Indenza, containing Enzalutamide as the active ingredient, is an oral medication used to treat certain types of prostate cancer. It is classified as an androgen receptor inhibitor and works by blocking the effects of androgens (male hormones) that promote the growth of cancer cells.

Uses:

1. Metastatic castration-resistant prostate cancer (mCRPC).
2. Non-metastatic castration-resistant prostate cancer (nmCRPC).
3. Metastatic hormone-sensitive prostate cancer (mHSPC).

Enzalutamide binds to androgen receptors on prostate cancer cells, preventing androgens like testosterone from activating these receptors. This inhibits the growth and survival of prostate cancer cells.
