Overview

Calan belongs to a class of medicines called calcium channel blockers.

Because of their safety and effectiveness, these drugs have helped revolutionize the treatment of high blood pressure.

Other uses of calcium channel blockers include treatment of irregular heart rhythms and angina.

There is even some preliminary research that suggests some of these compounds may be able to prevent migraine headaches, ease nighttime leg cramps, asthma and Raynaud's disease, and perhaps reduce atherosclerosis.

Despite these future possibilities, Calan SR has been approved only for the treatment of hypertension.
