Enzalutamide (Xtandi) 40 mg Capsules

Xtandi 40 mg Capsule

Xtandi 40 mg Capsule is a drug for the treatment of advanced prostate cancer. Xtandi is used to treat metastatic, castration-resistant prostate cancer that does not respond to surgical or drug therapy to lower testosterone levels.

The main active ingredient of the drug is Enzalutamide 40 mg Capsule, a synthetic non-steroidal anti-androgen that blocks the body’s ability to use any sex hormones.

Principle of operation of Xtandi (Enzalutamide) 40 mg Capsule

Prostate cancer forms in the gland of the male reproductive system, which is located below the bladder and in front of the rectum. The cells of the prostate gland have receptors that bind to androgens – male sex hormones that help these cells grow. In the event of a tumor, its growth is stimulated by the main male sex hormone – testosterone, as well as related hormones.

By reducing the amount of androgens, it is possible to shrink and slow down cancer growth. Xtandi 40 mg is an anti-androgen drug that works by preventing the action of sex hormones, including testosterone, and inhibiting the growth of prostate cancer cells.
