Flutamide is primarily used in the treatment of prostate cancer. It works by blocking the effects of androgens (male hormones) on the prostate gland, thereby slowing the growth and spread of cancer cells. It is often prescribed in combination with other medications, such as luteinizing hormone-releasing hormone (LHRH) analogs, to enhance its effectiveness. Additionally, Flutamide has been explored in the management of hirsutism (excessive hair growth) in women with polycystic ovary syndrome (PCOS), helping to reduce symptoms by lowering androgen levels. Its role in these conditions highlights its significance in hormonal regulation and cancer therapy.
