Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination estrogen-progestin contraceptive that suppresses gonadotropin release (FSH and LH) from the pituitary, inhibiting ovulation. Additionally, increases viscosity of cervical mucus and alters endometrial receptivity.
Norepinephrine and dopamine reuptake inhibitor; also weakly inhibits serotonin reuptake. Enhances synaptic concentrations of norepinephrine and dopamine, particularly in prefrontal cortex.
One tablet orally once daily for 21 consecutive days, followed by 7 days of placebo tablets.
100 mg orally once daily with food.

Ethinyl estradiol: terminal half-life ~17-24 hours; norethindrone: terminal half-life ~5-14 hours (mean 11 hours). The clinical significance is that steady-state is reached within 5-7 days.
Terminal elimination half-life is approximately 12-15 hours in healthy adults; prolonged in renal impairment (up to 30 hours in severe impairment).
Ethinyl estradiol is primarily excreted renally (40-45%) and via bile/feces (45-55%). Norethindrone is excreted 50-60% renally and 30-40% fecally.
Primarily renal excretion as unchanged drug (approximately 70%) with the remainder as inactive metabolites; less than 10% excreted in feces.
