Used primarily in the treatment and prevention of angina pectoris, a condition characterized by chest pain due to reduced blood flow to the heart. It works by dilating blood vessels, which reduces the workload on the heart and improves oxygen supply to the cardiac muscle. The compound acts as a long-acting nitrate, providing sustained relief and helping to prevent the occurrence of angina attacks, especially during physical exertion or stress. It is commonly administered orally in tablet form and is favored for its predictable absorption and once- or twice-daily dosing regimen. Unlike some other nitrates, it produces fewer side effects such as headaches when dosed appropriately, and it does not require dose titration in most patients. Its stable pharmacokinetic profile makes it suitable for chronic management of coronary artery disease.
