Angina pectoris: Oral: Note: Tolerance to nitrate effects develops with chronic exposure. Dose escalation does not overcome this effect. Tolerance can only be overcome by short periods of nitrate absence from the body. Recommended twice daily dosage regimens incorporate this interval. Short periods of nitrate withdrawal may help minimize tolerance.
Immediate release: 20 mg twice daily with the 2 doses given 7 hours apart (eg, 8 AM and 3 PM) to decrease tolerance development; patients with small stature may initiate therapy with 5 mg twice daily and titrate to at least 10 mg twice daily in first 2 to 3 days of therapy.
Extended release: Initial: 30 to 60 mg once daily in the morning; may titrate after several days to 120 mg once daily; rarely, 240 mg once daily may be required
Heart failure with reduced ejection fraction (off-label use): Note: As additional therapy for persistent NYHA class III or IV heart failure with reduced ejection fraction (HFrEF) despite optimal medical therapies or for patients who cannot tolerate an ACE inhibitor, angiotensin II receptor blocker (ARB), or angiotensin II-neprilysin inhibitor (ARNI). Although ACCF/AHA guidelines recommend isosorbide dinitrate with hydralazine, some experts substitute isosorbide mononitrate for isosorbide dinitrate to reduce pill burden and improve adherence (ACC/AHA/HFSA [Yancy 2017]; ACCF/AHA [Yancy 2013]; Colucci 2018; Gottlieb 2018).
Oral: Extended release: Initial: 30 to 60 mg once daily in combination with hydralazine 3 or 4 times daily; titrate dose every 2 to 4 weeks; maximum dose: 120 mg/day (Gottlieb 2018). Note: May also consider use of the fixed-dose combination of isosorbide dinitrate/hydralazine instead of separate components (ACC/AHA/HFSA [Yancy 2017]; ACCF/AHA [Yancy 2013]).
Refer to adult dosing; initiate with lowest recommended dose.
No dosage adjustment necessary.
Hemodialysis: Supplemental dose is not necessary. Dose after dialysis (Aronoff 2007)
Continuous ambulatory peritoneal dialysis: Supplemental dose is not necessary.
No dosage adjustment necessary.
Angina pectoris: Treatment (immediate-release only) and prevention of angina pectoris caused by coronary artery disease. Note: The onset of action of oral isosorbide mononitrate is not sufficiently rapid for this product to be useful in aborting an acute anginal episode.
Heart failure with reduced ejection fraction (HFrEF)Level of Evidence [C]
Based on the American College of Cardiology Foundation/American Heart Association (ACCF/AHA) guidelines for the management of heart failure, isosorbide dinitrate (in combination with hydralazine) is effective and recommended as additional therapy to optimal guideline directed medical therapy for self-identified African-American patients with persistent NYHA class III or IV HFrEF or for patients who do not tolerate an ACE inhibitor or an angiotensin II receptor blocker (ARB). Some experts recommend isosorbide dinitrate (in combination with hydralazine) in addition to optimal guideline-directed medical therapy for black and nonblack patients with persistent NYHA class III or IV HFrEF, particularly for those with low output states or hypertension, or for patients who do not tolerate an ACE inhibitor, ARB, or angiotensin II-neprilysin inhibitor (ARNI). In order to improve compliance, it may be reasonable to replace isosorbide dinitrate with isosorbide mononitrate (in combination with hydralazine) Ref.

Do not administer around-the-clock. Immediate release tablet should be scheduled twice daily with doses 7 hours apart (8 AM and 3 PM); administer extended release tablet once daily in the morning upon rising with a half-glassful of fluid. Do not chew or crush extended release tablets; may be divided in half. Due to insoluble matrix embedding, extended release tablets that are scored may be split (Gunasekara 1999).
Store at 25°C (77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Protect from moisture.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience headache. Have patient report immediately to prescriber angina, severe dizziness, passing out, bradycardia, or tachycardia (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for healthcare professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience and judgment in diagnosing, treating and advising patients.
Sound-alike/look-alike issues: Geriatric Patients: High-Risk Medication:Hypersensitivity to isosorbide mononitrate, other nitrates or nitrites, or any component of the formulation; concurrent use with phosphodiesterase-5 (PDE-5) inhibitors (sildenafil, tadalafil, or vardenafil) or riociguat.
Canadian labeling: Additional contraindications (not in US labeling): Acute circulatory failure associated with marked hypotension (shock and states of collapse); postural hypotension; myocardial insufficiency due to obstruction (eg, in the presence of aortic or mitral stenosis or of constrictive pericarditis); increased intracranial pressure; severe anemia.
Concerns related to adverse effects:
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery or driving).
• Hypotension/bradycardia: Severe hypotension can occur; paradoxical bradycardia and increased angina pectoris can accompany hypotension. Orthostatic hypotension can also occur; ethanol can accentuate this. Severe hypotension, particularly with upright posture, may occur with even small doses.
• Intracranial pressure increased: Nitrates may precipitate or aggravate increased intracranial pressure and subsequently may worsen clinical outcomes in patients with neurologic injury (eg, intracranial hemorrhage, traumatic brain injury) (Rangel-Castilla 2008).
Disease-related concerns:
• Cardiovascular disease: Not recommended for use in patients with acute myocardial infarction (MI) or heart failure (has not been studied). Use with caution in volume depletion and moderate hypotension, and with extreme caution with inferior wall MI and suspected right ventricular infarctions. The Canadian labeling contraindicates use in acute circulatory failure associated with marked hypotension, postural hypotension, and myocardial insufficiency due to obstruction (eg, in the presence of aortic or mitral stenosis or of constrictive pericarditis).
• Hypertrophic cardiomyopathy (HCM): Avoid use in patients with HCM with outflow tract obstruction; nitrates may reduce preload, exacerbating obstruction and cause hypotension or syncope and/or worsening of heart failure (Gersh 2011).
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• PDE-5 inhibitors: Avoid concurrent use with PDE-5 inhibitors (eg, sildenafil, tadalafil, vardenafil). When nitrate administration becomes medically necessary, may administer nitrates only if 24 hours have elapsed after use of sildenafil or vardenafil (48 hours after tadalafil use) (O’Connor 2010).
Dosage forms related issues:
• Extended-release tablets: Empty matrix “ghosts” (tablets) may pass in patients via colostomy or in the stool; this is of no concern.
Other warnings/precautions:
• Appropriate use: Extended-release: Not intended for the immediate relief of acute attacks of angina pectoris.
• Tolerance: Appropriate dosing intervals are needed to minimize tolerance development. Tolerance can only be overcome by short periods of nitrate absence from the body. Dose escalation does not overcome this effect.
The first dose of nitrates (sublingual, chewable, oral) should be taken in a physician’s office to observe for maximal cardiovascular dynamic effects and adverse effects (eg, orthostatic blood pressure drop, headache). The use of nitrates for angina may occasionally promote reflux esophagitis. This may require dose adjustments or changing therapeutic agents to correct this adverse effect.

Adverse events have been observed in some animal reproduction studies. Nitric oxide donors, such as isosorbide, have been evaluated for pre-eclampsia and cervical ripening; isosorbide mononitrate use in these conditions is not currently recommended (Kalidindi 2012; Ramirez 2011).
It is not known if isosorbide mononitrate is excreted in breast milk. The manufacturer recommends that caution be exercised when administering isosorbide mononitrate to nursing women.

Nitroglycerin and other nitrates form free radical nitric oxide. In smooth muscle, nitric oxide activates guanylate cyclase which increases guanosine 3’5’ monophosphate (cGMP) leading to dephosphorylation of myosin light chains and smooth muscle relaxation. Produces a vasodilator effect on the peripheral veins and arteries with more prominent effects on the veins. Primarily reduces cardiac oxygen demand by decreasing preload (left ventricular end-diastolic pressure); may modestly reduce afterload; dilates coronary arteries and improves collateral flow to ischemic regions.
