At the Pharmacy Department
• Data entry operators electronically transcribes and translates the nurses electronic requisition for the medicine onto a printed medication order sheet.
Medication procedure of IPD
At the Pharmacy Department
• Dispensers physically procure medicine from the shelves to the dispensing table according to the printed medication order.• Then medicines are kept in a small medication carts along with the printed medication order sheet.
Medication procedure of IPD
At the Pharmacy Department
• Pharmacists cross-check the medication.• After confirming proper dispensing pharmacy aide bag all the medications into a bag (patient wise) and attaches the medication order along with it.• Labeling can also done if necessary.
Medication procedure of IPD
At the Pharmacy Department
• Pharmacy Aides carry the bags and carry it to individual floors.• Submits the medications patient wise to the nurses responsible in the floors and sub- floors.

Check Before making indent for patient in
IHISPatient ID Number.Patient BED Number.Patient Name.Dose and Dosage form written in prescription.Reserve medicine in patient cabinet.Last indent receive paper.
Should be very careful about….
Reading of prescription Receiving of medicine. Double indenting. Return medicine. Return of fridge items. DDA box handover. Route of administration Storage and expiry of medicine.
Should know about the medicine you are receiving for your patients…
What is the prescribed dosage?
How it should be taken?
Purpose of medicine.
what are common side effects of the medicine ?
DRUG STORAGE
Proper storage of medication is always an important consideration during periods of extreme heat or cold. Drugs can undergo physical, chemical & microbial changes on storage.
Recommended storage conditions:Store below -50C (freeze)Store between (2 to 8)0C (refrigerate, do not
freeze)Store below 250C (air conditioning)Store below 300C (room temperature)
DRUG STORAGE
Drug Storage Room Standards:
A lockable room Adequate lighting A temperature of below 250C, with air conditioning
units that operate 24 hrs per day & are connected to an emergency power supply.
A vaccine refrigerator for storage of vaccines & anti-venom.
A nominated refrigerator for cold storage of pharmaceutical products that requires refrigeration.
Adequate shelving for appropriate storage of the different categories of drugs.
DRUG CATEGORIES
All drugs are grouped in the following categories:
Refrigerated ( Heat sensitive products)Oral ( solid & liquid )Injectable (IV & IM)TopicalInfusionInhalationCosmeticLocal Purchase
Criteria of storage1. Always read the storage directions on each
medication label. 2. Keep medications in their original container. 3. Never combine different medications into one
bottle.4. Never store multiple medications in a plastic bag
Store medications in a cool, dry place 5. Avoid storing medications in areas of high
humidity.6. If a medication is required to be stored in the
refrigerator, be careful not to store it in the freezer.
DRUG STABILITY
Drug stability means the ability of the pharmaceutical dosage form to maintain the physical, chemical, therapeutic & microbial properties during the time of storage & usage by the patient.
Expiry Dates
Expiry date means that drug can not be used after this date due to the chance of chemical degradation, harmful to patient or low potency.
DRUG STABILITY
If the expiry date is expressed as month/year only (e.g., 3/2013), this shall be interpreted to mean that the drug may be safely used through the last day of that month, i.e., 3/31/2013.
If the expiration date is expressed as month/day/year (e.g., 15/3/2013), this shall be interpreted to mean that the drug may be safely used through that day only.
DRUG STABILITY
Chemical stability of the active ingredient
As the rate of decomposition usually doubles for every 100C rise in temperature, it is important to comply with the storage conditions specified on the container.
DRUG STABILITY
Once opened, the shelf-life of some products, e.g. eye drops, will be determined not by decomposition of the active drug but by the risk of microbial contamination.
Stability after opening drug container
The stability of products is variable. A product which is stable in its container may become unstable once the container is opened.
DRUG STABILITY
The expiry date will be shorter in case of-
Eye drops: can be used for one month after opening the droppers.
Antibiotic syrups & suspensions: generally can be used for one week by storage in room temperature & for two weeks by storage in refrigerator.
DRUG STABILITY
Ampoules: must be used immediately but the vials (multi-dose) are stable for 24 h in the presence of preservatives.
Nebulizer solution: can be used for one month after opening.
Insulin: once punctured, it must be used within 28 days.
Syrup/Suspension (except antibiotics): can be used for one month after opening.
Tablets & capsules: remain stable in the package but after removal expiry date will be changed.
DRUG STABILITY
Factors affecting drug stability:Temperature: high temperature accelerate
oxidation, reduction & hydrolysis reaction which leads to drug degradation.
PH: acidic & alkaline pH influence the rate of decomposition of most drugs. Many drugs are stable between pH 4 - 8.
Moisture: water catalyses chemical reactions as oxidation, hydrolysis & reduction reaction. Water promotes microbial growth.
Light: affects drug stability through its energy or thermal effect which leads to oxidation.
Medication error
Objectives of evaluation of dispensing errors
• To determine the dispensing errors.• To determine associated factors with them. • To suggest preventive actions.• To evaluate role of pharmacists.
Medication error
Causes of errors in Hospital• The most frequent cause of mistake was misreading the prescription due to poor handwriting.• The typing or computer error because of misreading.• Lack of knowledge about the brand name or generic name of the drugs/medicines during typing by nurses.• Disagree to consult with doctors if nurses do not understand the prescription.
Medication error
Causes of errors in Hospital• The errors to do with similar drug names or similar packaging (Frusin Inj., Zydol Inj.,Kolosal IV infusion, Koloride IV Infusion, Hydralazine, Hydroxyzine)• Interruptions are the biggest cause (telephone interruption, busy counter business, query from member of staff, etc).• Lack of concentration during dispensing, Gossip during dispensing due to presence of more personnel, Multi-task.
Medication error
Causes of errors in Hospital• New or unusual staffs are also significant.• Failure to check, Poor communication, Job dissatisfaction, No breaks, Failure to follow standard operating procedures, Lighting etc.• The final point is the time of day problem. This might be first thing in the morning for some people or last thing at night for others.
Medication error
Factors of errors in Hospital
• Inexperience employee• Lack of training• Poor Communication (Nurse, pharmacist & physicians)• Poor Handwriting• Lack of knowledge (Generic & Brand)• Lack of training on IHIS software• Gossip• Dissatisfaction
Medication error
Factors of errors in Hospital
• Too many customers • Lack of concentration • Staff shortage • Similar drug names • No time to counsel • Misinterpreted prescription • Haphazard arrangement of drugs
Medication Safety Tips to avoid serious medication errors in hospital
1. Create IHIS prescription by using patient ID not by name or bed.
2. After putting patient ID check the name and bed number.3. Write the medicine if you can read the prescription
easily.4. Don’t gage if you have any confusion in handwriting.5. Consult with your doctor if any confusion.6. Check the dose of drug as OD, TD, BD or stat.7. Check what the dosage form doctor advice like Injection
(IV/IM), tablet, capsule, cream, ointment, syrup, suspension, etc.

Timing of Drugs - Before or After Food
Taking Drugs Before FoodFor quick action/fast absorptionFor acid sensitive drugs
Some drugs need to be absorbed quickly to have an effect, such as nitrates in angina, drugs to help sleep (hypnotics), drugs to reduce agitation (sedatives) & drugs to reduce vomiting . As food can slow the absorption of these drugs, they need to be taken on an empty stomach.
Timing of Drugs - Before or After Food
The acid in the stomach breaks down some drugs, so delayed emptying will mean that more of the drug is broken down, and less of the drug is available, so it will be less effective.
Some Medications which should be taken on an EMPTY stomach:
Alendronate, Bisacodyl, Captopril, Sucralfate, Azithromycin, Co-trimoxazole, Omeprazole, Lansoprazole, Levothyroxine, loratadine, Rifampin, Methotrexate Mycophenolate, Tetracycline ……….etc.
Timing of Drugs - Before or After Food
Taking Drugs With or After FoodFor drugs causing stomach upsetFor less soluble drugs
The acid in the stomach changes some drugs, making them more soluble and so more easily absorbed. This means that the drug will be more effective.
Timing of Drugs - Before or After Food
NSAIDs can cause stomach upsets by increasing gastric secretion. Taking these drugs with food can reduce the irritation to the stomach lining.
Timing of Drugs - Before or After Food
Some drugs have to be taken during or after meals to be effective – for example,
Orlistat is designed to block the absorption of some of the fat in food as a treatment for obesity.
Over the Counter (OTC) medications
OTC medications are those medicines that do not require a prescription from a physician and are readily available to the public. This does not mean that they do not need to be taken carefully.
The most commonly used OTC medicines are : Pain Relievers Antihistamines Decongestants Cough medicines
Over the Counter (OTC) medications
Pain RelieversNSAIDS (non-steroidal anti-inflammatory
drugs) such as paracetamol, aspirin, ibuprofen,ketoprofen etc.
NSAIDS work by blocking the synthesis prostaglandins, which are involved in injury or infection and thus reduce pain, fever and inflammation.
Over the Counter (OTC) medications
NSAIDS can cause stomach upset and occasional gastrointestinal bleeding.
AntihistaminesHistamines are chemicals in our bodies that
produce itching and allergy responses. Antihistamines block these. Some common antihistamines are diphenhydramine HCl , chlorpheniramine etc.
Over the Counter (OTC) medications
Antihistamines can cause drowsiness. Be careful driving or doing any dangerous work. But, the Non-sedating antihistamines do not cause drowsiness and are now OTC. Some common antihistamines are loratadine, desloratadine, cetrizine & fexofenadine.
DecongestantsThese medicines work by shrinking/constricting
blood vessels in the nose and decrease congestion. The only over the counter decongestant is pseudoephedrine.
Over the Counter (OTC) medications
Cough Medicines
Cough medicines are two types: antitussives (anti cough) and expectorants (mucous reducer)
Dextromethorphan is the antitussive in most cough medicines.
Guaifensin is the expectorant that is mostly used. Cough Medicines can cause agitation and
confusion for some users.
Medication Safety Tips to avoid serious medication errors in house
Never take medication intended for someone elseNever keep medications that are expiredNever combine multiple medications in the same bottleNever take medication that is not clearly markedDon't expect immediate resultsDon't stop taking your medication just because you feel
better especially, antibiotics.Keep all medication away from childrenTo know clearly about existing drug-drug interactions.
Conclusion
Pharmacists should ensure that “right”patient is receiving the “right” drug in a “right”Dose at the right timePharmacists and other health careprofessionals involved in the medication useprocess must work together to develop a systemsapproach to medication.
