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 arterioles. It increases blood flow to hair follicles and prolongs the anagen (growth) phase of hair follicles.
Minoxidil is a direct-acting peripheral vasodilator that opens ATP-sensitive potassium channels in vascular smooth muscle cells, leading to hyperpolarization and relaxation. In hair follicles, it promotes hair growth by increasing blood flow, stimulating prostaglandin synthesis, and prolonging the anagen phase.
Topical: 1 mL of 5% solution (50 mg) applied to the scalp twice daily. Maximum daily dose: 2 mL (100 mg).
Oral: 2.5-5 mg once daily; may increase to 10 mg once daily if needed. Topical: 5% solution, 1 mL applied to dry scalp twice daily; 5% foam, half a capful applied twice daily; 2% solution, 1 mL applied twice daily.

Terminal elimination half-life is approximately 4.2 hours in patients with normal renal function. However, the pharmacodynamic half-life (duration of antihypertensive effect) is about 24 hours, allowing once-daily dosing.
Terminal half-life: 3.5-4.5 hours. Clinical context: Short half-life necessitates twice-daily dosing for hypertension; for topical use, systemic absorption is minimal so half-life less relevant.
Primarily renal (approximately 95% as parent drug and metabolites). Biliary/fecal excretion is minimal (less than 5%).
Renal: 85-90% (primarily unchanged drug and metabolites). Biliary/fecal: <5%.
