TAYTULLA vs TRI-LO-ESTARYLLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of drospirenone, a spironolactone analog with antimineralocorticoid and antiandrogenic activity, and ethinyl estradiol, an estrogen. Suppresses gonadotropins, primarily luteinizing hormone, inhibiting ovulation. Increases cervical mucus viscosity and alters endometrial receptivity.
Combination oral contraceptive containing ethinyl estradiol and norgestimate. Suppresses gonadotropin secretion, primarily FSH and LH, inhibiting ovulation; increases cervical mucus viscosity, impeding sperm penetration; alters endometrial lining, reducing implantation likelihood.
One capsule orally once daily for 24 weeks.
One tablet (20 mcg ethinyl estradiol/0.1 mg levonorgestrel) orally once daily for 21 days, followed by 7 days of placebo.

Terminal elimination half-life: 30 hours. Provides once-daily dosing with steady-state achieved after 7 days.
Ethinyl estradiol: 19-24 hours (terminal); Norgestimate: active metabolite norelgestromin 28-38 hours; allows once-daily dosing.
Renal: ~60% as unchanged drug; Fecal: ~40% as metabolites and unchanged drug.
Renal: ~40% as metabolites; Fecal: ~30% as metabolites (including ethinyl estradiol conjugates); Biliary: ~20% (enterohepatic recirculation).
