Melatonin is a hormone synthesized in the pineal gland from tryptophan. It participates in several biological processes in the human being, such as circadian sleep rhythm, mood, reproductive processes and aging. Melatonin serum levels are increased in childhood and diminish importantly in older people. Serum levels are diminished in patients with insomnia and depressive mood. Experimentally, the melatonin inhibits the growth of mammary tumors in animals. With respect to endometrial cancer and Alzheimer's disease, the information is not conclusive. No changes have been found in melatonin levels in climacterical women. So its use has not fundament in postmenopausal women, however it can only be administered for short periods of time for the treatment of some sleep disturbances.

Hormone replacement therapy (HRT) with estrogens (in non-hysterectomized women with estrogens and progestins) during the peri- and postmenopausal period has been widely applied for many years. On the basis of new data, HRT is currently being critically reviewed. HRT administered for up to 5 years to treat climacteric hot flashes, mood changes and sleep disturbances continues to be advocated and is largely safe. When HRT is used for longer periods, as required for the prevention of osteoporosis, a possible increase in the relative risk for breast cancer must be considered. Correctly applied in combination with an adequate dose of progestins, HRT can avoid an increase in the endometrial cancer risk. HRT is no longer recommended for secondary prevention of cardiovascular disease, and its use in primary prevention has not been convincingly demonstrated. The hoped-for efficacy of HRT in the prevention of Alzheimer's disease has not been confirmed by the data. Selective estrogen receptor modulators (e.g. Raloxifene) and biphosphonates are efficacious drugs for the prevention and treatment of osteoporosis. For women at risk of developing cardiovascular disease, changes in lifestyle, lipid-lowering drugs (statins), blood pressure control, use of acetylsalicylic acid, among others, have well-documented efficacy in primary and secondary prevention.

This statement summarizes the U.S. Preventive Services Task Force (USPSTF) recommendations for use of hormone replacement therapy for the primary prevention of chronic conditions in postmenopausal women and updates the 1996 USPSTF recommendations on this topic. The complete information on which this statement is based, including evidence tables and references, is available through the USPSTF Web site (http://www.preventiveservices.ahrq.gov) and through the National Guideline Clearinghouse (http://www.guideline.gov) The USPSTF reviewed the evidence on the use of postmenopausal hormone replacement therapy and the following outcomes: cardiovascular disease, including CHD and stroke; osteoporosis and fractures; thromboembolism; dementia and cognitive function; breast, colon, ovarian, and endometrial cancer; and cholecystitis. The USPSTF also reviewed evidence of the effects of hormone replacement therapy on phytoestrogens and osteoporosis and cardiovascular disease. The use of hormone replacement therapy for relieving active symptoms of menopause, such as hot flashes, urogenital symptoms, and mood and sleep disturbances, among others, is outside the scope of these USPSTF recommendations, and literature on this topic was not reviewed. Sources for estimates of benefits and harms cited in this Recommendation statement are described in the summary of the evidence available from the Agency for Healthcare Research and Quality.
