Another commonly used name for nitroglycerin is glyceryl trinitrate . When applied to the skin, nitrates are used to reduce the number of angina attacks that occur.
Topical nitroglycerin is absorbed through the skin.
It works by relaxing blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. This helps prevent future angina attacks from occurring. Topical nitroglycerin may also be used for other conditions as determined by your doctor. In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make.
