Indications
Isoptin SR is an antiarrhythmic medication used alone or with other medicines to treat heart rhythm problems as well as severe chest pain (angina) and high blood pressure (hypertension).
Verapamil is a calcium channel blocker that inhibits calcium from moving into your heart and blood cells. This action causes your blood vessels to relax which increases blood flow and the amount of oxygen that is available to your heart. Thanks to these properties, Isoptin SR can help treat heart rhythm issues, angina, and hypertension by maintaining proper heart health and rhythm.
