[2] Isosorbide mononitrate and isosorbide dinitrate are important medications for some heart diseases. Congestive heart failure: Oral: Initial: 10 mg 3 times/day. Trade Name. Isosorbide Mononitrate (ISMN), an organic nitrate and the major biologically active metabolite of isosorbide dinitrate (ISDN), is a vasodilator with effects on both arteries and veins. Below is a conversion table to enable using this preparation in place of standard release isosorbide mononitrate and modified release (M/R) preparations which are not going to be kept. If you take isosorbide mononitrate or dinitrate 2 or 3 times a day, your doctor or pharmacist will explain how to space out your doses. Principal pharmacologic property is relaxation of vascular smooth muscle, resulting in generalized vasodilation. Concomitant use of isosorbide with PDE inhibitors will cause increased cGMP, resulting in life-threatening hypotension. Prescription only. It is not FDA-approved for treating heart failure. Isosorbide dinitrate has been used effectively for diffuse esophageal spasm [off-label] without gastroesophageal reflux to relieve pain, dysphagia, and spasm. Both direct vasodilatory effects on the coronary bed and drug-induced prevention of episodic coronary artery vasoconstriction increase total coronary blood flow. Other adverse effects can be due to the reflex activity of the sympathetic nervous system due to vasodilation. 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. This effect is nitrate -specific and is not seen with non- nitrate sources of nitric oxide such . If you have been taking it regularly and you stop taking it, your angina symptoms or heart failure may get worse. Target: 40 mg 3 times/day. 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. Initially, isosorbide dinitrate 20 mg and hydralazine hydrochloride 37.5 mg (1 tablet of BiDil) 3 times daily. However, this may be hazardous in renal failure and congestive heart failure patients. Tell your doctor or pharmacist if you have: Take isosorbide mononitrate and dinitrate exactly as your doctor or pharmacist tells you to. Isosorbide dinitrate dose 30-120 mg daily in divided doses. In conclusion, in patients with heart failure with a preserved ejection fraction, the receipt of isosorbide mononitrate, as compared with placebo, decreased daily activity levels. If this happens to you, do not drive, ride a bike or use tools or operate machinery until you feel better. <> You can report any suspected side effect using the Yellow Card safety scheme. Rapid titration (over 35 days) may be possible; however, slower titration may be needed due to adverse effects. Isosorbide mononitrate (Monoket) is good for a specific type of chest pain (called angina), but it can cause headaches or dizziness after you take it. Conventional oral tablets: 25% unchanged drug; about half that following sublingual administration (4050%). This means you do not need to take them as often as standard tablets. Manufacturers of selective PDE inhibitors (e.g., sildenafil, tadalafil, vardenafil) state that the drugs are contraindicated in patients receiving organic nitrates or nitrites in any form (e.g., orally, sublingually, transmucosally, parenterally), given regularly or intermittently, or nitric oxide donors since severe, potentially fatal hypotensive episodes can occur. Visit Yellow Card for further information. Extended-release oral nitrate preparations should not be used in patients with functional or organic GI hypermotility or malabsorption syndrome. In heart failure, isosorbide mononitrate and dinitrate relaxes the blood vessels, making it easier for your heart to pump blood around your body. 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. Isosorbide mononitrate and dinitrate can make some people feel dizzy, sleepy or faint. Titrate dosages to levels similar to those recommended for the fixed-combination preparation and administer both drugs at least 3 times daily. Prophylactic management in situations likely to provoke angina attacks in patients who fail to respond to sublingual nitroglycerin: place 2.55 mg of isosorbide dinitrate under the tongue about 15 minutes prior to engaging in such activities. We can use this medication to both treat and prevent heart-related chest pain. Pleiotropic regulation of vascular smooth muscle tone by cyclic GMP-dependent protein kinase.

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. An interdosing interval sufficient to avoid tolerance to Dilatrate-SR extended-release capsules is not known, but it must exceed 18 hours. ISDN allows you to exercise for up to eight hours. Furthermore, there can be some severe effects as well, which include low blood pressure when exposed to PDE5 inhibitors, e.g. "[~ In patients with hypertrophic cardiomyopathy, isosorbide decreases the preload and, hence, the left ventricular volume, worseningleft ventricular outflow tract obstruction.[11]. The venodilation results in peripheral pooling of blood and arteriolar dilation, lowering systemic vascular resistance (afterload) and lowering blood pressure.
