Isoptin SR is a medication used for the treatment of high blood pressure. Blood pressure is the force of the blood against the walls of your blood vessels and when that force is high, it causes your heart to have to work harder which can cause damage. If hypertension goes treated for too long, a person risks health conditions such as heart attack, stroke, and kidney problems. Additionally, this medication may be used to prevent chest pain (angina), which may also help improve your ability to exercise while decreasing the frequency of angina attacks.
Isoptin SR (verapamil) is effective in treating hypertension and preventing angina because it is able to relax the blood vessels so blood can flow more easily while also controlling your heart rate.
