Prescription required
Isosorbide Mononitrate is used to prevent chest pain (angina) in patients with coronary artery disease. It belongs to a class of drugs called nitrates, which work by relaxing and widening blood vessels, allowing more blood and oxygen to reach the heart. Imdur is not intended to relieve acute chest pain once it occurs. Instead, it helps reduce the frequency and severity of angina attacks.
