Enzalutamide 40 mg tablets are used to treat advanced prostate cancer, specifically metastatic castration-resistant prostate cancer. Enzalutamide is an androgen receptor inhibitor that acts by disrupting the interaction between testosterone and cancer cells, limiting their growth and spread. It is available in 40 mg capsules and film-coated tablets for oral use. The medicine has been proven to enhance metastasis-free and overall survival rates in prostate cancer patients. Enzalutamide is also licensed for the treatment of metastatic prostate cancer, however it has a higher risk. It is frequently used in combination with other medicines, such as leuprolide, to treat prostate cancer. Side effects of enzalutamide include hot flushes, exhaustion, and muscle.
