MARLISSA vs ORTHO-NOVUM 7/14-21
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Combination estrogen-progestin contraceptive: suppresses gonadotropin release, inhibits ovulation, thickens cervical mucus, alters endometrial receptivity.
MARLISSA 20 mg orally once daily with or without food.
One tablet containing 0.5 mg norethindrone/0.035 mg ethinyl estradiol (white tablets) on days 1-14, then one tablet containing 1 mg norethindrone/0.035 mg ethinyl estradiol (peach tablets) on days 15-21, then no tablets for 7 days; repeated cycles.

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: 10-12 hours (terminal), ethinyl estradiol: 13-27 hours (terminal); clinical context: steady state achieved within 5-7 days
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.
Renal: ~40% as glucuronide and sulfate conjugates; Fecal: ~20%; Biliary: minor
