About
Isosorbide mononitrate is a long-acting nitrate primarily used for the prevention of angina pectoris, which is chest pain resulting from coronary artery disease. Its therapeutic action involves relaxing and widening blood vessels throughout the body, with a particular emphasis on veins. This vasodilation reduces the amount of blood returning to the heart, a physiological effect known as decreased preload. By lessening the heart's workload and its demand for oxygen, isosorbide mononitrate effectively prevents anginal attacks. Furthermore, it directly dilates coronary arteries, which improves blood flow and oxygen supply to the heart muscle itself. It is crucial to note that this medication is intended for sustained prophylactic treatment and not for the immediate relief of an acute angina episode.
