Glyceryl trinitrate

Glyceryl trinitrate (GTN) sprays or tablets can help to relieve symptoms of angina.

How do they work? 

GTN quickly relaxes your blood vessels, allowing blood to flow more freely to your heart.

Ask your doctor or nurse to talk you through using an angina action plan to guide you when using GTN.

It's recommended that you sit down before using GTN, as you may experience headaches, flushing or dizziness soon after use. If taking a tablet, you may feel a slight tingling in your mouth - this is normal.

These are a range of medications that are used for this, including:
