  • Chronic Unopposed Vaginal Estrogen Therapy
    October, 1999. The Rx Files: Q&A Summary S. Downey BSP, L.D. Regier BSP, BA Chronic Unopposed Vaginal Estrogen Therapy The question of whether progestagen opposition is required in a patient on chronic vaginal estrogen is controversial. The literature is not clear on this matter and the SOGC conference on Menopause did not reach a consensus. Endometrial hyperplasia is directly related to the dose and duration of estrogen therapy. The PEPI study showed that 10 per cent of women taking unopposed estrogen (equivalent to 0.625 mg CEE) will develop complex or atypical endometrial hyperplasia within 1 year. With long-term HRT, it is now considered standard practice to add progestagen opposition to oral estrogen therapy in women with an intact uterus. The case is less clear for vaginal estrogen therapy. The makers of Premarinâ vaginal cream indicate their product is for short term management of urogenital symptoms and the monograph clearly states "precautions recommended with oral estrogen administration should also be observed with this route". In one recent study looking at "Serum and tissue hormone levels of vaginally and orally administered estradiol" (Am J Obstet Gynecol 1999;180:1480-3), serum levels were 10 times higher after vaginal vs. oral administration for exactly the same dose while endometrial concentrations were 70 times higher. This suggests that in some cases very little estrogen is required vaginally to produce significant serum levels and there may be preferential absorption into the endometrium. Hence equivalent vaginal doses may sometimes be much lower on a mg per mg basis compared to oral, largely because of bypassing the "first pass" effect.

    Ospemifene Monograph Ospemifene (OSPHENA) National Drug Monograph October 2015 VA Pharmacy Benefits Management Services, Medical Advisory Panel, and VISN Pharmacist Executives The purpose of VA PBM Services drug monographs is to provide a comprehensive drug review for making formulary decisions. Updates will be made when new clinical data warrant additional formulary discussion. Documents will be placed in the Archive section when the information is deemed to be no longer current. FDA Approval Information Description/Mechanism of Ospemifene is a selective estrogen receptor modulator (SERM) with agonist Action actions on vaginal tissue, the endometrium and bone. Antagonist actions suggest antitumor effects in experimental breast cancer models. Ospemifene is not interchangeable with other SERMs such as raloxifene or tamoxifen, nor they with it.

  • Vaginal Dryness
    Vaginal Dryness Bothersome symptoms of the vagina and vulva (outer lips of the vagina) increase during and after the menopause transition or may start several years after menopause. The decrease in estrogen with menopause is a major contributor to vaginal dryness, itching, burning, discomfort, and pain during intercourse or other sexual activity. Vaginal atrophy is the medical term that describes these changes. The genitourinary syndrome of menopause includes bothersome vaginal atrophy often combined with urinary symptoms. Vaginal atrophy may significantly affect your quality of life, sexual satisfaction, and relationship with your partner. Unlike hot flashes, which generally improve with time, vaginal symptoms typically worsen with time because of aging and a prolonged lack of estrogen. Menopause and aging can affect the vagina in the following ways: Vaginal tissues become thin, dry, and less elastic, with decreased secretions and lubrication Vaginal infections increase (as the healthy acidic pH of the vagina becomes more alkaline) Discomfort with urination and increased urinary tract infections can occur Fragile, dry, inflamed vaginal tissues may tear and bleed Women with menopause induced by cancer treatments may have additional injury to the vaginal tissues from chemotherapy or pelvic radiation Aromatase inhibitors, taken by many women with breast cancer, result in extremely low estrogen levels, often causing severe symptoms of vaginal dryness and decreased lubrication Vaginal changes often result in pain with sexual activity

  • 2017 Hormone Therapy Position Statement of the North American Menopause Society
    Menopause: The Journal of The North American Menopause Society Vol. 24, No. 7, pp. 728-753 DOI: 10.1097/GME.0000000000000921 ß 2017 by The North American Menopause Society POSITION STATEMENT The 2017 hormone therapy position statement of The North American Menopause Society Abstract The 2017 Hormone Therapy Position Statement of The North American Menopause Society (NAMS) updates the 2012 Hormone Therapy Position Statement of The North American Menopause Society and identifies future research needs. An Advisory Panel of clinicians and researchers expert in the field of women’s health and menopause was recruited by NAMS to review the 2012 Position Statement, evaluate new literature, assess the evidence, and reach consensus on recommendations, using the level of evidence to identify the strength of recommendations and the quality of the evidence. The Panel’s recommendations were reviewed and approved by the NAMS Board of Trustees. Hormone therapy (HT) remains the most effective treatment for vasomotor symptoms (VMS) and the genito- urinary syndrome of menopause (GSM) and has been shown to prevent bone loss and fracture. The risks of HT differ depending on type, dose, duration of use, route of administration, timing of initiation, and whether a progestogen is used. Treatment should be individualized to identify the most appropriate HT type, dose, formulation, route of administration, and duration of use, using the best available evidence to maximize benefits and minimize risks, with periodic reevaluation of the benefits and risks of continuing or discontinuing HT. For women aged younger than 60 years or who are within 10 years of menopause onset and have no contraindications, the benefit-risk ratio is most favorable for treatment of bothersome VMS and for those at elevated risk for bone loss or fracture.
