What is Isoptin used for? 

Isoptin (generic name: verapamil hydrochloride) is an oral medication indicated to manage essential hypertension. This is the type of hypertension with no identifiable cause. By lowering high blood pressure, kidney problems, strokes, and heart attacks can be prevented. In addition to treating angina pectoris (chest pain) and controlling heart rate, this drug is also used to treat irregular heart rhythms, such as atrial fibrillation.

This is available in Isoptin 120 mg and 80 mg tablet forms. 

How does Isoptin work? 

This calcium channel blocker works by decreasing the systemic vascular resistance but often without an orthostatic decrease in blood pressure (BP) or reflex tachycardia. It also works by dilating the main coronary arteries, as well as the coronary arterioles. It also inhibits coronary artery spasm. This results in increased myocardial oxygen delivery. This drug also has the capacity to regularly reduce cardiac afterload or the total systemic resistance against the heart.
