At therapeutic levels, it predominately dilates the venous capacitance vessels but also the coronary arteries and the arterioles. Prolonged use of oral nitrates has been associated with the development of tolerance to the hemodynamic and antianginal effects and possibly with cross-tolerance to sublingual nitrates. isosorbide dinitrate (ISDN) isosorbide mononitrate (isosorbide-5-mononitrate; ISMN) .

The approximate onset and duration of action of various dosage forms of isosorbide dinitrate (ISDN) and isosorbide mononitrate (ISMN) are as follows: Onset and duration of action following intrabuccal administration are probably similar to those after sublingual administration of isosorbide dinitrate. Severe hypotension, particularly in upright position, can occur even with low doses. [17] Isosorbide does not need dose adjustment in patients with renal and hepatic dysfunction. 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. You can report any suspected side effect using the Yellow Card safety scheme. As the active metabolite of isosorbide dinitrate, ISMN does not require first-pass metabolism for activation and its longer half-life allows for twice-daily dosing. Isosorbide mononitrate: Metabolized principally in the liver, but unlike isosorbide dinitrate, does not undergo first-pass metabolism; metabolites appear to be pharmacologically inactive. The elimination half-life of isosorbide dinitrate is 1 hour, while the elimination half-life of isosorbide mononitrate is 5 to 6 hours. Miano C, Garcia-Tsao G.
