Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and norethindrone suppresses gonadotropin-releasing hormone (GnRH) from the hypothalamus, reducing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion from the pituitary, thereby inhibiting ovulation. Additionally, induces changes in cervical mucus and endometrium to impede sperm penetration and implantation.
Zinc pyrithione is an antimicrobial agent that inhibits fungal growth by disrupting membrane transport and inhibiting mitochondrial function, leading to cell death.
One tablet orally once daily for 21 days, followed by 7 days of placebo tablets. Each active tablet contains 1 mg norethindrone acetate and 20 mcg ethinyl estradiol.
Intravenous infusion of 300 mg over 30 minutes every 4 weeks.

Ethinyl estradiol: 13-27 hours (terminal); norethindrone: 5-14 hours (terminal). Clinically, steady-state is achieved within 5-6 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 (primarily as metabolites; ~50-60% of dose), fecal (~30-40% of dose). Unchanged drug excretion is minimal.
Primarily hepatic metabolism with renal excretion of metabolites (50-60% as unchanged drug and conjugates); approximately 30-40% fecal elimination.
