PRESCRIPTION DRUG
Isosorbide dinitrate tablets are indicated for the prevention of angina pectoris due to coronary artery disease. The onset of action of immediate-release oral isosorbide dinitrate is not sufficiently rapid for this product to be useful in aborting an acute anginal episode. Isosorbide dinitrate tablets are contraindicated in patients who are allergic to isosorbide dinitrate or any of its ingredients. Do not use isosorbide dinitrate tablets in patients who are taking certain drugs for erectile dysfunction (phosphodiesterase inhibitors), such as sildenafil, tadalafil, or vardenafil. Concomitant use can cause severe hypotension, syncope, or myocardial ischemia. Do not use isosorbide dinitrate tablets in patients who are taking the soluble guanylate cyclase stimulator riociguat. Concomitant use can cause hypotension.
Isosorbide dinitrate tablets, USP are supplied as: 5 mg: Round, pink, scored tablets, debossed GG 259 on one side and plain on the reverse side, and supplied as: Unit dose packages of 30 (5 x 6) NDC 68084-894-25 Store at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature].

ISOSORBIDE DINITRATE- ISOSORBIDE DINITRATE TABLET AMERICAN HEALTH PACKAGING ---------- ISOSORBIDE DINITRATE TABLETS, USP (ORAL) RX ONLY 8289421/0618F DESCRIPTION Isosorbide dinitrate (ISDN) is 1,4:3,6-dianhydro-D-glucitol 2,5-dinitrate, an organic nitrate whose structural formula is: The organic nitrates are vasodilators, active on both arteries and veins. Isosorbide dinitrate is a white, crystalline, odorless compound which is stable in air and in solution, has a melting point of 70°C and has an optical rotation of +134° (c=1, alcohol, 20°C). Isosorbide dinitrate is freely soluble in organic solvents such as acetone, alcohol, and ether, but is only sparingly soluble in water. Isosorbide dinitrate is available as 5 mg, 10 mg, and 20 mg tablets for oral administration. Inactive ingredients: lactose (monohydrate), magnesium stearate, microcrystalline cellulose. The 5 MG also contains FD & C Red #40 Aluminum Lake. The 20 MG also contains D & C Yellow #10 Aluminum Lake, FD & C Blue #1 Aluminum Lake, and FD & C Yellow #6 Aluminum Lake. CLINICAL PHARMACOLOGY The principal pharmacological action of isosorbide dinitrate is relaxation of vascular smooth muscle and consequent dilatation of peripheral arteries and veins, especially the latter. Dilatation of the veins promotes peripheral pooling of blood and decreases venous return to the heart, thereby reducing left ventricular end-diastolic pressure and pulmonary capillary wedge pressure (preload). Arteriolar relaxation reduces systemic vascular resistance, systolic arterial pressure, and mean arterial pressure (afterload). Dilatation of the coronary arteries also occurs. The relative importance of preload reduction, afterload reduction, and coronary dilatation remains undefined. Dosing regimens for most chronically used drugs are designed to provide plasma concentrations that are continuously greater than a minimally effective concentration. This strategy is inappropriate for organic nitrates. Several well-controlled clinical trials have used exercise testing to assess Soma hati kamili
