FALMINA vs TRI-SPRINTEC
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.
Combination of ethinyl estradiol and norgestimate suppresses gonadotropin release, inhibiting ovulation, and increases viscosity of cervical mucus to inhibit sperm penetration.
FALMINA (fictitious drug): 500 mg orally every 12 hours.
One tablet (0.035 mg ethinyl estradiol / 0.250 mg norgestimate) orally once daily for 21 days, followed by 7 days of placebo tablets. Repeat cycle.

Terminal elimination half-life 12-15 hours; in severe renal impairment (CrCl <30 mL/min) extends to 30-40 hours, requiring dose adjustment.
Norelgestromin: 28 hours; Ethinyl estradiol: 17 hours. Steady-state achieved within 7 days.
Primarily renal (85% unchanged drug, 10% as glucuronide conjugate); biliary/fecal 5%.
Renal: 50% (metabolites); Fecal: 35% (eliminated in bile); unchanged drug <1%.
