OVULEN-28 vs TAYTULLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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 (ethinyl estradiol 0.05 mg / ethynodiol diacetate 1 mg) orally once daily for 21 days followed by 7 days placebo; continuous cycle.
One capsule orally once daily for 24 weeks.
