Used For

How it works

Verapamil is a calcium-channel blocker.

  • Relaxes blood vessels, reducing vascular resistance → lowers blood pressure.

  • Decreases workload on the heart.

  • Increases oxygen and blood supply to the myocardium.

  • Slows electrical conduction in the heart → helps regulate heart rhythm.
