For Prostate Cancer and Over-active Sex Drive in Men

Androstat® tablets, made with cyproterone acetate; an antiandrogen, is Pacific Pharmaceutical’s special product to curb over-active sex drive and treat prostate cancer in men.


Active Ingredients

Cyproterone acetate: Cyproterone acetate belongs to the group of medications called antiandrogens. It is used for the treatment of prostate cancer but with a combination of estrogen, it can also be used to treat gynecological conditions in women related to androgen sensitivity, such as acne.

Mechanism of Action

Androgen are a group of hormones responsible for male traits and reproductive activity. They are also called the ‘male hormones.’ The growth of tumors of the prostate gland may be dependent on the male hormones.  The antiadrogenic properties block the androgen receptors which help in reducing the androgen levels in the body and relieve the symptoms of the tumor in the prostate gland.

Androstat® can also be used by males to control an over active sex drive.
