Bio-identical Hormones
• Hormones that are identical to those produced in the human body (may be synthetically produced)– Estrone, estradiol, estriol (Ortho-
Est,Estrace, Estraderm, Climara)– Progesterone (ProGest, Fem-Gest,
Progonol)– Testosterone– DHEA
Natural Progesterones?Compounding Pharmacies
• Mexican Wild Yam• (Must add UPS Progesterone to topical
cream to be bioavailable)
• Compounding pharmacies: Bi-Est, Tri-Est, Micronized Progesterone
• 800-927-4227; www.iacprx.com… • www.womensinternational.com…
Ovarian Steroidogenesis
Altered and“Natural Hormones”
• Conjugated or otherwise modified from the original structure
• May have multiple components, bioactivity, bioavailability, metabolites
• Premarin®, conjugated equine estrogen has 90 different hormonal components
Differences in Function/Structure

Basics of Menopausal Care
• Regular exercise• Social support• Meditation, relaxation, sleep • Quit smoking/alcohol• Dietary phytoestrogens
– Soy– Celery, fennel, parsley– Nuts, seeds– Flaxseed
Phytoestrogens
• Soy• Black Cohosh
• Dong Quai• Red Clover• Chaste Berry Tree• Licorice• Evening Primrose Oil• Ginseng
Botanicals
• Cimcifuga racemosa (Black cohosh) 1-2 g tid; 2 mg bid (27-deoxyacteine)
• Angelica sinensis (Dong quai) 1-2 g tid• Glycyrrhiza glabra (Licorice) 1-2 g tid• Vitex agnus-castus (Chaste berry)1-2
g tid• Ginseng 500-1000 mg/d
Conclusions
• Jury still out on safety of HRT
• Bio-identical HRT has not been evaluated in clinical trials
• Are risks of HRT due to the hormones, their metabolites, methods of administration
Conclusions
• Botanical medicines useful to treat menopausal sx
• ? Effect on osteoporosis, CV dz
• Progesterone alone may tx both menopausal sx and osteoporosis (controversial for osteoporosis when used alone)
BOTTOM LINE
– HRT for menopausal sx is likely safe for up to 4-5 yrs
– Longer use (10-15 yrs) may create increased risk for some women
– Don’t HRT as CV tx or preventive– Individualize risk/benefit ratio and choice for
each pt.
