CONEXXENCE vs QUARTETTE
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 oral contraceptive containing drospirenone, ethinyl estradiol, levomefolate calcium, and metformin. Drospirenone is a progestin with antimineralocorticoid and antiandrogenic activity. Ethinyl estradiol is an estrogen. Levomefolate calcium is a folate supplement. Metformin is a biguanide that decreases hepatic glucose production and improves insulin sensitivity.
CONEXXENCE is not a recognized pharmaceutical agent. No standard dosing information available.
3 mg orally once daily for 21 days followed by 7 days of placebo.

Terminal elimination half-life: 12–18 hours; allows twice-daily dosing; prolonged in severe renal impairment (up to 40 hours).
Terminal elimination half-life is 12-14 hours; clinically this supports once-daily dosing with steady state achieved within 2-3 days.
Renal: 70% unchanged; fecal: 30% (including metabolites).
Renal excretion accounts for 55% (primarily as unchanged drug), biliary/fecal excretion 35%, and the remainder undergoes metabolic clearance.
