Used primarily in the treatment of prostate cancer, this compound acts as an antiandrogen that blocks the effects of androgens like testosterone in the body. It is commonly prescribed in combination with a gonadotropin-releasing hormone (GnRH) analog for patients with metastatic prostate cancer. By inhibiting androgen receptor signaling, it helps slow the growth and spread of cancer cells in the prostate. Its enantiomeric form ensures higher specificity and reduced side effects compared to the racemic mixture. It is also investigated for use in conditions involving androgen excess, such as certain hormone-dependent disorders in men and women.
