“FEMININE FOREVER” By Dr. Robert Wilson 1966
Menopause is a “ living decay in which women descended into a vapid cow-like state. Supplemental estrogen would almost magically transform the dull cow into a supple,younger-looking wife and mother. She would not only feel better but also make those around her feel better –especially her partner in bed”

MANAGEMENT OF MENOPAUSAL SYMPTOMS
Case Study # 1
• A 48-year-old airline attendant is suffering from severe and disruptive vasomotor symptoms.
• She had her last period 18 months ago. She has had significant problems with sleep disturbance, which are greatly impacting her ability to perform at work where she does many of the trans-Pacific routes.
• She often suffers vaginal dryness and chafing by the end of a long flight.
• She is worried about her ability to remember pills, or not get them mixed up as she regularly crosses the date line.

Why Consider Hormone Therapy?
HT is the most efficacious therapy for VMS
Cochrane database review showed1
– 75% reduction in frequency for any HT
– Significant reduction in hot flash severity
– Combination of E+P slightly more effective than E alone
• Progestin alone has also demonstrated some efficacy2

Adjusted mean number of vasomotor symptoms per day, by study group
Why bioidenticals?
• Response to 2002 WHI and suspicion of traditional medicine
• Perception of safer alternative – fear of cancer (especially breast cancer) and traditional HT
• Patients still having symptoms
• Wider advertising and broad availability (e.g., Internet)
• Patient comfort with alternative medicines
What is available for women?
Pharmaceutical standardized products • 17β-estradiol – oral and transdermal via patch or gel
• Micronized progesterone in peanut oil
Compounded with prescription by physician
for pharmacist • Customized estrogen mixtures of 80-90% estriol with 10-20%
estradiol (Bi-Est) – 1.25 and 2.5 mg
• Older Tri-Est contained 80% estriol, 10% estradiol and 10% estrone

Non-hormonal Medications for VMS
Gabapentin1 600 mg HS for night sweats
600-2400 mg/d in 3 divided doses
Effective for VMS, no impact on mood
Side effects in 25% of women (headache, dizziness, disorientation)
Clonidine2 Mildly effective at 0.05-0.075 mg bid
12% report reduction of >75%
Most common side effects: dry mouth, constipation, fatigue, restless sleep
SSRI/SNRI2-4 Dosage depends on SSRI/SNRI
Mostly studied in breast cancer survivors
Variable improvements (up to 79% reduction in VMS)
Reduction in severity and frequency

MANAGEMENT OF MENOPAUSAL SYMPTOMS:
FOCUS ON TRANSDERMAL ESTROGENS
Why Transdermal? Why Now?
• Needs assessment revealed gaps in practitioner knowledge
• Extensive information on oral hormone therapy; only delivery system looked at in WHI
• Since then – information has continued to evolve over past 10 years
• New science on transdermal delivery system
• There is a difference

Transdermal Estrogens: Impact on Cardiovascular Risk Factors
• Estrogen and Thromboembolism Risk (ESTHER) study1 – Lower risk of VTE compared with oral E2
• Markers of inflammation unaffected2
• Triglycerides decreased3
• Less effect on SHBG and TBG2
• Less favourable for HDL and LDL changes4 - CEE alone and CEE + MPA have a favourable effect on HDL-C
• Decreased CV risk in patients with metabolic syndrome5-7

Estrogen Therapy: Smoking Impacts Selection of Route of Administration
Smoking
– Free E2 levels may be lower in smokers ( liver metabolism; sex-hormone-binding globulin)1,2
– Increased dose of oral E may be required
– Transdermal E may be beneficial
ERT = estrogen replacement therapy; E2 = estradiol; E = estrogen
MANAGEMENT OF MENOPAUSAL SYMPTOMS:
FOCUS ON THE PROGESTOGENS
Available Progestogens
• Micronized progesterone (natural)
– Prometrium®
– Chemically identical to endogenous progesterone
– Only natural agent approved by Health Canada & U.S. FDA for oral use
• Synthetic progestins
– C-21 class (e.g., medroxyprogesterone acetate) • e.g., Megestrol®, Provera®
– 19-nortestosterone class (e.g., norethindrone acetate) • e.g., Micronor®, Norlutate®
Progestogen Indications
• Primary menopause-related indication is endometrial protection from unopposed ET
• Not necessary with standard doses of vaginal ET (including vaginal ring)
• Progestogen not generally indicated with ET post-hysterectomy
Estrogen and progestogen use in postmenopausal women: 2010 position statement of The North American Menopause Society. Menopause 2010;17(2):242-55.
Micronized Progesterone Metabolism
• Metabolized primarily by the liver
• Metabolites act at non-sex-steroid receptor sites
• Beneficial effects of metabolites – Sedation effect with higher doses of oral progesterone
– Has anti- aldosterone properties
• May reduce bloating, breast tenderness and edema
• Adverse effects of metabolites – May cause nausea and dizziness
– Contraindicated in patients with peanut allergy
Case Study # 5
• 52 years old, 2 years postmenopausal. Currently experiencing severe VMS, sleep deprivation, decreased libido and sexual response, and dyspareunia.
• Has experimented with black cohosh with no success. Trials of clonidine and venlafaxine also resulted in a poor response.
• Patient is interested in trying HT but does not wish to experience BTB and has family hx of breast cancer
• She currently smokes 1/2 pack per day.

GUIDELINE RECOMMENDATIONS FOR THE MANAGEMENT OF MENOPAUSAL
SYMPTOMS
NAMS Position Statement 2010
• Estrogen Therapy, with or without a progestogen, is the most effective treatment for menopausal-related vasomotor symptoms
• Individualization of therapy is key
• Low absolute risk potential for Hormone Therapy
“ Growing body of evidence that each type of estrogen and progestogen, route of administration and timing of therapy
has distinct beneficial and adverse effects.”
• Further research essential
Estrogen and progestogen use in postmenopausal women: 2010 position statement of The North American Menopause Society. Menopause 2010;17(2):242-55.
SOGC Consensus Recommendations 2009 Update
• Menopause is a major life transition with opportunity for healthy interventions
• Patient concerns may be related to aging as well as menopause specific
• Primary indication for HT: – Management of moderate to severe menopausal symptoms
(Grade A)

Endocrine Society Scientific Statement on HT
• Overall mortality: Menopausal HT (MHT) was associated with a 40% reduction in mortality in trials in which participants had a mean age below 60 yr or were within 10 yr of menopause onset.
• Standard-dose oral MHT may increase stroke risk by about 1/3 in generally healthy postmenopausal women.
• Transdermal estrogen does not increase venothrombotic episode risk.
• Micronized progesterone in combination with estrogen does not increase breast cancer risk if given for 5 years or less.

The Medical Letter Position BHT
“There is no acceptable evidence that “bioidentical” (custom-compounded)
hormones are safe or effective.
Patients should be discouraged
from taking them.”

Summary
• Primary purpose for prescribing HT remains symptomatic relief
• Transdermal estrogens are considered part of the armamentarium of HT
– May offer certain benefits in specific clinical scenarios
• Micronized progesterone may also offer benefits in bleeding patterns and reduced risk of breast cancer compared to MPA
• Evidence-based recommendations for management of menopausal symptoms can help guide optimal treatment decisions

*Adjusted for age, body-mass index, parity, educational level and time-period.
Progestogens
• Any substance that has progestational activity
• Includes “natural” and “bioidentical” progesterone and synthetic progestins
• Progestins are synthetic progestogens with biologic activity to progesterone
• Oral progesterone is broken down in GI tract and therefore is inactive
• Progestins were developed which are not broken down in the GI tract; derived from progesterone or testosterone (19-nortestosterone) precursors
• Once micronization was discovered, progesterone could be given orally
Progestogen Selection
Two different classes of progestogens are used in HT:
1. 17-hydroxyprogesterone (norpregnane) derivatives (including medroxyprogesterone acetate [MPA], megestrol, and progesterone)
2. 19-nortestosterone derivatives (norethindrone and norethindrone acetate)
