the Drospirenone

Drospirenone and Ethinyl Estradiol is a type of birth control pill that combines two hormones: the lowest dosage of ethinyl estradiol commonly used today and drospirenone, a different type of progestin. Drospirenone is a compound closely resembling progesterone, but has properties that are closely related to spironolactone, a diuretic drug used to treat high blood pressure. Drospirenone and Ethinyl Estradiol was approved by the Food and Drug Administration on May 11, 2001.
Drospirenone is part of certain birth control formulations. 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 anti-mineralocorticoid properties, counteracts the estrogen-stimulated activity of the renin-angiotensin-aldosterone system, and is not androgenic.
Drospirenone is highly potent active pharmaceutical ingredients, belongs to the hormone contraceptive and replacement therapy group of drugs. These drugs are highly potent active pharmaceutical ingredients that need special handle in production or preparation.
