Description
Xtandi 40 mg Tablet contains enzalutamide, an oral anticancer medicine classified as an androgen receptor inhibitor. It is used in the treatment of prostate cancer, particularly in cases where the disease has spread beyond the prostate or continues to progress despite reduced testosterone levels. Prostate cancer cells often depend on male hormones called androgens (such as testosterone) to grow. Enzalutamide works by blocking the activity of these hormones in cancer cells. Xtandi interferes with the androgen receptor signaling pathway by preventing androgens from binding to their receptors and by inhibiting the movement of these receptors into the cell nucleus where they activate genes responsible for tumor growth. By disrupting this process, the medicine may help slow the progression of prostate cancer when taken as prescribed by a qualified healthcare professional. Xtandi tablets are t
Benefits
-
Blocks androgen receptor signaling, a key driver of prostate cancer growth
-
Oral targeted therapy suitable for outpatient treatment
-
Used in various stages of advanced prostate cancer

-
Part of modern hormone therapy approaches for prostate cancer
Indications and Usage
Xtandi (enzalutamide) may be prescribed for:

-
Metastatic hormone-sensitive prostate cancer (mHSPC)
-
Patients undergoing androgen deprivation therapy (ADT) for prostate cancer
Treatment decisions are based on disease stage, prior therapies, and clinical evaluation.
How it Works
Enzalutamide works by inhibiting the androgen receptor signaling pathway, which plays a central role in the development and progression of prostate cancer. Androgens such as testosterone normally bind to androgen receptors in prostate cells and activate genes that promote cell growth.
Xtandi blocks this process in several ways. It prevents androgens from binding to the receptor, inhibits the receptor’s movement into the cell nucleus, and interferes with its ability to activate growth-related genes. By disrupting these signals, enzalutamide helps reduce cancer cell growth and slow disease progression when used as prescribed and monitored by a healthcare professional.
