Common questions about verapamil
What is the difference between Calan and verapamil?
Calan is the originator brand of verapamil, originally developed by Searle. The active ingredient is identical to generic verapamil; the name Calan simply refers to the branded version of the same medicine.
Is verapamil a beta blocker?
No, verapamil is a calcium channel blocker, not a beta blocker. Although it can slow the heart and lower blood pressure, it does so by a different mechanism, blocking calcium entry into heart and blood vessel cells.
