Nitro Dur is used for the treatment of angina, which is chest pain. Angina occurs when the coronary arteries become constricted and are not able to carry sufficient oxygen to the heart muscle. Nitro Dur relaxes the walls of the arteries and veins, allowing them to dilate so that oxygen can flow through them.
