MIRCETTE vs YAELA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and desogestrel; estrogen and progestin inhibit gonadotropin release, suppressing ovulation and altering cervical mucus and endometrial receptivity.
Yaela is a combination of ethinyl estradiol and drospirenone. Ethinyl estradiol is an estrogen that suppresses gonadotropin release, inhibiting ovulation. Drospirenone is a progestin with antimineralocorticoid and antiandrogenic activity, contributing to contraceptive efficacy and reducing fluid retention.
One tablet daily for 21 days, followed by 7 placebo tablets. Each active tablet contains 0.015 mg ethinyl estradiol and 2 mg chlormadinone acetate. Route: oral.
The standard adult dose of Yaela (ethinyl estradiol/levonorgestrel) for oral contraception is 1 tablet (containing 0.03 mg ethinyl estradiol and 0.15 mg levonorgestrel) taken orally once daily at the same time each day for 21 days, followed by 7 days of placebo tablets.

Desogestrel active metabolite etonogestrel: 21-24 hours; ethinyl estradiol: 12-14 hours
Terminal elimination half-life is 12 ± 3 hours (range 8-16 hours) in patients with normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min).
Urine (50-60% as metabolites, <10% unchanged), feces (30-40% as metabolites)
Renal excretion of unchanged drug accounts for approximately 70% of the administered dose; biliary/fecal excretion accounts for 30%.
