What is Isosorbide ?

Isosorbide is a medication commonly used in the management of chronic heart conditions, specifically for treating and preventing angina pectoris. It works by relaxing and widening blood vessels, which allows blood to flow more easily, thereby reducing the heart's workload and oxygen demand. This medication is typically administered in tablet form and must be prescribed by a healthcare provider.
