<p>This contains two active ingredients- Ethinylestradiol and Drospirenone. Ethinylestradiol is a synthetic version of estrogen and Drospirenone is a synthetic form of progesterone. The hormonal components of this preparation inhibit ovulation by suppressing gonadotropin release. Secondary mechanisms, which may contribute to the effectiveness of this tablet as a contraceptive, include changes in the cervical mucus (which increase the difficulty of sperm penetration) and changes in the endometrium (which reduce the likelihood of implantation).<br />

Drospirenone has antimineralocorticoid activity, counteracting estrogen-related sodium retention. In combination with Ethinyloestradiol, Drospirenone displays a favorable lipid profile with an increase in high-density lipoprotein HDL. Drospirenone exerts antiandrogenic activity and does not counteract the ethinyloestradiol-related sex hormone-binding globulin increase which is useful for binding and inactivating the endogenous androgens.</p>
