CONEXXENCE vs TRIPHASIL-21
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CONEXXENCE is a combination hormonal contraceptive that suppresses gonadotropin (FSH and LH) release via inhibition of hypothalamic GnRH, thereby preventing ovulation. The progestin component (desogestrel) also increases cervical mucus viscosity and alters endometrial receptivity.
Combination of ethinyl estradiol and levonorgestrel suppresses gonadotropin release, inhibiting ovulation; alters cervical mucus to impair sperm penetration and endometrial receptivity.
CONEXXENCE is not a recognized pharmaceutical agent. No standard dosing information available.
One tablet orally daily for 21 days, followed by 7 drug-free days. Each tablet contains levonorgestrel 0.05 mg and ethinyl estradiol 0.03 mg (days 1-6), levonorgestrel 0.075 mg and ethinyl estradiol 0.04 mg (days 7-11), and levonorgestrel 0.125 mg and ethinyl estradiol 0.03 mg (days 12-21).

Terminal elimination half-life: 12–18 hours; allows twice-daily dosing; prolonged in severe renal impairment (up to 40 hours).
Levonorgestrel: 10-45 hours (terminal, biphasic); ethinyl estradiol: 10-27 hours (terminal, triphasic). Clinical context: Steady state reached after 7-14 days with daily dosing.
Renal: 70% unchanged; fecal: 30% (including metabolites).
Renal: 30-50% (ethinyl estradiol and levonorgestrel metabolites as glucuronide and sulfate conjugates). Fecal: 30-50% (biliary excretion of unconjugated metabolites). Unchanged drug: negligible.
