MARLISSA vs SIMPESSE
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.
Simpesse is a combination estrogen-progestin oral contraceptive that suppresses gonadotropin release, primarily inhibiting ovulation via negative feedback on the hypothalamic-pituitary-ovarian axis. Additionally, it alters cervical mucus viscosity and endometrial receptivity.
MARLISSA 20 mg orally once daily with or without food.
Oral: 10 mg once daily, taken at least 1 hour before a meal.

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.
Terminal elimination half-life is 24 hours (range 20-28 hours), supporting once-daily dosing.
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 excretion of unchanged drug accounts for approximately 60-70% of elimination; hepatic metabolism produces inactive metabolites that are excreted renally (20-30%) and fecally (<10%).
