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.
MARLISSA is a combination of ethinyl estradiol, a synthetic estrogen, and drospirenone, a progestin with antimineralocorticoid and antiandrogenic activity. It suppresses gonadotropins, inhibiting ovulation, and alters cervical mucus and endometrial lining.
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.
MARLISSA 20 mg orally once daily with or without food.

Norethindrone: 7-8 hours; Ethinyl estradiol: 13-16 hours. Steady-state achieved within 5 days.
Terminal elimination half-life is 12-18 hours (mean 15 hours) in healthy adults. In moderate-to-severe hepatic impairment, half-life may be prolonged to 30-40 hours; no significant change in renal impairment.
Norethindrone: ~40% renal, ~60% fecal; Ethinyl estradiol: ~40% renal, ~60% fecal as glucuronide and sulfate conjugates.
Primarily renal (75-80% as unchanged drug) via glomerular filtration and tubular secretion; 10-15% fecal via biliary excretion; 5-10% metabolized with metabolites also renally eliminated.
