What Is Isradipine CR Used For? -- An Overview

Isradipine CR (Dynacirc CR^®) is a prescription medication used to treat high blood pressure (hypertension).

 

A blood pressure reading consists of two numbers, for example: 120/80. The top number is known as the systolic blood pressure, and the bottom number is the diastolic blood pressure. High blood pressure is defined as an average blood pressure higher than 140/90 with multiple blood pressure readings.

 

In clinical studies, isradipine CR was shown to significantly lower both systolic and diastolic blood pressure. By lowering blood pressure, the drug can decrease the risk of developing health problems (such as a stroke, heart disease, or congestive heart failure) that occur with long-term high blood pressure (see Effects of High Blood Pressure). Isradipine CR is not a cure for high blood pressure, however.

 

How Isradipine CR Works

Isradipine CR is part of a class of drugs called calcium channel blockers. It helps slow down the rate at which calcium moves into your heart and blood vessel walls. This, in turn, helps to relax the vessels, which allows better blood flow and helps to lower blood pressure. It also makes it easier for the heart to pump blood.

 

There are two basic types of calcium channel blockers: dihydropyridine and non-dihydropyridine. The most important difference between the two is that non-dihydropyridine calcium channel blockers can slow down the heart rate, while dihydropyridine calcium channel blockers do not. Isradipine CR is a dihydropyridine calcium channel blocker, which means that it does not usually decrease the heart rate.
