Nitroglycerin

Nitroglycerin is a medication primarily used to treat and prevent chest pain (angina) associated with heart disease. It belongs to a class of drugs called nitrates and works by relaxing and widening blood vessels. This helps increase the blood flow to the heart, reducing the strain on the heart and relieving pain. Nitroglycerin can be administered in various forms, including tablets, sprays, and patches, depending on the severity of the condition.
