Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination hormonal contraceptive. Norethindrone acetate suppresses gonadotropin release (FSH and LH) via progestogenic activity, inhibiting ovulation. Ethinyl estradiol provides negative feedback on hypothalamic-pituitary axis, further suppressing gonadotropins and stabilizing endometrium.
Combination hormonal contraceptive: ethinyl estradiol suppresses LH and FSH, primarily inhibiting ovulation; drospirenone is a progestin with anti-mineralocorticoid and anti-androgenic activity, increasing cervical mucus viscosity and altering endometrial morphology.
One tablet (0.10 mg ethinyl estradiol / 1.0 mg norethindrone acetate) orally once daily for 24 days, followed by 4 days of ferrous fumarate 75 mg tablets (placebo). Administer at the same time each day without interruption.
One tablet orally once daily for 24 days followed by 4 placebo tablets. Each tablet contains 75 mcg desogestrel and 0.02 mg ethinyl estradiol.
