CONEXXENCE vs OVULEN-28
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 estrogen-progestin oral contraceptive that inhibits ovulation primarily by suppressing gonadotropin-releasing hormone (GnRH) from the hypothalamus, reducing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) secretion, and altering cervical mucus and endometrial lining.
CONEXXENCE is not a recognized pharmaceutical agent. No standard dosing information available.
One tablet (ethinyl estradiol 0.05 mg / ethynodiol diacetate 1 mg) orally once daily for 21 days followed by 7 days placebo; continuous cycle.
