Osaterone acetate (previously known as TZP-4238), a synthetic steroidal anti-androgen agent. Osaterone acetate is used in veterinary in Europe in the treatment of benign prostatic hyperplasia (BPH) in male dogs. Osaterone acetate inhibits the effects of an excess of male hormone (testosterone) through various mechanisms. It competitively prevents the binding of androgens to their prostatic receptors and blocks the transport of testosterone into the prostate. Osaterone acetate was also investigated in Japan in the treatment of prostate cancer and BPH and, in addition, was studied in postmenopausal osteoporosis in humans. However, these studies were discontinued.
