About this product
Overview
Ismo 20 Tablet contains the active ingredient isosorbide mononitrate, which belongs to the class of medications known as organic nitrates. Isosorbide mononitrate is a vasodilator that works by relaxing and widening the blood vessels, primarily in the veins, reducing the workload on the heart and improving blood flow to the heart muscle.
