LEVLITE vs TAYTULLA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Levonorgestrel is a progestin that suppresses ovulation by inhibiting gonadotropin release (LH and FSH) and alters cervical mucus, endometrial thickness, and tubal motility.
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 (levonorgestrel 0.1 mg, ethinyl estradiol 0.02 mg) orally once daily for 21 days, followed by 7 placebo tablets.
One capsule orally once daily for 24 weeks.
