Isosorbide Mononitrate```

Cardiovascular diseases remain one of the leading causes of morbidity and mortality in India. Among these, angina pectoris, a condition characterized by chest pain due to reduced blood flow to the heart muscle, significantly affects quality of life and daily functioning. Effective long-term management of angina is essential to prevent complications such as heart attacks and heart failure.

STERIS'S ISMN 20 is a trusted formulation containing Isosorbide Mononitrate, a well-established anti-anginal medication widely prescribed in cardiology practice. Isosorbide Mononitrate belongs to the class of medicines known as organic nitrates, which work by relaxing and widening blood vessels, thereby improving blood flow to the heart and reducing cardiac workload.

By decreasing the heart’s oxygen demand and enhancing coronary circulation, STERIS'S ISMN 20 helps prevent angina attacks, improves exercise tolerance, and supports overall heart health. It is commonly used in patients with chronic stable angina and is also beneficial in certain cases of heart failure and ischemic heart disease.
