Isosorbide dinitrate is classified in the family of drugs known as nitrates. It is a vasodilator and as such it expands arteries and veins within the body and allows for more ease of blood flow. This expansion lowers the pressure in the arteries and allows the heart to do its pumping work with less strain. Isosorbide dinitrate is commonly given to relieve chest pain.
Isosorbide dinitrate is often administered as a tablet that can be taken with or without food. Sublingual tablets are designed to be dissolved underneath the tongue. Never chew, crush, or bite into tablets. Your physician may feel that another form of delivery would be easier or more
