Primarily used in the treatment of prostate cancer, it combines the effects of an alkylating agent with a hormone therapy component. This dual-action mechanism allows it to target cancer cells more effectively by disrupting DNA function and interfering with androgen activity, which is crucial for the growth of prostate cancer cells. It is often prescribed for patients with advanced stages of the disease, particularly when other treatments have proven ineffective. Additionally, it may be used in combination with other therapies to enhance its efficacy. Its unique structure enables it to deliver cytotoxic effects while also reducing the influence of male hormones that fuel cancer progression.
