ABSTRACT

Views and clinical practice on hormone replacement therapy (HRT) for postmenopausal women have varied widely over the last several decades. The 1990s showed a dramatic decline in prescribing and only recently are prescription rates increasing again. Use of HRT is first line for women suffering from the symptoms of menopause. For a certain population of postmenopausal women, HRT is recommended for prevention of fracture. More consideration is being given to patient risk factors, side effects, and formulations available. Transdermal patch estrogen formulations have been on the market for many years and are becoming more common although many physicians are less familiar with the various options. Transdermal preparations are worth consideration with regard to less adverse effects as there is the avoidance of liver metabolism and accumulation of metabolites with antiestrogenic activity. Data suggests that transdermal patch estrogen preparations are both safer and potentially more efficacious than oral estrogen therapy. Guidelines recommend the addition of progesterone for women who have not had a hysterectomy. Transdermal patch estrogen has a role for women as a choice for individualized therapy and providers need to be familiar with the formulations as well as unique challenges and advantages.
