CYCLESSA vs TAYTULLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of estrogen (ethinyl estradiol) and progestin (desogestrel) inhibits ovulation by suppressing gonadotropin release, increases viscosity of cervical mucus to impede sperm penetration, and alters endometrial receptivity.
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.
One tablet (0.15 mg desogestrel/0.02 mg ethinyl estradiol) orally once daily for 21 days, followed by 7 days of placebo.
One capsule orally once daily for 24 weeks.

Desogestrel: 38±13 hours (terminal); ethinyl estradiol: 14±3 hours (terminal). Steady-state reached after 7-10 days.
Terminal elimination half-life: 30 hours. Provides once-daily dosing with steady-state achieved after 7 days.
Urine (50-60% as metabolites, <10% unchanged); feces (30-40% as metabolites); enterohepatic circulation.
