TA XBIRA 250MG TAB (120S)

Abiraterone acetate 250MG Tablet's primary mechanism of action involves potent and selective inhibition of CYP17A1, an enzyme crucial for androgen biosynthesis. By blocking CYP17A1, the medication suppresses the production of androgens in various tissues, including the testes, adrenal glands, and prostate tumor cells. This inhibition leads to a significant reduction in circulating testosterone and other androgens, which are essential for the growth and survival of prostate cancer cells. Abiraterone acetate specifically targets the conversion of precursor hormones, such as pregnenolone and progesterone, into androgens, thereby disrupting the androgen signaling pathway and inducing apoptosis in androgen-dependent prostate cancer cells.
