Terminal elimination half-life of 20-30 hours; at steady state after 5-7 days, half-life reflects accumulation for once-daily dosing.
Ethinyl estradiol: 13-27 hours (mean ~17 hours); norethindrone: 5-14 hours (mean ~8 hours); terminal half-life supports once-daily dosing.
Primarily hepatic metabolism with renal excretion of metabolites (50-60% as unchanged drug and conjugates); approximately 30-40% fecal elimination.
Renal: 50-60% as metabolites; fecal: 30-40% as conjugates; biliary excretion significant.
