Information About Calan SR Drug

Calan SR (Verapamil)

Calan SR is a calcium channel blocker which works by relaxing the blood vessels and muscles of the heart to help blood flow. It is used to treat heart rhythm disorders, angina, and high blood pressure. Calan medication helps to lower the blood pressure thus reducing the risk of heart attacks, strokes, and kidney problems. It may also bring down your heart rate.

You can buy Calan SR from Canada Pharmacy at the best rate and have it delivered to your doorstep.


Calan medication should be taken once daily or as prescribed by your doctor. Do not crush or chew these tablets but swallow them as a whole. The dosage depends on your reaction to Calan SR treatment and the severity of your medical condition. Most people who experience high blood pressure do not feel sick and discontinue use after some time. For best results, Calan SR should be taken regularly even if you feel better. It might take a week for blood pressure patients to experience any improvement in their condition.

Calan SR should be administered with food with low initial doses of Calan SR 120mg every day for patients who have an increased reaction to verapamil for example children or the elderly. If a favorable response is not achieved with a lower dose, then it should be increased to Calan SR 240mg daily.


The active ingredient of Calan SR is Verapamil Hydrochloride.
