Description

Drospirenone is a synthetic progestin that is an analog to spironolactone. It is found in a number of 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. It was shown in animal studies that drospirenone exhibits antiandrogenic activity judging from accessory sex gland growth in castrated, androgen-treated, juvenile rats.

IndicationFor the prevention of pregnancy in women who elect an oral contraceptive.
PharmacodynamicsDrospirenone 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.
Mechanism of actionProgestins such as drospirenone diffuse freely into target cells in the female reproductive tract, mammary gland, hypothalamus, and the pituitary and bind to the progesterone receptor. Once bound to the receptor, progestins slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH surge.
AbsorptionOral bioavailability is approximately 76%.
Volume of distributionNot Available
Protein binding95-97%
Metabolism

Extensively metabolized following oral or intravenous administration. The two major metabolites are inactive and are formed independent of the CYP450 enzyme system. The metabolites are the acid form of drospirenone formed by opening of the lactone ring and the 4,5-dihydro-drospirenone-3-sulfate.

Drug
ArtemetherArtemether may decrease the effectiveness of drospirinone by increasing its metabolism via CYP3A4. Consider an alternate non-hormonal means of contraception during artemether therapy.
BenazeprilIncreased risk of hyperkalemia
BexaroteneBexarotene may decrease the serum concentration of Contraceptives (Progestins). Since bexarotene is teratogenic and can lower serum concentrations of drospirenone, it is advised that women of childbearing potential use two forms of contraception (including at least one non-hormonal form).
BoceprevirBoceprevir increases levels by affecting CYP3A4 metabolism. Concomitant therapy is contraindicated.
CandesartanIncreased risk of hyperkalemia
CaptoprilIncreased risk of hyperkalemia
CilazaprilIncreased risk of hyperkalemia
ColesevelamBile Acid Sequestrants may decrease the serum concentration of Contraceptives (Progestins). Administer oral progestin-containing contraceptives at least 1-4 hours prior to or 4-6 hours after administration of a bile acid sequestrant. Consider alternatives in order to avoid this combination when possible, due to the risk for impaired contraceptive effectiveness.
EnalaprilIncreased risk of hyperkalemia
EprosartanIncreased risk of hyperkalemia
FosinoprilIncreased risk of hyperkalemia
HeparinHeparin can increase risk of hyperkalemia for patients on drospirenone
IrbesartanIncreased risk of hyperkalemia
LisinoprilIncreased risk of hyperkalemia
LosartanIncreased risk of hyperkalemia
OlmesartanIncreased risk of hyperkalemia
PerindoprilIncreased risk of hyperkalemia
PotassiumIncreased risk of hyperkalemia
QuinaprilIncreased risk of hyperkalemia
RamiprilIncreased risk of hyperkalemia
TelmisartanTelmisartan may increase the hyperkalemic effect of Drospirenone. Monitor for increased serum potassium concentrations during concomitant therapy.
ThiopentalThiopental may decrease the effect of Drospirenone. Contraceptive failure may occur. Alternative nonhomomonal contraception should be used during concomitant therapy.
TrandolaprilIncreased risk of hyperkalemia. Monitor serum potassium levels.
TreprostinilAdditive hypotensive effect. Monitor antihypertensive therapy during concomitant use.
TretinoinOral Tretinoin may decrease the effect of oral contraceptive, Drospirenone. An alternate form of contraception should be used during concomitant therapy.
TriamtereneIncreased risk of hyperkalemia
WarfarinDrospirenone may alter the anticoagulant effect of warfarin. Concomitant therapy should be avoided. Monitor for changes in coagulation status if drospirenone is initiated, discontinued or dose changed.

  • Food reduces the rate of absorption, but not the extent of absorption.
