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.
Zinc pyrithione is an antimicrobial agent that inhibits fungal growth by disrupting membrane transport and inhibiting mitochondrial function, leading to cell death.
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.
Intravenous infusion of 300 mg over 30 minutes every 4 weeks.

Norgestrel: ~45 hours (terminal). Ethinyl estradiol: ~13 hours (terminal). Steady-state achieved within 5-7 days.
Terminal elimination half-life of 20-30 hours; at steady state after 5-7 days, half-life reflects accumulation for once-daily dosing.
Renal 50-60% as metabolites, fecal 40-50% via biliary elimination. Ethinyl estradiol undergoes enterohepatic recirculation.
Primarily hepatic metabolism with renal excretion of metabolites (50-60% as unchanged drug and conjugates); approximately 30-40% fecal elimination.
