Overview of Isoptin (verapamil)

Isoptin, also known as verapamil, is a medication that belongs to the class of calcium channel blockers. It is primarily used to treat high blood pressure, angina (chest pain), and certain heart rhythm disorders such as atrial fibrillation or atrial flutter. Verapamil works by relaxing blood vessels, making it easier for the heart to pump blood and reducing the workload on the heart.

Verapamil is available in multiple formulations, including immediate-release tablets, extended-release tablets, and intravenous injection. The appropriate formulation is typically determined by the individual’s condition and response to treatment.

How Does Isoptin (Verapamil) Work?

Isoptin (verapamil) works by blocking the flow of calcium into the muscle cells of the heart and blood vessels. Calcium is necessary for muscle contraction, including the contraction of the heart muscle. By blocking calcium channels, verapamil helps relax and widen blood vessels, reducing blood pressure and improving blood flow to the heart.

Uses of Isoptin (Verapamil)

1. Treatment of Hypertension:

Verapamil is commonly prescribed to manage high blood pressure. It helps lower blood pressure by relaxing and widening blood vessels, allowing blood to flow more easily. This can help prevent complications associated with high blood pressure, such as stroke, heart attack, and kidney problems.
