Importance of warning all patients receiving organic nitrates or nitrites about the potential interaction between the drugs and selective PDE inhibitors, even if they currently are not receiving the drugs, since there is substantial potential for patients to receive the drugs from another clinician, from a friend, with little or no clinical intervention (e.g., via the Internet), or illicitly. The observed clearance rates (close to 1 L/kg/min) greatly exceed hepatic blood flow; known sites of extrahepatic metabolism include red blood cells and vascular walls.

Sublingual or intrabuccal nitrates may be inadequately absorbed, with resultant decreased efficacy, in patients with dry oral mucous membranes (e.g., xerostomia). Isosorbide dinitrate or mononitrate is used for the acute relief of angina pectoris, for prophylactic management in situations likely to provoke angina attacks, and for long-term prophylactic management of angina pectoris. Avoid or Use Alternate Drug. If a -blocker is not effective in controlling chronic stable angina, long-acting nitrates may be added to -blocker therapy. We comply with the HONcode standard for trustworthy health information. Avoid or Use Alternate Drug. It does not work fast enough to relieve the pain of an angina attack that has already started. affecting hepatic/intestinal enzyme CYP3A4 metabolism. Contraindicated. Controlled studies in pregnant women show no evidence of fetal risk. Importance of instructing patients receiving isosorbide dinitrate for relief of acute attacks of angina pectoris to consult a clinician or go to a hospital emergency room immediately if chest pain is not relieved after 3 doses approximately every 5 minutes, because inability to relieve chest pain may indicate acute MI. Isosorbide dinitrate conventional tablets, peak: 60 minutes. Isosorbide dinitrate fixed-combination tablets with hydralazine hydrochloride, peak: 60 minutes. Do not use extended-release isosorbide dinitrate preparations or any isosorbide mononitrate preparation to abort an acute anginal episode or for acute relief of angina or in the prophylactic management in situations likely to provoke angina attacks; onset is not sufficiently rapid. affecting hepatic/intestinal enzyme CYP3A4 metabolism. Careful clinical or hemodynamic monitoring for possible hypotension or tachycardia if used in acute MI or heart failure. In addition to vascular smooth muscle, nitrates and nitrites relax bronchial, biliary (including the gallbladder, biliary ducts, and sphincter of Oddi), GI (including the esophagus), ureteral, and uterine smooth muscle; nitrates relax all smooth muscle irrespective of autonomic innervation and are functional antagonists of norepinephrine, acetylcholine, and histamine. commonly, these are "preferred" (on formulary) brand drugs. Coadministration with duvelisib increases AUC of a sensitive CYP3A4 substrate which may increase the risk of toxicities of these drugs. Isosorbide mononitrate: Generally, food delays the rate but not the extent of absorption (less than 10%) of conventional or extended-release tablets. Prophylactic management in situations likely to provoke angina attacks in patients who fail to respond to sublingual nitroglycerin: 2.55 mg of isosorbide dinitrate should be placed under the tongue approximately 15 minutes prior to engaging in such activities. Isosorbide dinitrate: Food may decrease substantially mean peak plasma concentrations, yet total bioavailability does not seem to be affected. Selective PDE inhibitors can potentiate the hypotensive effects of organic nitrates and nitrites, possibly resulting in potentially life-threatening hypotension and/or hemodynamic compromise. Sign Up Increase dose of CYP3A4 substrate, as needed, when coadministered with cenobamate.

Adjust dose of drugs that are CYP3A4 substrates as necessary. Employ intermittent dosing of nitrates (e.g., use of a nitrate-free interval of 1012 hours daily) to minimize or prevent the development of tolerance to the hemodynamic and antianginal effects of the drugs.
