Drospirenone for oral contraception and hormone replacement therapy: are its cardiovascular risks and benefits the same as other progestogens?

The use of combined estrogen/progesterone has been shown to result in an increased cardiovascular risk in randomised double-blinded trials. However, these studies used oral progestogen (progestin) preparations, which lack anti-mineralocorticoid activity and have suboptimal anti-androgenic activity compared with progesterone. Drospirenone is a unique progestogen that has clinically been shown to have anti-mineralocorticoid/anti-androgenic effects. Drospirenone in combination with estrogen is currently being used for oral contraception and hormone replacement therapy, and has been shown to have favourable effects on a number of cardiovascular risk factors. Our review of the literature suggests that because of its anti-mineralocorticoid effects, drospirenone in conjunction with estrogen may prevent the development of cardiovascular disease in both pre- and post-menopausal women.
