Nitroglycerin works by causing your veins to expand or dilate, known as venodilation. It also works on dilating the coronary arteries, contributing to the relief of angina.
If you have coronary artery disease, you may benefit from using nitroglycerin. This prescription drug is designed for many uses, but can help prevent or treat angina (chest pain). It works by relaxing the arteries and the veins, which helps improve blood flow to the heart.
