Adverse Effects
Frequency Not Defined
Cardiovascular: Rebound hypertension (uncommon), syncope, unstable angina flushing, hypotension/orthostatic hypotension, lightheadedness, palpitations, tachyarrhythmia
Central nervous system (CNS): Dizziness, headache, restlessness, weakness
Gastrointestinal (GI): Nausea
Hematologic: Methemoglobinemia (infrequent)
Warnings
Contraindications
Hypersensitivity
Recent use (within several days) of PDE-5 inhibitors (eg, avanafil, sildenafil, tadalafil, or vardenafil) may cause dangerously low hypotension; the time course of the interaction appears to be related to the PDE-5 inhibitor half-life
Severe anemia, shock, markedly low blood pressure (BP)
Concomitant administration with guanylate stimulator riociguat
Cautions
Allergies to nitrates, head trauma/cerebral hemorrhage (potential contraindication), hypertrophic cardiomyopathy, increased intraocular pressure, postural hypotension, acute myocardial infarction (MI), congestive heart failure, hyperthyroidism
Inability to relieve chest pain after 3 doses may signal acute MI necessitating emergency management
Tolerance to extended-release formulation may develop, rendering formulation ineffective after a few weeks
Do not change brands unintentionally; formulations are not all bioequivalent
Severe hypotension, particularly with upright posture, may occur with even small doses; use with caution in patients who may be volume depleted or who are already hypotensive; hypotension induced by isosorbide dinitrate may be accompanied by paradoxical bradycardia and increased angina pectoris
Nitrate therapy may aggravate angina caused by hypertrophic cardiomyopathy
Treat drug-induced headache with aspirin or acetaminophen
Provide nitrate-free interval (10-12 hours or overnight) to prevent development of tolerance
Use supportive treatment in overdose
Avoid use of extended release formulation in acute MI or acute heart failure; adverse events are not easily reversible if they develop
Avoid use in patients with hypertrophic cardiomyopathy with outflow tract obstruction; nitrates may reduce preload, which may cause exacerbation of obstruction and cause hypotension or syncope and/or worsening of heart failure
Pregnancy & Lactation
Pregnancy category: C
Lactation: Unknown whether drug is distributed into breast milk
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

Absorption
~100% absorbed from GI tract or oral mucosa
Bioavailability: Immediate release, 40-50%
Duration: 1-2 hr
Distribution
Vd: 2-4 L/kg
Metabolism
Extensively metabolized in liver to conjugated metabolites

ISOSORBIDE DINITRATE - ORAL
(EYE-soe-SOR-bide dye-NYE-trate)
COMMON BRAND NAME(S): Isordil
USES: Isosorbide dinitrate is used to prevent chest pain (angina) in patients with a certain heart condition (coronary artery disease). This medication belongs to a class of drugs known as nitrates. It works by relaxing and widening blood vessels so blood can flow more easily to the heart.This medication will not relieve chest pain once it occurs. It is also not intended to be taken just before physical activities (such as exercise, sexual activity) to prevent chest pain. Other medications may be needed in these situations. Consult your doctor for more details.
HOW TO USE: Take this medication by mouth as directed by your doctor, usually 2 to 3 times daily. It is important to take the drug at the same times each day. Do not change the dosing times unless directed by your doctor.Use this medication regularly to get the most benefit from it. Do not suddenly stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.Although unlikely, when this medication is used for a long time, it may not work as well and may require different dosing. Tell your doctor if this medication stops working well (for example, you have worsening chest pain or it occurs more often).
SIDE EFFECTS: Headache, dizziness, lightheadedness, nausea, and flushing may occur as your body adjusts to this medication. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Headache is often a sign that this medication is working. Your doctor may recommend treating headaches with an over-the-counter pain reliever (such as acetaminophen, aspirin). If the headaches continue or become severe, tell your doctor promptly.To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: fainting, fast/irregular/pounding heartbeat.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before taking this medication, tell your doctor or pharmacist if you are allergic to it; or to similar drugs (such as isosorbide mononitrate, nitroglycerin); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: recent head injury, anemia, low blood pressure, dehydration, other heart problems (such as recent heart attack).This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Older adults may be more sensitive to the side effects of this medication, especially dizziness and lightheadedness, which could increase the risk of falls.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this medication passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Some products that may interact with this drug include: drugs to treat erectile dysfunction-ED or pulmonary hypertension (such as sildenafil, tadalafil), certain drugs to treat migraine headaches (ergot alkaloids such as ergotamine), riociguat, vericiguat.Some products have ingredients that could worsen your heart failure. Tell your pharmacist what products you are using, and ask how to use them safely (especially cough-and-cold products, diet aids, or NSAIDs such as ibuprofen/naproxen).Isosorbide dinitrate is very similar to isosorbide mononitrate. Do not use medications containing isosorbide mononitrate while using isosorbide dinitrate.This medication may interfere with certain lab tests (such as blood cholesterol levels), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.
