CONEXXENCE vs DASETTA 1/35
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 an estrogen (ethinyl estradiol) and a progestin (norethindrone). Suppresses gonadotropin-releasing hormone (GnRH) from the hypothalamus, reducing luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion from the pituitary, thereby inhibiting ovulation. Additionally, induces changes in cervical mucus (impenetrability to sperm) and endometrium (reduced likelihood of implantation).
CONEXXENCE is not a recognized pharmaceutical agent. No standard dosing information available.
One tablet orally once daily, each containing 1 mg norethindrone acetate and 35 mcg ethinyl estradiol.
