Congestive heart failure: Oral: Initial: 10 mg 3 times/day. Growing cells of Tetrahymena thermophila (T. t.) metabolized, after 72 h, 80% of isosorbide dinitrate (ISDN) to isosorbide 5-mononitrate (5-ISMN) and isosorbide 2-mononitrate (2-ISMN) in a ratio 5-ISMN/2-ISMN=2.6 as evaluated by HPLC. 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. To initiate a feeding tube to oral interchange the patient must have passed a swallow study as documented in the medical record or approval to use the oral route is Relieves chest pain.

The organic nitrates are vasodilators, active on both arteries and veins.Each Dilatrate®-SR sustained release capsule contains 40 mg of isosorbide dinitrate, in a microdialysis delivery system that causes the active drug to be released over an extended period. In the Veterans Heart Failure Trial II, 35 the reduction in all-cause mortality rates (18% vs. 25%) with enalapril compared with hydralazine-isosorbide dinitrate was attributed to a reduction in the incidence of sudden death (37% vs. 46% of the total mortality) in the enalapril group. (dinitrate conventional tablets) two to three times daily. We compared the effect of isosorbide mononitrate or placeb. Isosorbide mononitrate has one nirate group and isosorbide dinatrate has 2 nitro groups. In contrast to all other organic nitrates, such as nitroglycerin (GTN), isosorbide-5-mononitrate (ISMN), and isosorbide dinitrate, PETN is an organic nitrate that is devoid of adverse effects, such as the induction of nitrate tolerance, vascular oxidative stress, and endothelial dysfunction (12,13). ISDN has a short half-life and is primarily effective clinically by metabolism to the active metabolite isosorbide-5-mononitrate, which has an average half-life of 5 hours.
