Bicalutamide is primarily used in the treatment of prostate cancer. It functions as an anti-androgen, effectively blocking the action of male hormones like testosterone, which can stimulate the growth of prostate cancer cells. Typically, it is prescribed in combination with other therapies, such as luteinizing hormone-releasing hormone (LHRH) analogs, to enhance its effectiveness. This combination helps in reducing testosterone levels in the body, thereby slowing the progression of the cancer. Bicalutamide is often utilized in both early and advanced stages of prostate cancer, providing a therapeutic option for patients who may not be suitable candidates for surgical interventions. Its oral administration offers convenience, making it a preferred choice in long-term treatment regimens.
