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); inhibits serotonin reuptake at the presynaptic neuron, enhancing serotonergic neurotransmission.

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 half-life of 12-15 hours (range 10-18h) in adults; prolonged in renal impairment (up to 30h in severe cases).
Renal: 85% (12% unchanged, 73% as glucuronide conjugates); biliary/fecal: 3%
Primarily renal excretion of unchanged drug (60-80%); biliary/fecal elimination accounts for 15-20%.
