Calan and Isoptin are brand names for which medication?

• A. Diltiazem
• B. Propranolol
• C. Verapamil
• D. Cardizem

Answer: (C)

Calan and Isoptin are names used for verapamil, a calcium channel blocker. Verapamil works by blocking L-type calcium channels in the heart and blood vessels, which slows AV nodal conduction and relaxes vascular smooth muscle. This leads to a lower heart rate, reduced force of contraction, and vasodilation—helpful in treating hypertension, angina, and certain arrhythmias. Cardizem is a brand for diltiazem, another calcium channel blocker, while propranolol is a beta-blocker, not verapamil. So the medication associated with Calan and Isoptin is verapamil.
