Drospirenone (INN, USAN), also known as 1, 2-dihydrospirorenone, is a synthetic hormone used in birth control pills and postmenopausal hormone replacement therapy pills.
It is sold under the brand names Yasmin, Yasminelle, Yaz, Beyaz, Ocella, Zarah, Daylette and Angeliq, all of which arecombination products of drospirenone with an estrogen such as ethinylestradiol or estradiol.
Drospirenone 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 potent antimineralocorticoid properties, counteracts the estrogen-stimulated activity of the renin-angiotensin-aldosterone system, and has also been shown to possess mild antiandrogen activity.
The antimineralocorticoid properties exhibited by drospirenone promote sodium excretion and prevent water retention.

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