Abstract
Hormone therapy classically consists of an estrogen with an added progestin; however, concerns have been raised about the potential negative effects of progestin. The recent realization that estrogen agonist-antagonists or selective estrogen receptor modulators might be paired with estrogens instead of a progestin has led to the development of a novel form of menopausal therapy called tissue selective estrogen complex (TSEC). A TSEC is the pairing of a selective estrogen receptor modulator (SERM) with estrogen(s). The TSEC containing conjugated estrogens (CE) and the SERM, bazedoxifene (BZA), has reached clinical development. This short review outlines the effects of this particular TSEC, which maintains or increases bone mass in women at high risk for osteoporosis, and has clinical qualities of a promising new menopausal therapy. Randomized, double-blind, placebo-controlled phase 3 trials in postmenopausal women showed that, in addition to bone preservation, BZA/CE was shown to relieve hot flushes and treat vulvar-vaginal atrophy and its symptoms, with a good safety and tolerability profile.
