What is nitroglycerin transdermal (minitran, nitrek, nitro td patch-a, nitro-dur)?
Nitroglycerin is in a group of drugs called nitrates. Nitroglycerin dilates (widens) blood vessels, making it easier for blood to flow through them and easier for the heart to pump.
Nitroglycerin transdermal is used to prevent attacks of chest pain (angina).
Nitroglycerin transdermal may also be used for purposes not listed in this medication guide.
What should i discuss with my healthcare provider before using nitroglycerin transdermal (minitran, nitrek, nitro td patch-a, nitro-dur)?
You should not use this medication if you are allergic to nitroglycerin, isosorbide mononitrate (Imdur), or isosorbide dinitrate (BiDil, Isordil). Do not use nitroglycerin transdermal if you are allergic to any type of adhesive on a bandage or other transdermal skin patch.
To make sure you can safely use nitroglycerin, tell your doctor if you have any of these other conditions:
- congestive heart failure;
- a history of heart attack, stroke, or head injury;
- low blood pressure;
- glaucoma; or
- anemia (lack of red blood cells).
FDA pregnancy category C. It is not known whether nitroglycerin will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant while using this medication.
It is not known whether nitroglycerin transdermal passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Nitroglycerin is a prescription medication used to treat or prevent episodes of angina (sudden chest pain). Nitroglycerin belongs to a group of drugs called nitrates which work by relaxing (widening) blood vessels making it easier for the heart to pump blood.
This medication comes in tablet form to be dissolved under the tongue or between the cheek and gum at the first sign of chest pain. The dose may be repeated every 5 minutes until chest pain is relieved. Seek emergency medical attention if the pain persists after 3 doses.
Common side effects of nitroglycerin include headache, dizziness, and weakness.
Side Effects of Transderm-Nitro
Nitroglycerin may cause the following side effects:
- vertigo (a major symptom of balance disorder)
- heart palpitations (unusual awareness of the heartbeat)
- low blood pressure upon rising from a seated position
- nausea and vomiting
- flushing (warm or red condition of your skin)
- other skin reactions that may be severe
Nitroglycerin may cause a false test result of decreased serum cholesterol.
Tell your doctor if you are concerned about any side effects you experience. These are not all the possible side effects of nitroglycerin. For a complete list, ask your doctor or pharmacist.
Nitroglycerin should be kept in the original glass container and tightly capped after each use to prevent loss of tablet potency.
Store nitroglycerin tablets at room temperature (between 68° and 77°F).
Adverse reactions to nitroglycerin are generally dose-related, and almost all of these reactions are the result of nitroglycerin’s activity as a vasodilator. Headache, which may be severe, is the most commonly reported side effect. Headache may be recurrent with each daily dose, especially at higher doses. Transient episodes of lightheadedness, occasionally related to blood pressure changes, may also occur. Hypotension occurs infrequently, but in some patients it may be severe enough to warrant discontinuation of therapy. Syncope, crescendo angina, and rebound hypertension have been reported but are uncommon.
Allergic reactions to nitroglycerin are also uncommon, and the great majority of those reported have been cases of contact dermatitis or fixed drug eruptions in patients receiving nitroglycerin in ointments or patches. There have been a few reports of genuine anaphylactoid reactions, and these reactions can probably occur in patients receiving nitroglycerin by any route.
Extremely rarely, ordinary doses of organic nitrates have caused methemoglobinemia in normal-seeming patients. Methemoglobinemia is so infrequent at these doses that further discussion of its diagnosis and treatment is deferred (see OVERDOSAGE).
Application-site irritation may occur but is rarely severe.
In two placebo-controlled trials of intermittent therapy with nitroglycerin patches at 0.2 to 0.8 mg/hr, the most frequent adverse reactions among 307 subjects were as follows:
|Hypotension, and/or syncope||0%||4%|

Appropriate studies have not been performed on the relationship of age to the effects of nitroglycerin transdermal in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of nitroglycerin transdermal in the elderly. However, elderly patients are more likely to have low blood pressure and age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving nitroglycerin transdermal.
