Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination hormonal contraceptive: ethinyl estradiol suppresses gonadotropin release, inhibiting ovulation; norethindrone induces endometrial changes, increasing cervical mucus viscosity.
Combination oral contraceptive containing ethinyl estradiol (estrogen) and norethindrone (progestin). Inhibits ovulation by suppressing gonadotropin release; increases viscosity of cervical mucus, inhibiting sperm penetration; alters endometrial lining, reducing implantation likelihood.
One tablet orally once daily for 21 consecutive days, followed by 7 days of placebo tablets.
