Consumer Information

This information was provided by the drug’s manufacturer when this drug product was approved for sale in Canada. It is designed for consumers and care givers. It is a summary of information about the drug and will not tell you everything about the drug. Contact your doctor or pharmacist if you have any questions about the drug.

What the medication is used for

NITRO-DUR is used in adults to prevent angina (chest pain).

NITRO-DUR is NOT intended to be used for acute angina attacks. Sublingual nitroglycerin medications should be used if you are having an acute angina attack.

What it does

NITRO-DUR is a patch applied directly to the skin. The nitroglycerin passes from the adhesive surface through the skin - allowing medication to be absorbed directly into the bloodstream. Nitroglycerin causes the blood vessels to relax and increases the supply of blood and oxygen to the heart reducing the likeliness of having an angina attack.

The amount of NITRO-DUR you need will depend upon your body's needs. Observe the dosing instructions given to you by your prescribing physician and report to him/her if your condition changes.

When it should not be used

What the medicinal ingredient is

Nitroglycerin

What the non-medicinal ingredients are

Polymers used mainly in the adhesive of the patch.

What dosage form it comes in

Transdermal patch: 40 mg (0.2 mg/hour), 80 mg (0.4 mg/hour), 120 mg (0.6 mg/hour), 160 mg (0.8 mg/hour)
