Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination hormonal contraceptive. Norethindrone acetate suppresses gonadotropin release (FSH and LH) via progestogenic activity, inhibiting ovulation. Ethinyl estradiol provides negative feedback on hypothalamic-pituitary axis, further suppressing gonadotropins and stabilizing endometrium.
Combination of ethinyl estradiol and drospirenone; primarily suppresses gonadotropins (FSH, LH) via negative feedback, preventing ovulation. Drospirenone has anti-mineralocorticoid and anti-androgenic activity.
One tablet (0.10 mg ethinyl estradiol / 1.0 mg norethindrone acetate) orally once daily for 24 days, followed by 4 days of ferrous fumarate 75 mg tablets (placebo). Administer at the same time each day without interruption.
One tablet orally once daily for 24 weeks, followed by placebo tablets for 4 weeks; each tablet contains 0.15 mg levonorgestrel and 0.03 mg ethinyl estradiol for 21 days, then 0.01 mg ethinyl estradiol for 3 days, then 2 tablets of 75 mg ferrous fumarate for 5 days.

Norethindrone: 7-8 hours; Ethinyl estradiol: 13-16 hours. Steady-state achieved within 5 days.
Drospirenone: 25-33 hours; Ethinyl estradiol: 13-24 hours; steady-state achieved after 10 days.
Norethindrone: ~40% renal, ~60% fecal; Ethinyl estradiol: ~40% renal, ~60% fecal as glucuronide and sulfate conjugates.
Renal: 30-40% as drospirenone metabolites, 20-30% as ethinyl estradiol metabolites; fecal: 40-50% as drospirenone metabolites, 30-40% as ethinyl estradiol metabolites; biliary: minimal.
