FALMINA vs OVRAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the synaptic cleft, leading to increased serotonin levels.
OVRAL is a combination oral contraceptive containing ethinyl estradiol and norgestrel. It inhibits ovulation by suppressing gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus, reducing follicle-stimulating hormone (FSH) and luteinizing hormone (LH) release from the pituitary. Additionally, it increases cervical mucus viscosity and alters endometrial receptivity, impeding sperm penetration and implantation.
FALMINA (fictitious drug): 500 mg orally every 12 hours.
One tablet (norgestrel 0.3 mg with ethinyl estradiol 0.03 mg) orally once daily for 21 days followed by 7 days of placebo.

Terminal elimination half-life 12-15 hours; in severe renal impairment (CrCl <30 mL/min) extends to 30-40 hours, requiring dose adjustment.
Norgestrel: 24–32 hours; Ethinyl estradiol: 12–18 hours; steady-state achieved after 5–7 days
Primarily renal (85% unchanged drug, 10% as glucuronide conjugate); biliary/fecal 5%.
Renal (60% as metabolites, ~40% unchanged); biliary/fecal (40%)
