Xtandi - 40mg



Xtandi, also known by its generic name enzalutamide, is a prescription medicine primarily utilized for the treatment of advanced prostate cancer. This type of cancer often becomes resistant to traditional hormone therapy, leading to the need for alternative solutions. Xtandi belongs to a class of drugs called androgen receptor inhibitors, and it operates by targeting and inhibiting the action of androgens, which are male hormones that fuel the growth of prostate cancer cells.

This medication is specifically designed to address cases of metastatic castration-resistant prostate cancer (mCRPC). This advanced form of cancer occurs when cancer cells continue to grow even in the absence of testosterone, a hormone typically suppressed in prostate cancer treatment. Xtandi offers hope to individuals facing mCRPC, providing them with an effective means of managing the disease’s progression.

The mechanism behind Xtandi’s effectiveness lies in its ability to interfere with the androgen signaling pathway. Prostate cancer cells thrive on androgens, which stimulate their growth. Xtandi works by binding to the androgen receptors on these cells, preventing androgens from attaching and thereby inhibiting the signals that drive cancer cell growth. This targeted approach curtails the cancer’s ability to spread and helps manage its progression.


It is important to inform your doctor or pharmacist if you have any allergies to enzalutamide.There is a possibility that this product may contain inactive ingredients that can cause allergic reactions or other problems.

Your doctor or pharmacist should be informed of your medical history before taking this medication, particularly if you have high blood pressure, seizures, or risk factors for seizures (such as brain injuries, strokes, brain tumors), heart disease (such as angina/chest pain, heart attack), diabetes, high cholesterol, high triglycerides in your blood, falls, or broken bones.

Due to the possibility that this medication may rarely trigger seizures in some individuals, ask your doctor if you should avoid activities that could result in a sudden loss of consciousness.

A man who has a pregnant partner should use a condom during and after treatment with enzalutamide. Men with a female partner of childbearing age who is not expecting a child should use a condom and another form of birth control during enzalutamide treatment. This should be done for 3 months after treatment stops. Ask your doctor for more details. If your partner becomes pregnant or thinks she may be so, tell your doctor right away.
