ARANELLE vs SIMPESSE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and norethindrone suppresses gonadotropin release, inhibiting ovulation and altering cervical mucus and endometrial receptivity.
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.
One tablet (norethindrone 1 mg and ethinyl estradiol 20 mcg) orally once daily for 21 days, followed by 7 days of placebo.
Oral: 10 mg once daily, taken at least 1 hour before a meal.

Terminal half-life 12-14 hours; steady-state achieved within 2-3 days; clinical context supports once-daily dosing
Terminal elimination half-life is 24 hours (range 20-28 hours), supporting once-daily dosing.
Renal 50-60% as metabolites (sulfate and glucuronide conjugates), fecal 30-40%, biliary 10%
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%).
