, representative selling skills is by far the most important one which affects the

time needed to move a customer through the sales cycle.

The Customer Environment 

Before we discuss each stage and the selling skills needed, we will consider the customer environment.

The healthcare customer environment and selling into it requires a significant amount of planning,

preparation, persistence and versatility to be effective. As you will learn, time is a very valuable

commodity in the healthcare office or clinic, and making effective use of your time is critical to move

that customer along the sales cycle to a decision which is favorable for your product or service. The key

11

to success in this environment is ensuring you are calling on the right customer, the right number of

times using the right message! 

Why is it getting more difficult to get time with our customers? 

Over the past several years, it has been getting more and more difficult to access customers in the

healthcare industry, and those that can be accessed are giving less and less time to sales representatives.

We will now have a look at some of the main reasons this is occurring:

1.       Time Pressures – Today’s professionals try to squeeze more work into a day. Some physicians see

between 30 and 60 patients per day. In addition to seeing patients, physicians need to finish patient

charts, fill out insurance and lawyer’s reports, return phone calls and attend meetings. This is in addition

to trying to have a life outside the office and spending quality time with their families. Five minutes with

a representative is five minutes they could have spent completing other tasks.

2.       Lack of Monetary Gain – Physicians do not get paid to see representatives but they do get paid to

see patients. If they could see a patient in the time it takes to talk to a representative then they are losing

money every time they talk to a representative. This reiterates the fact that you must provide value to

your target customers on each and every call if you want to continue to get face time with them.

3.       Number of Representatives – In many offices that see representatives, it is not uncommon for six

or more representatives to visit on any given day. The sheer number representatives can be

12

overwhelming, not only to the physician, but to the medical office assistants who have to deal with the

patients in the waiting room.

4.       Lack of Value Seen – This is the most important factor to keep in mind as you work on your

territory. If a physician truly believes that seeing a particular sales representative will add value to his

practice, he will take the time away from his patients to hear what that representative has to say.

However, if he feels that a representative will bring no value, he will likely not spend any time with him

or her. There can be various reasons for this, but the number one reason is that only the best

representatives take the time to identify “true” needs of each customer and sell to that particular need.

There are a lot of representatives who do not take the time to identify needs, involve the customer in the

sales call, or prepare for each call to ensure value is seen every time. Without providing value to your

key customers you will not be able to get adequate selling time to be effective.

Key Terms

To be most successful as a healthcare sales representative, you must understand two key terms: targeting

and frequency.

Targeting: The Right Customer 

When considering who your target customers are, there are two key questions to ask: how important is

this customer to your business and how accessible is the customer to you?

How important is this customer to your business?  

13

When considering this factor you need to look at not only how busy their practice is, but also what their

patient demographics are. Yes, you must call on customers who see many patients per day, but if they are

not the right types of patients for your products, then you are wasting your time. For example, if you are

selling a medication for high blood pressure and you are calling on a busy physician who sees mainly

younger women and children, this is not likely a good use of your time. It is crucial that you look at both

how busy your customer is and what types of patients they most commonly treat. Generally speaking,

the more patients a customer sees the better, as long as these are the types of patients your product will

help.

How does a representative find out what types of patients a customer may see?  

There are many ways including viewing the waiting room to profile the patients waiting to see the

physician, looking to see what types of product samples are on the shelves, and asking the medical office

assistant or local pharmacist what types of patients the area services. If all else fails, ask your physician!

They will usually give you a straight up answer as to the types of patients they look after. Just remember,

it’s not just the busy physicians who are important to you – they may be busy, but may not be seeing your

targeted patient population. If this is the case, they may not be a true target physician for you. 

How accessible is your customer?  

If you have a customer who is extremely busy and services the types of patients that would be a great fit

for your product, it makes sense that they should be a target for you. However, what if this physician is

not willing to see you as a sales representative even though you have tried many ways to see him or her?

14

In this situation, it may be wiser to take them off your target list and replace them with another customer

that you have access to. However, it is important to remember that just because you have tried a couple

of times to see this customer and have not had success, it does not mean they are not accessible. You

need to try every means possible (using all of the activities you read about in the Introduction to the

Pharmaceutical Sales Industry from PharmaCareer) to ensure that there is not some way that you can

access this customer. There are many times a customer seems inaccessible but somehow, someway, you

manage to make contact with them. These can end up being your best supporters as much of your

competition may have given up calling on them, giving you the opportunity to sell to them in a less

competitive environment. It is important to remember that on average you will need to make contact

with your targeted customers six to twelve times a year to make an impact. Seeing a customer once every

two years is not going to make much of an impact on your sales! 

15

Relationship between Sales and Marketing

 

Most people confuse between sales and marketing. It’s actually pretty straightforward: Marketers create

demand, and the sales team execute accordingly to fulfill that demand. Similar to design and marketing,

both teams share a symbiotic relationship – one cannot benefit without the other, yet they don’t speak the

same language. Each have their own jargons and lingoes they throw around one other, and it’s not

helping your company to grow. How can you put an end to the ceaseless sales and marketing dispute?

Let’s take a closer look at their dynamics.

We all know that poor communication discourages any form of relationship. A disconnect between your

teammates discourages your business efforts to maximize value for both your company and your

customers. Common conflicts include:

 Losing focus

You may think that joint metrics in sales and marketing saves time, money, and energy. On the contrary,

this culture is exactly what’s causing that blurry distinction between sales and marketing – when they’ve

led a successful campaign, everyone shares the reward. When all else fails, team members blame one

another.

Separatistic culture

Each team is too focused on individual tasks. Marketers work out the grand plan, sales wants to close the

deal ASAP. Marketers work behind the desk, sales are out in the field. Marketers are strategic thinkers

who are highly analytical and data-oriented, and they’re motivated by providing creative solutions for the

16

long haul. Sales wants to generate maximum revenue as they’re usually compensated by commissions,

quotas, bonuses, and so on.

 What about the customers?

We’re living in the digital era, and as a business leader it’s your responsibility for everyone in your team

to understand that consumers’ buying behaviors are changing.

For your product or service to successfully penetrate the new demand, you need to redesign your strategy

through a coherent series of campaigns, promotions, advertising, and other efforts.

This is where your marketing and salesforce must learn to cooperate, because no matter how brilliant the

plan is, your company will never profit when people simply don’t buy.

There are 4 essential steps a customer goes through before they decide to buy from you:

 

1. Awareness They know your existence. They look forward to seeing you again.

2. Consideration They go home and think about you – a sign that you’ve addressed their needs and

you promise to deliver.

3. Preference They like you more than your competitors, thanks to your excellent presentations and

proposals.

4. Conversion They’re ready to negotiate contracts and proceed to sales.

 

17

Converting leads to sales is tricky, and identifying qualified leads takes time. To foster strong customer

relationships, it takes a collaborative effort from every department of your company.

 

Teamwork: Two heads are better than one

True, your marketing plan should be solid, but it must also be flexible enough to integrate its

functions with the sales team. Similarly, salesforce must have a clear understanding of what is expected

out of each campaign.

When both teams start speaking the same language, they’re more engaged in executing every step of the

process from start to finish.

Align your sales and marketing operations to build on the following equities:

Loyalty This is the foundation for word-of-the-mouth marketing. At this point, your focus is to

educate and nurture first-time and regular customers. You’ve earned their trust, and you’ve got to

maintain that by giving quality service and continuous support.

Advocacy When customers are loyal to your brand, they help you build referrals for future

prospects. Consider it a success when your users, fans, and customers supports your brand more

than anything else.

In a nutshell, it’s your job as a leader to encourage effective communication among your teammates.

Instead of blaming one another, shift their focus on customers instead: What are their wants and needs?

Once demands are clearly outlined, it gets easier to guide your teams and define exactly you expect out of

each team.

18

Ultimately, your goal as a leader is to manage a stable brand and reputation. Everyone in your company

must commit and connect to remain consistent with your vision and mission.

Omeprazole

Drug Omeprazole

Omeprazole is a proton pump inhibitor used in the treatment of dyspepsia, peptic ulcer disease

(PUD), gastroesophageal reflux disease (GORD/GERD), laryngopharyngeal reflux (LPR), and

Zollinger-Ellison syndrome. It was first marketed in the US in 1989 by AstraZeneca under the brand

names Losec and Prilosec, and is now also available from generic manufacturers under various brand

names. AstraZeneca markets omeprazole as Losec, Antra, Gastroloc, Mopral, Omepral, and Prilosec.

Omeprazole is marketed as Zegerid by Santarus, Prilosec OTC by Procter & Gamble and Zegerid OTC

20

by Schering-Plough. In India it is available as OMEZ (FGP). Omeprazole is one of the most widely

prescribed drugs internationally and is available over the counter in some countries.

Pharmacology

Omeprazole is a racemate. It contains a tricoordinated sulfur atom in a pyramidal structure and

therefore can exist in equal amounts of both the S and R enantiomers. In the acidic conditions of the

stomach, both are converted to achiral products, which react with a cysteine group in H + /K

+ ATPase ,

thereby inhibiting the ability of the parietal cells to produce gastric acid.

Name change

In 1990, at the request of the U.S. Food and Drug Administration (FDA), the brand name Losec

was changed to Prilosec to avoid confusion with the diuretic Lasix (furosemide). Unfortunately, the new

name has led to confusion between omeprazole (Prilosec) and fluoxetine (Prozac), an antidepressant.

are greater than those for adults.

Alternative administrative options can be used for pediatric patients unable to swallow an intact

capsule.

Dosage forms:

Omeprazole is available as tablets and capsules (containing omeprazole or omeprazole magnesium) in

strengths of 10 mg, 20 mg, 40 mg, and in some markets 80 mg; and as a powder (omeprazole sodium) for

intravenous injection. Most oral omeprazole preparations are enteric-coated, due to the rapid degradation

of the drug in the acidic conditions of the stomach. This is most commonly achieved by formulating

enteric-coated granules within capsules, enteric-coated tablets, and the multiple-unit pellet system

(MUPS).

It is also available for use in injectable form (I.V.) in Europe, but not in the U.S. The injection pack is a

combination pack consisting of a vial and a separate ampule of reconstituting solution. Each 10 ml clear

glass vial contains a white to off-white lyophilised powder consisting of omeprazole sodium 42.6 mg

equivalent to 40 mg of omeprazole.

History

Omeprazole was first marketed in the U.S. in 1989 by Astra AB, now AstraZeneca under the brand

names Losec and Prilosec. An over the counter brand, Prilosec OTC, is available without prescription in

the US for treatment of heartburn. It is now also available from generic manufacturers under various

brand names.

In 1990, at the request of the U.S. Food and Drug Administration (FDA), the brand name Losec was

changed to Prilosec to avoid confusion with the diuretic Lasix (furosemide).[29] The new name has led to

confusion between omeprazole (Prilosec) and fluoxetine (Prozac), an antidepressant.[29]

AstraZeneca markets omeprazole as Losec, Antra, Gastroloc, Mopral, Omepral, and Prilosec.

Omeprazole is marketed as Zegerid by Santarus, Prilosec OTC by Procter & Gamble and Zegerid OTC

by Schering-Plough and as Segazole by Star Laboratories in Pakistan.[30][31] In the Philippines, Ajanta

Pharma markets omeprazole under the brand name Zegacid. Dr. Reddy's Laboratories markets it as Omez

in India, Russia, Romania, and South Africa. In Bangladesh Healthcare Pharmaceuticals Ltd. marketed

omeprazole under the brand name Opal. In Bangladesh Apex Pharma also markets omeprazole under the

brand name Aspra. It is also available under the brand name Rome 20 marketed by Rephco

Pharmaceuticals Ltd. In Bangladesh the brand leader in this market is Seclo. In Argentina it is made by

Bago Laboratories S.A. and available there and in Ecuador as Ulcozol. In Indonesia Darya-Varia

Laboratories marketed omeprazole as Ozid. In Brazil, omeprazole is produced by Multilab under the

name Lozeprel. In Spain it is produced by Cantabria Pharma S.L. under the name emeprotón. In

Bangladesh, Eskayef Bangladesh Limited also marketed omeprazole under the brand name Losectil. The

Acme Laboratories Limited marketed it under the brand name PPI.

25

In 1999, antiulcerants were the leading class of therapeutic drugs, with $15.6 billion in global sales. Of

that, Prilosec accounted for $5.91 billion, making it the best-selling drug on the market.[32]

Although Prilosec's U.S. patent expired in April 2001, AstraZeneca was able to delay the introduction of

generic versions through lawsuits and peripheral patent claims. It introduced Nexium as a patented

replacement drug.[33]

26

Omeprazole 10 mg, From U.K.

Omeprazole is available as tablets and capsules (containing omeprazole or omeprazole magnesium) in

strengths of 10 mg, 20 mg, 40 mg, and in some markets 80 mg; and as a powder (omeprazole sodium) for

intravenous injection. Most oral omeprazole preparations are enteric-coated, due to the rapid degradation

of the drug in the acidic conditions of the stomach. This is most commonly achieved by formulating

enteric-coated granules within capsules, enteric-coated tablets, and the multiple-unit pellet system

(MUPS).

It is also available for use in injectable form (I.V.) in Europe, but not in the U.S. The injection pack is a

combination pack consisting of a vial and a separate ampule of reconstituting solution. Each 10 ml clear

glass vial contains a white to off-white lyophilised powder consisting of omeprazole sodium 42.6 mg

equivalent to 40 mg of omeprazole.

Multiple unit pellet system

Omeprazole tablets manufactured by AstraZeneca (notably Losec/Prilosec) are formulated as a "multiple

unit pellet system" (MUPS). Essentially, the tablet consists of extremely small enteric-coated granules

(pellets) of the omeprazole formulation inside an outer shell. When the tablet is immersed in an aqueous

solution, as happens when the tablet reaches the stomach, water enters the tablet by osmosis. The

contents swell from water absorption causing the shell to burst, releasing the enteric-coated granules. For

most patients, the multiple-unit pellet system is of no advantage over conventional enteric-coated

preparations. Patients for which the formulation is of benefit include those requiring nasogastric tube

feeding and those with difficulty swallowing (dysphagia) because the tablets can be mixed with water

ahead of time, releasing the granules into a slurry form, which is easier to pass down the feeding tube or

to swallow than the pill.[citation needed] The granules are manufactured in a fluid air bed system. Sugar spheres

27

in suspension are sequentially sprayed with aqueous suspensions of omeprazole, a protective layer, an

enteric coating and an outer layer to reduce granule aggregation. The granules are mixed with other

excipients and compressed into tablets. Finally, the tablets are film-coated to improve the stability and

appearance of the preparation. Also available in a liquid suspension form, from a compounding

pharmacy. Ideal for infants.

Immediate release formulation

In June 2004 the FDA approved an immediate release preparation of omeprazole and sodium bicarbonate

that does not require an enteric coating. This preparation employs sodium bicarbonate as a buffer to

protect omeprazole from gastric acid degradation. This allows for the production of chewable tablets.

This combination preparation is marketed in the United States by Santarus under the brand name Zegerid.

Zegerid is marketed as capsules, chewable tablets, and powder for oral suspension. Zegerid is most useful

for those patients who suffer from nocturnal acid breakthrough (NAB) or those patients who desire

immediate relief. In India it is marketed by Dr. Reddy's Laboratories as powder formulation with the

brand name OMEZ-INSTA. It is reported to have additional benefits with patients suffering from

alcoholic gastritis and life-style associated gastritis.

28

Mechanism of Action:

Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress

gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface

of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the

gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the

final step of acid production. This effect is dose-related and leads to inhibition of both basal and

stimulated acid secretion irrespective of the stimulus. Animal studies indicate that after rapid

disappearance from plasma, omeprazole can be found within the gastric mucosa for a day or more.

Animal Pharmacology

Pharmacodynamics:

Antisecretory Activity:

After oral administration, the onset of the antisecretory effect of omeprazole occurs within one hour, with

the maximum effect occurring within two hours. Inhibition of secretion is about 50% of maximum at 24

hours and the duration of inhibition lasts up to 72 hours. The antisecretory effect thus lasts far longer than

would be expected from the very short (less than one hour) plasma half-life, apparently due to prolonged

binding to the parietal H+/K+ ATPase enzyme. When the drug is discontinued, secretory activity returns

gradually, over 3 to 5 days. The inhibitory effect of omeprazole on acid secretion increases with repeated

once-daily dosing, reaching a plateau after four days.

29

Results from numerous studies of the antisecretory effect of multiple doses of 20 mg and 40 mg of

omeprazole in normal volunteers and patients are shown below. The “max” value represents

determinations at a time of maximum effect (2-6 hours after dosing), while “min” values are those 24

hours after the last dose of omeprazole.

Serum Gastric Effects

In studies involving more than 200 patients, serum gastrin levels increased during the first 1 to 2 weeks

of once-daily administration of therapeutic doses of omeprazole in parallel with inhibition of acid

secretion. No further increase in serum gastrin occurred with continued treatment. In comparison with

histamine H2-receptor antagonists, the median increases produced by 20 mg doses of omeprazole were

higher (1.3 to 3.6 fold vs. 1.1 to 1.8 fold increase). Gastrin values returned to pretreatment levels, usually

within 1 to 2 weeks after discontinuation of therapy.

Enterochromaffin-like (ECL) Cell Effects

Human gastric biopsy specimens have been obtained from more than 3000 patients treated with

omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased

with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these

patients. However, these studies are of insufficient duration and size to rule out the possible influence of

long-term administration of omeprazole on the development of any premalignant or malignant

conditions.

Other Effects

30

Systemic effects of omeprazole in the CNS, cardiovascular and respiratory systems have not been found

to date. Omeprazole, given in oral doses of 30 or 40 mg for 2 to 4 weeks, had no effect on thyroid

function, carbohydrate metabolism, or circulating levels of parathyroid hormone, cortisol, estradiol,

testosterone, prolactin, cholecystokinin or secretin.

No effect on gastric emptying of the solid and liquid components of a test meal was demonstrated after a

single dose of omeprazole 90 mg. In healthy subjects, a single I.V. dose of omeprazole (0.35 mg/kg) had

no effect on intrinsic factor secretion. No systematic dose-dependent effect has been observed on basal or

stimulated pepsin output in humans.

However, when intragastric pH is maintained at 4.0 or above, basal pepsin output is low, and pepsin

activity is decreased.

As do other agents that elevate intragastric pH, omeprazole administered for 14 days in healthy subjects

produced a significant increase in the intragastric concentrations of viable bacteria. The pattern of the

bacterial species was unchanged from that commonly found in saliva. All changes resolved within three

days of stopping treatment.

Pharmacokinetics

Absorption and Distribution:

OMEPRAZOLE Delayed-Release Capsules contain an enteric-coated granule formulation of omeprazole

(because omeprazole is acid-labile), so that absorption of omeprazole begins only after the granules leave

the stomach. Absorption is rapid, with peak plasma levels of omeprazole occurring within 0.5 to 3.5

hours. Peak plasma concentrations of omeprazole and AUC are approximately proportional to doses up to

31

40 mg, but because of a saturable first-pass effect, a greater than linear response in peak plasma

concentration and AUC occurs with doses greater than 40 mg. Absolute bioavailability (compared with

intravenous administration) is about 30-40% at doses of 20-40 mg, due in large part to presystemic

metabolism. In healthy subjects the plasma half-life is 0.5 to 1 hour, and the total body clearance is 500-

600 mL/min.

Based on a relative bioavailability study, the AUC and Cmax of OMEPRAZOLE (omeprazole

magnesium) for Delayed-Release Oral Suspension were 87% and 88% of those for OMEPRAZOLE

Delayed-Release Capsules, respectively.

The bioavailability of omeprazole increases slightly upon repeated administration of OMEPRAZOLE

Delayed-Release Capsules.

OMEPRAZOLE Delayed-Release Capsule 40 mg was bioequivalent when administered with and without

applesauce. However, OMEPRAZOLE Delayed-Release Capsule 20 mg was not bioequivalent when

administered with and without applesauce. When administered with applesauce, a mean 25% reduction in

Cmax was observed without a significant change in AUC for OMEPRAZOLE Delayed-Release Capsule

20 mg. The clinical relevance of this finding is unknown.

Distribution

Protein binding is approximately 95%.

Metabolism:

Omeprazole is extensively metabolized by the cytochrome P450 (CYP) enzyme system.

32

Excretion:

Following single dose oral administration of a buffered solution of omeprazole, little if any unchanged

drug was excreted in urine. The majority of the dose (about 77%) was eliminated in urine as at least six

metabolites. Two were identified as hydroxyomeprazole and the corresponding carboxylic acid. The

remainder of the dose was recoverable in feces. This implies a significant biliary excretion of the

metabolites of omeprazole. Three metabolites have been identified in plasma — the sulfide and sulfone

derivatives of omeprazole, and hydroxyomeprazole. These metabolites have very little or no antisecretory

activity.

Side Effects:

The safety data described below reflects exposure to OMEPRAZOLE Delayed-Release Capsules in 3096

patients from worldwide clinical trials (465 patients from US studies and 2,631 patients from

international studies). Indications clinically studied in US trials included duodenal ulcer, resistant ulcer,

and Zollinger-Ellison syndrome. The international clinical trials were double blind and open-label in

design. The most common adverse reactions reported (i.e., with an incidence rate ≥ 2%) from

OMEPRAZOLE-treated patients enrolled in these studies included headache (6.9%), abdominal pain

(5.2%), nausea (4.0%), diarrhea (3.7%), vomiting (3.2%), and flatulence (2.7%).

Additional adverse reactions that were reported with an incidence ≥ 1% included acid regurgitation

(1.9%), upper respiratory infection (1.9%), constipation (1.5%), dizziness (1.5%), rash (1.5%), asthenia

(1.3%), back pain (1.1%), and cough (1.1%).

33

The clinical trial safety profile in patients greater than 65 years of age was similar to that in patients 65

years of age or less.

The clinical trial safety profile in pediatric patients who received OMEPRAZOLE Delayed-Release

Capsules was similar to that in adult patients. Unique to the pediatric population, however, adverse

reactions of the respiratory system were most frequently reported in both the 1 to < 2 and 2 to 16 year age

groups (75.0% and 18.5%, respectively). Similarly, fever was frequently reported in the 1 to 2 year age

group (33.0%), and accidental injuries were reported frequently in the 2 to 16 year age group (3.8%).[See

Use in Specific Populations]

Clinical Trials Experience with OMEPRAZOLE in Combination Therapy for H. pylori Eradication

In clinical trials using either dual therapy with OMEPRAZOLE and clarithromycin, or triple therapy with

OMEPRAZOLE, clarithromycin, and amoxicillin, no adverse reactions unique to these drug

combinations were observed. Adverse reactions observed were limited to those previously reported with

omeprazole, clarithromycin, or amoxicillin alone.

Dual Therapy (OMEPRAZOLE/clarithromycin)

Adverse reactions observed in controlled clinical trials using combination therapy with OMEPRAZOLE

and clarithromycin (n = 346) that differed from those previously described for OMEPRAZOLE alone

were taste perversion (15%), tongue discoloration (2%), rhinitis (2%), pharyngitis (1%) and flu-syndrome

(1%). (For more information on clarithromycin, refer to the clarithromycin prescribing information,

Adverse Reactions section).

Triple Therapy (OMEPRAZOLE/clarithromycin/amoxicillin)

34

The most frequent adverse reactions observed in clinical trials using combination therapy with

OMEPRAZOLE, clarithromycin, and amoxicillin (n = 274) were diarrhea (14%), taste perversion (10%),

and headache (7%). None of these occurred at a higher frequency than that reported by patients taking

antimicrobial agents alone. (For more information on clarithromycin or amoxicillin, refer to the

respective prescribing information, Adverse Reactions sections).

The following adverse reactions have been identified during post-approval use of OMEPRAZOLE

Delayed-Release Capsules. Because these reactions are voluntarily reported from a population of

uncertain size, it is not always possible to reliably estimate their actual frequency or establish a causal

relationship to drug exposure.

Body As a Whole: Hypersensitivity reactions including anaphylaxis, anaphylactic shock, angioedema,

bronchospasm, interstitial nephritis, urticaria, (see also Skin below); fever; pain; fatigue; malaise;

peripheral edema

Endocrine: Gynecomastia

Gastrointestinal: Pancreatitis (some fatal), anorexia, irritable colon, fecal discoloration, esophageal

candidiasis, mucosal atrophy of the tongue, stomatitis, abdominal swelling, dry mouth. During treatment

35

with omeprazole, gastric fundic gland polyps have been noted rarely. These polyps are benign and appear

to be reversible when treatment is discontinued.

Gastroduodenal carcinoids have been reported in patients with ZE syndrome on long-term treatment with

OMEPRAZOLE. This finding is believed to be a manifestation of the underlying condition, which is

known to be associated with such tumors.

Hepatic: Liver disease including hepatic failure (some fatal), liver necrosis (some fatal), hepatic

encephalopathy hepatocellular disease, cholestatic disease, mixed hepatitis, jaundice, and elevations of

liver function tests [ALT, AST, GGT, alkaline phosphatase, and bilirubin]

Nervous System/Psychiatric: Psychiatric and sleep disturbances including depression, agitation,

aggression, hallucinations, confusion, insomnia, nervousness, apathy, somnolence, anxiety, and dream

abnormalities; tremors, paresthesia; vertigo

Respiratory: Epistaxis, pharyngeal pain

36

Skin: Severe generalized skin reactions including toxic epidermal necrolysis (some fatal), Stevens-

Johnson syndrome, and erythema multiforme; photosensitivity; urticaria; rash; skin inflammation;

pruritus; petechiae; purpura; alopecia; dry skin; hyperhidrosis

thrombocytopenia, leukopenia, leucocytosis

DRUG INTERACTIONS:

Interference with Antiretroviral Therapy:

Concomitant use of atazanavir and nelfinavir with proton pump inhibitors is not recommended. Co-

administration of atazanavir with proton pump inhibitors is expected to substantially decrease atazanavir

plasma concentrations and may result in a loss of therapeutic effect and the development of drug

37

resistance. Co-administration of saquinavir with proton pump inhibitors is expected to increase

saquinavir concentrations, which may increase toxicity and require dose reduction.

Omeprazole has been reported to interact with some antiretroviral drugs. The clinical importance and the

mechanisms behind these interactions are not always known. Increased gastric pH during omeprazole

treatment may change the absorption of the antiretroviral drug. Other possible interaction mechanisms are

via CYP 2C19.

Reduced concentrations of atazanavir and nelfinavir

For some antiretroviral drugs, such as atazanavir and nelfinavir, decreased serum levels have been

reported when given together with omeprazole. Following multiple doses of nelfinavir (1250 mg, twice

daily) and omeprazole (40 mg daily), AUC was decreased by 36% and 92%, Cmax by 37% and 89% and

Cmin by 39% and 75% respectively for nelfinavir and M8. Following multiple doses of atazanavir (400

mg, daily) and omeprazole (40 mg, daily, 2 hr before atazanavir), AUC was decreased by 94%, Cmax by

96%, and Cmin by 95%. Concomitant administration with omeprazole and drugs such as atazanavir and

nelfinavir is therefore not recommended.

Increased concentrations of saquinavir

For other antiretroviral drugs, such as saquinavir, elevated serum levels have been reported, with an

increase in AUC by 82%, in Cmax by 75%, and in Cmin by 106%, following multiple dosing of

saquinavir/ritonavir (1000/100 mg) twice daily for 15 days with omeprazole 40 mg daily co-administered

days 11 to 15. Therefore, clinical and laboratory monitoring for saquinavir toxicity is recommended

38

during concurrent use with PRILOSEC. Dose reduction of saquinavir should be considered from the

safety perspective for individual patients.

There are also some antiretroviral drugs of which unchanged serum levels have been reported when given

with omeprazole.

Drugs for Which Gastric pH Can Affect Bioavailability

Because of its profound and long lasting inhibition of gastric acid secretion, it is theoretically possible

that omeprazole may interfere with absorption of drugs where gastric pH is an important determinant of

their bioavailability (e.g., ketoconazole, ampicillin esters, and iron salts). In the clinical trials, antacids

were used concomitantly with the administration of PRILOSEC.

Effects on Hepatic Metabolism/Cytochrome P-450 Pathways

Omeprazole can prolong the elimination of diazepam, warfarin and phenytoin, drugs that are metabolized

by ^oxidation in the liver. There have been reports of increased INR and prothrombin time in patients

receiving proton pump inhibitors, including omeprazole, and warfarin concomitantly. Increases in INR

and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump

inhibitors and warfarin may need to be monitored for increases in INR and prothrombin time.

Although in normal subjects no interaction with theophylline or propranolol was found, there have been

clinical reports of interaction with other drugs metabolized via the cytochrome P450 system (e.g.,

cyclosporine, disulfiram, benzodiazepines). Patients should be monitored to determine if it is necessary to

adjust the dosage of these drugs when taken concomitantly with PRILOSEC.

39

Concomitant administration of omeprazole and voriconazole (a combined inhibitor of CYP2C19 and

CYP3A4) resulted in more than doubling of the omeprazole exposure. Dose adjustment of omeprazole is

not normally required. However, in patients with Zollinger-Ellison syndrome, who may require higher

doses up to 240 mg/day, dose adjustment may be considered. When voriconazole (400 mg Q12h x 1 day,

then 200 mg x 6 days) was given with omeprazole (40 mg once daily x 7 days) to healthy subjects, it

significantly increased the steady-state Cmax and AUC0-24 of omeprazole, an average of 2 times (90%

CI: 1.8, 2.6) and 4 times (90% CI: 3.3, 4.4) respectively as compared to when omeprazole was given

without voriconazole.

Omeprazole acts as an inhibitor of CYP 2C19. Omeprazole, given in doses of 40 mg daily for one week

to 20 healthy subjects in cross over study, increased Cmax and AUC of cilostazol by 18% and 26%

respectively. Cmax and AUC of one of its active metabolites, 3,4-dihydro-cilostazol, which has 4-7 times

the activity of cilostazol, were increased by 29% and 69% respectively. Co-administration of cilostazol

with omeprazole is expected to increase concentrations of cilostazol and its above mentioned active

metabolite. Therefore a dose reduction of cilostazol from 100 mg b.i.d. to 50 mg b.i.d. should be

considered.

40

Before taking omeprazole, tell your doctor if you are taking any of the following drugs:

* a blood thinner such as warfarin (Coumadin);

* clopidogrel (Plavix);

* atazanavir (Reyataz);

* disulfiram (Antabuse);

* cyclosporine (Gengraf, Neoral, Sandimmune);

(Ativan), temazepam (Restoril), clorazepate (Tranxene), chlordiazepoxide (Librium), and others.

Nonclinical Toxicology:

Carcinogenesis, Mutagenesis, Impairment of Fertility:

In two 24-month carcinogenicity studies in rats, omeprazole at daily doses of 1.7, 3.4, 13.8, 44.0 and

140.8 mg/kg/day (about 0.7 to 57 times a human dose of 20 mg/day, as expressed on a body surface area

41

basis) produced gastric ECL cell carcinoids in a dose-related manner in both male and female rats; the

incidence of this effect was markedly higher in female rats, which had higher blood levels of omeprazole.

Gastric carcinoids seldom occur in the untreated rat. In addition, ECL cell hyperplasia was present in all

treated groups of both sexes. In one of these studies, female rats were treated with 13.8 mg

omeprazole/kg/day (about 6 times a human dose of 20 mg/day, based on body surface area) for one year,

and then followed for an additional year without the drug. No carcinoids were seen in these rats. An

increased incidence of treatment-related ECL cell hyperplasia was observed at the end of one year (94%

treated vs 10% controls). By the second year the difference between treated and control rats was much

smaller (46% vs 26%) but still showed more hyperplasia in the treated group. Gastric adenocarcinoma

was seen in one rat (2%). No similar tumor was seen in male or female rats treated for two years. For this

strain of rat no similar tumor has been noted historically, but a finding involving only one tumor is

difficult to interpret. In a 52-week toxicity study in Sprague-Dawley rats, brain astrocytomas were found

in a small number of males that received omeprazole at dose levels of 0.4, 2, and 16 mg/kg/day (about

0.2 to 6.5 times the human dose on a body surface area basis). No astrocytomas were observed in female

rats in this study. In a 2-year carcinogenicity study in Sprague-Dawley rats, no astrocytomas were found

in males or females at the high dose of 140.8 mg/kg/day (about 57 times the human dose on a body

surface area basis). A 78-week mouse carcinogenicity study of omeprazole did not show increased tumor

occurrence, but the study was not conclusive. A 26-week p53 (+/-) transgenic mouse carcinogenicity

study was not positive.

Omeprazole was positive for clastogenic effects in an in vitro human lymphocyte chromosomal

aberration assay, in one of two in vivo mouse micronucleus tests, and in an in vivo bone marrow cell

42

chromosomal aberration assay. Omeprazole was negative in the in vitro Ames test, an in vitro mouse

lymphoma cell forward mutation assay, and an in vivo rat liver DNA damage assay.

Omeprazole at oral doses up to 138 mg/kg/day in rats (about 56 times the human dose on a body surface

area basis) was found to have no effect on fertility and reproductive performance.

OVERDOSE:

Reports have been received of overdosage with omeprazole in humans. Doses ranged up to 2400 mg (120

times the usual recommended clinical dose). Manifestations were variable, but included confusion,

drowsiness, blurred vision, tachycardia, nausea, vomiting, diaphoresis, flushing, headache, dry mouth,

and other adverse reactions similar to those seen in normal clinical experience.

Symptoms were transient, and no serious clinical outcome has been reported when PRILOSEC was taken

alone. No specific antidote for omeprazole overdosage is known. Omeprazole is extensively protein

bound and is, therefore, not readily dialyzable. In the event of overdosage, treatment should be

symptomatic and supportive.

Single oral doses of omeprazole at 1350, 1339, and 1200 mg/kg were lethal to mice, rats, and dogs,

respectively. Animals given these doses showed sedation, ptosis, tremors, convulsions, and decreased

activity, body temperature, and respiratory rate and increased depth of respiration.

MISSED DOSE:

43

If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed

dose and resume your usual dosing schedule. Do not double the dose to catch up.

CONTRAINDICATIONS:

OMEPRAZOLE Delayed-Release Capsules are contraindicated in patients with known hypersensitivity

to substituted benzimidazoles or to any component of the formulation. Hypersensitivity reactions may

include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, and urticaria

STORAGE:
