ZYTIGA® (abiraterone acetate) Blocks Androgen Production at 3 Sources — the Testes, the Adrenal Glands, and the Tumor Itself.
ZYTIGA® works by interrupting the androgen-making process at an important step thereby reducing the amount of androgen being made.
The Role of Androgen
The male body produces male hormones called androgens. Research has shown that androgens help feed the tumor. Androgens, such as testosterone, are primarily made by your testes and your adrenal glands. However, in men with CRPC, androgen is also made by an additional source — the tumor itself.
Reducing the production of androgen is key to helping you and your doctor manage your illness because even a small amount of androgen may activate the tumor.
