How does isosorbide dinitrate work? The methemoglobinemia associated with isosorbide toxicity is manageable by supportive care and cessation of isosorbide. The predominant venodilation results in decreased venous return to the heart by reducing the left ventricular end-diastolic volume, left ventricular end-diastolic pressure(preload), and the ventricular wall tension,therebyindirectly facilitating subendocardial blood flow. Isosorbide belongs to the nitrate group of medications that acts by releasing nitric oxide (N0), thereby causing vasodilation. Caution if used in nursing women.
