Your glyceryl trinitrate (GTN) spray is a nitrate.
Nitrates relax your coronary arteries and allow the blood to reach the heart muscle more easily.
You may be on a number of other medications. It is important that you understand what medications you are taking and why you are taking them. If you are unsure, please ask your doctor, cardiac rehabilitation nurse or pharmacist.
