Isordil Titradose Generic descriptionsThe chest pain of coronary heart disease angina usually occurs when the heart requires more blood and oxygen than its coronary vessels can deliver. This demand for oxygen is related in part to blood pressure. The demand for oxygen can be reduced in one of two ways. First dilating the veins and pooling the blood lowers the blood pressure. Second dilating the arteries reduces the pressure that the heart has to pump against. Isosorbide dinitrate reduces angina by dilating both the veins and the arteries. Isosorbide dinitrate is in the class of drugs called anti-anginal medications.
