CONEXXENCE vs LEVLITE
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.
Levonorgestrel is a progestin that suppresses ovulation by inhibiting gonadotropin release (LH and FSH) and alters cervical mucus, endometrial thickness, and tubal motility.
CONEXXENCE is not a recognized pharmaceutical agent. No standard dosing information available.
One tablet (levonorgestrel 0.1 mg, ethinyl estradiol 0.02 mg) orally once daily for 21 days, followed by 7 placebo tablets.
