Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination hormonal contraceptive: ethinyl estradiol suppresses gonadotropin release, inhibiting ovulation; norethindrone induces endometrial changes, increasing cervical mucus viscosity.
Bile acid sequestrant; binds bile acids in the intestine, forming an insoluble complex that is excreted in feces, thereby reducing enterohepatic circulation of bile acids and promoting conversion of cholesterol to bile acids in the liver, leading to decreased serum LDL cholesterol.
One tablet orally once daily for 21 consecutive days, followed by 7 days of placebo tablets.
100 mg orally once daily, with or without food.

Terminal elimination half-life: 15-18 hours for ethinyl estradiol; clinical context: supports once-daily dosing
Terminal elimination half-life is 12-16 hours in adults with normal renal function; may extend to >40 hours in severe renal impairment (CrCl <30 mL/min).
Renal (approximately 60% as metabolites, 10-15% as unchanged drug); fecal (about 20-30%)
Primarily renal, with 70-80% of the dose excreted unchanged in urine; 10-20% via feces through biliary elimination.
