Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination oral contraceptive: ethinyl estradiol and norgestrel inhibit ovulation via suppression of gonadotropins (LH, FSH); increase viscosity of cervical mucus, impairing sperm penetration; alter endometrial structure, reducing implantation likelihood.
Combination of drospirenone, a spironolactone analog with antimineralocorticoid and antiandrogenic activity, and ethinyl estradiol, an estrogen. Suppresses gonadotropins, primarily luteinizing hormone, inhibiting ovulation. Increases cervical mucus viscosity and alters endometrial receptivity.
One tablet (norgestrel 0.3 mg/ethinyl estradiol 30 mcg) orally once daily at the same time each day for 28 days, with 21 active tablets followed by 7 inactive tablets.
One capsule orally once daily for 24 weeks.

Norgestrel: ~45 hours (terminal). Ethinyl estradiol: ~13 hours (terminal). Steady-state achieved within 5-7 days.
Terminal elimination half-life: 30 hours. Provides once-daily dosing with steady-state achieved after 7 days.
Renal 50-60% as metabolites, fecal 40-50% via biliary elimination. Ethinyl estradiol undergoes enterohepatic recirculation.
Renal: ~60% as unchanged drug; Fecal: ~40% as metabolites and unchanged drug.
