Verapamil is a prescription drug for the treatment of heart disease such as:

  • High blood pressure
  • Prevention and long-term treatment of angina pectoris attack
  • Slowing down of abnormally fast heartbeats like atrial flutter/ fibrillation and supraventricular tachycardia

High blood pressure or hypertension is a common condition but when left untreated it can causes damages to the heart, brain, blood vessels, kidney and other organs of the body. Damages to these organs can cause stroke, heart failure, heart attack, loss of vision, kidney failure and other problems.

Verapamil belongs to the group of drug known as calcium channel blockers or CCBs. It acts on the heart and the blood vessels. It works by slowing down the movement of calcium into the muscles of the coronary arteries as well as other arteries of the body. Verapamil blocks the calcium channels on the muscle cells.

Calcium is needed by the muscle cells for contraction. Since it triggers contraction of the muscle, Verapamil blocks it entry causing the muscle cells that surrounds the arteries to relax. This allows the arteries to become large so more blood can flow through them. The relaxation of the muscle cells thus relieves pain from contraction, lowers the blood pressure and reduces the pressure against which the heart must pump blood. As a result, the heart won’t have to work so hard in pumping blood and requires less oxygen-carrying blood. Verapamil has other numerous physiologic effects like:

  • Decreased cardiac contractility
  • Slowed atrioventricular node contraction
  • Vasodilation of both peripheral and coronary arteries and arterioles
  • Depressed sinus node activity

Aside from the mentioned effects, Verapamil can also:

  • Increase the heart’s dependence on carbohydrate rather than on fatty acids
  • Interferes with the energy metabolism of cardiac cells
  • Inhibits the production of insulin by the pancreas

Because of its effect on the blood vessels and heart, Verapamil has an array of other uses:

  • Migraine prophylaxis
  • Cluster headache prophylaxis
  • Malignant refractory hypertension
  • Raynaud’s phenomenon

    • Decrease kidney function
    • Decrease liver function
    • Heart failure
    • Slowed conduction of electrical messages between the chambers of the heart
    • Myasthenia gravis
    • Lambert-Eaton syndrome
    • An Advanced Duchenne muscular dystrophy
  • Do not use in people who:
    • Have failure of the heart to maintain enough circulation of blood
