View company portfolio →What GLYRATE-SR (Nitroglycerin (glyceryl trinitrate, GTN)) is used for
Nitroglycerin, also called glyceryl trinitrate or GTN, is a medicine from a group called nitrates. It relaxes and widens blood vessels. This lets more blood and oxygen reach the heart and makes the heart's work easier, which eases chest pain from angina. It comes as tablets that dissolve under the tongue, a spray used under the tongue, and skin patches. There is also an ointment for the bottom, and a drip given in hospital.
- Quickly easing an angina attack (chest pain caused when the heart muscle does not get enough blood) once it has started, using the under-the-tongue tablets or spray
- Preventing angina just before an activity that is likely to bring it on, such as exercise, stress or going out in the cold
- Helping to prevent angina attacks over time, using skin patches
- Anal fissures (small, painful tears in the skin around the bottom), using a rectal ointment on prescription
- In hospital, patches are sometimes used to make veins easier to find before a drip
Get medical help straight away if
- Call an ambulance straight away if your angina pain does not go away after using GTN the way your doctor told you, or if it gets worse or you feel unwell. This may be a heart attack. Do not drive yourself to hospital.
- Call an ambulance or go to the emergency department for chest pain that is different from or worse than your usual angina, new or worse breathing problems, a heartbeat much faster or slower than normal, or fainting.
- Get emergency help if your lips, tongue, face or skin look blue or grey. On brown or black skin, look at the gums, tongue, lips or around the eyes.
- Get emergency help for signs of a severe allergic reaction: swelling of the lips, mouth, tongue or throat, wheezing or struggling to breathe, a tight throat, or sudden confusion or fainting.
