Two medicines, side by side
Candesartan vs amlodipine
Candesartan and amlodipine are both labeled for high blood pressure. Drugs@FDA records approvals of candesartan since 1998 and of amlodipine since 1992. Pharmacies paid $0.478 per candesartan cilexetil 16 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, candesartan is an angiotensin 2 receptor blocker and amlodipine a calcium channel blocker.
Check it at the source: the candesartan FDA label on DailyMed (effective January 15, 2026); the amlodipine FDA label on DailyMed (effective February 15, 2023).
