Verapamil

Verapamil works by blocking calcium channels in the heart and blood vessels. This relaxes and widens the blood vessels, allowing for improved blood flow and reducing the workload on the heart. By regulating calcium levels, it also helps to control abnormal heart rhythms.

In addition to its cardiovascular uses, verapamil may sometimes be prescribed off-label for certain conditions such as migraines or cluster headaches.
