OVRAL vs TAYTULLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
OVRAL is a combination oral contraceptive containing ethinyl estradiol and norgestrel. It inhibits ovulation by suppressing gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus, reducing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) release from the pituitary. Additionally, it increases cervical mucus viscosity and alters endometrial receptivity, impeding sperm penetration and implantation.
Combination of drospirenone, a spironolactone analog with antimineralocorticoid and antiandrogenic activity, and ethinyl estradiol, an estrogen. Suppresses gonadotropins, primarily luteinizing hormone, inhibiting ovulation. Increases cervical mucus viscosity and alters endometrial receptivity.
One tablet (norgestrel 0.3 mg with ethinyl estradiol 0.03 mg) orally once daily for 21 days followed by 7 days of placebo.
One capsule orally once daily for 24 weeks.
