Ahabir is a brand of Abiraterone Acetate, an anticancer medication primarily used to treat prostate cancer. Abiraterone Acetate works by inhibiting the production of androgens (male hormones) that fuel the growth of prostate cancer cells. By blocking the enzyme CYP17A1, which plays a key role in the production of androgens, Ahabir effectively reduces the levels of testosterone and other hormones that can stimulate the growth of prostate cancer.
