Introduction:

· Drospirenone is an ingredient in some birth control pills and hormone replacement therapy. In combination with ethinyl estradiol it is used ascontraception, and for women who want contraception it is also approved by the U.S. Food and Drug Administration (FDA) to treat moderate acne andpremenstrual dysphoric disorder.

· Drospirenone has anti-androgenic effects in addition, it also has the effect of salt corticosteroids, to prevent water and sodium retention in the body. Not only has excellent contraceptive effectiveness, but also on women's health has many positive effects. Such as to reduce acne and make skin more smooth and effective control of body weight.

· Function&usage:

· Drospirenone is taken orally with about 76% bioavailability. It is bound by other serum proteins. Metabolites have not been shown to be biologically active, show up in urine and feces, and are essentially completely excreted within 10 days.

· The compound differs from other synthetic progestins in that its pharmacological profile in preclinical studies shows it to be closer to the natural progesterone. As such it has anti-mineralocorticoid properties, counteracts the estrogen-stimulated activity of the renin-angiotensin-aldosterone system, and is not androgenic. The anti-aldosterone properties exhibited by drospirenone promote sodium excretion and prevent water retention
