ShareIsosorbide Dinitrate is a nitrate that prevents chest pain or angina attacks.Isosorbide Dinitrate belongs to the category of drugs antianginal agents. It acts by dilating the blood vessels, therefore, making it easier for your blood to flow and also facilitates proper heart pumping. Isosorbide dinitrate is a drug used in the treatment and prevention of angina, or chest pain. It’s worth noting that only the sublingual formulation is appropriate to treat an angina attack. Isosorbide dinitrate may also be used for purposes not listed in this guide, at the discretion of the prescriber. Isosorbide dinitrate is used because it belongs to the nitrate class of medicines. As a nitrate, isosorbide dinitrate expands blood vessels – meaning blood pressure is reduced and more blood is able to flow around the body. As blood carries oxygen on its back, this is particularly useful in cases of angina where a lack of oxygen is what precipitates the patient’s pain. Common side effects associated with isosorbide dinitrate include headache and flushing. Some patients may also experience faintness, pounding heartbeats, and worsening angina.
