Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Combination of ethinyl estradiol and norethindrone suppresses gonadotropin release, inhibiting ovulation and altering cervical mucus and endometrial receptivity.
Levonorgestrel is a progestin that inhibits ovulation and alters cervical mucus, reducing sperm penetration. Ethinyl estradiol suppresses gonadotropin release, preventing follicular development.
