Two medicines, side by side
Minoxidil vs amlodipine
Minoxidil and amlodipine are both labeled for high blood pressure. Drugs@FDA records approvals of minoxidil since 1979 and of amlodipine since 1992. Pharmacies paid $0.156 per minoxidil 10 mg tablet and $0.0102 per amlodipine besylate 5 mg tablet (NADAC, October 7, 2026); the strengths differ, so the two prices are not like for like. In FDA's classes, minoxidil is an arteriolar vasodilator and amlodipine a calcium channel blocker.
