Abstract

Introduction: The recent concept that estrogen agonist-antagonists, often referred to as selective estrogen receptor modulators, can be combined with an estrogen has led to the development of a novel form of menopausal therapy called Tissue-Selective Estrogen Complex (TSEC). This paper reviews the TSEC bazedoxifene and conjugated equine estrogens (BZA/CE). Areas covered: This review is based on clinical trials and a PubMed search. The pharmacokinetics and pharmacodynamics of BZA in BZA plus CE are reviewed. This review outlines the effects of this particular TSEC, which maintains or increases bone mineral density in women at high risk for osteoporosis, and has clinical qualities of a promising new menopausal therapy. The potential adverse effects of BZA/CE combinations are summarized. Expert opinion: A TSEC that contains CE and BZA that has both estrogen agonist and antagonist effects has reached clinical development. Phase III clinical trials show this TSEC relieves hot flashes, improves vulvo-vaginal atrophy and its symptoms, does not stimulate the endometrium, and prevents bone loss. In the trials so far it appears to have a good safety and tolerability profile. The optimum combination of BZA/CE combination is 20 mg BZA with CE 0.45 and 0.625 mg daily.
