Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Minoxidil is a potassium channel opener that causes direct vasodilation of peripheral arteries. It reduces peripheral vascular resistance and blood pressure by hyperpolarizing vascular smooth muscle cells via activation of ATP-sensitive potassium channels.
Selective serotonin reuptake inhibitor (SSRI); increases serotonin levels in the synaptic cleft by blocking reuptake via SERT inhibition.
10 mg orally twice daily, titrated to 40 mg twice daily for hypertension; for heart failure, start at 2.5-5 mg orally twice daily, max 20 mg twice daily.
1.5 mg/kg IV every 12 hours; maximum single dose 120 mg.

Terminal elimination half-life: 4.2 hours (range 3.5–5.5); clinically, half-life extends to 14–23 hours after chronic dosing due to drug accumulation.
Terminal elimination half-life 12 hours; prolonged to 24-36 hours in severe renal impairment (CrCl <30 mL/min)
Renal: 85% (12% unchanged, 73% as glucuronide conjugates); biliary/fecal: 3%
Renal excretion unchanged 70%, biliary/fecal 25%, metabolic clearance 5%
