Uses of Imdur

• Isosorbide mononitrate is in a class of drugs called nitrates. Isosorbide mononitrate dilates (widens or relaxes) blood vessels (arteries and veins). When blood vessels are dilated, it is easier for the heart to pump. Also, more blood, which is rich in oxygen, can flow to the heart.
• Isosorbide is used to prevent angina attacks (chest pain).
