Information

Norgestrel and ethinylestradiol is a combination oral contraceptive containing a synthetic progestin (norgestrel) and a synthetic estrogen (ethinylestradiol), primarily used for the prevention of pregnancy. This combination is approved and widely used globally for birth control purposes. It may also be used for menstrual regulation in women.

Pharmacokinetics

Pharmacokinetic parameters reflect healthy adult female volunteers, typically of reproductive age, after administration of a single oral dose corresponding to a standard tablet (norgestrel 0.3 mg and ethinylestradiol 0.03 mg).
