SIMPESSE vs YASMIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Combination of ethinyl estradiol and drospirenone suppresses gonadotropins, inhibiting ovulation. Drospirenone has antimineralocorticoid activity, reducing water retention, and antiandrogenic activity.
Oral: 10 mg once daily, taken at least 1 hour before a meal.
One tablet (ethinyl estradiol 0.03 mg / drospirenone 3 mg) orally once daily for 21 days, followed by 7 days of placebo.

Terminal elimination half-life is 24 hours (range 20-28 hours), supporting once-daily dosing.
Terminal elimination half-life is approximately 30 hours for drospirenone; steady-state concentration is achieved after 10 days of daily dosing.
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%).
Approximately 40% renal and 60% fecal after oral administration; metabolites are excreted as glucuronide and sulfate conjugates.
