Medroxyprogesterone and ethinylestradiol is a combined oral contraceptive containing the progestin medroxyprogesterone acetate and the estrogen ethinylestradiol. This combination was previously used for hormonal contraception and regulation of menstrual disorders. Currently, it is not widely used or approved in most countries, having been largely replaced by other contraceptive combinations.
Pharmacokinetics
Estimated pharmacokinetic parameters for healthy adult women based on published pharmacokinetics of individual components (medroxyprogesterone acetate and ethinylestradiol) as no specific studies of the combination were identified.
