Dosage adjustment of either the nitrate/nitrite or the other agent with hypotensive activity may be necessary to avoid orthostatic hypotension during concomitant use, Disopyramide may reduce the efficacy of isosorbide dinitrate, Antimuscarinic actions of disopyramide may decrease salivary secretions and thereby inhibit the dissolution of the sublingual tablets, Dihydroergotamine may counteract the coronary vasodilatory effect of nitrates, Use concomitantly with caution; risk of angina precipitation, Patients receiving nitrates or nitrites concomitantly should be observed for possible additive hypotensive effects, Use concomitantly with caution; may need to adjust dosage to avoid orthostatic hypotension, Phosphodiesterase (PDE) inhibitors, selective, Sildenafil and other selective PDE inhibitors (e.g., tadalafil, vardenafil) profoundly potentiate the vasodilatory effects (e.g., a >25-mm Hg decrease in SBP) of organic nitrates and nitrites (e.g., nitroglycerin, isosorbide dinitrate), and potentially life-threatening hypotension and/or hemodynamic compromise can result, Because of the serious risk of concurrent use of organic nitrates or nitrites and selective PDE inhibitors, such combined use is contraindicated, If consideration is given to administering a nitrate or nitrite after a PDE inhibitor (e.g., >24 hours after sildenafil use), the response to the initial doses must be monitored carefully and proper facilities for fluid and vasopressor (e.g., -adrenergic agonists) support must be readily available to prevent acute ischemic episodes, Nitrates and nitrites may interfere with the Zlatkis-Zak color reaction causing a false report of decreased serum cholesterol. Both direct vasodilatory effects on the coronary bed and drug-induced prevention of episodic coronary artery vasoconstriction increase total coronary blood flow.
