What Is Darolutamide?
Darolutamide, sold under the brand name Nubeqa, is a hormone therapy medication used to treat prostate cancer. It is typically prescribed in combination with other cancer treatments, depending on the stage and progression of the disease.
When Is Darolutamide Used?
- For non-metastatic castration-resistant prostate cancer (nmCRPC) – When cancer has not spread beyond the prostate but continues to grow despite low testosterone levels.
- For metastatic hormone-sensitive prostate cancer (mHSPC) – When cancer has spread to other parts of the body, often combined with chemotherapy or other hormone therapies.
Pronunciation Guide
Darolutamide is pronounced as “dar-oh-LOO-ta-mide.”
How Does Darolutamide Work?
Prostate cancer cells rely on testosterone (a male hormone) to grow and multiply.
- Testosterone Production: Most testosterone is made in the testicles, with a small amount produced by the adrenal glands.
- Mechanism of Action: Darolutamide is an androgen receptor inhibitor, meaning it blocks testosterone from reaching cancer cells, slowing down tumor growth.
