Nitroglycerine
Introduction
Nitroglycerine is a well-known medication used primarily to treat and prevent chest pain (angina) related to heart disease. It belongs to a class of drugs known as nitrates and works by relaxing blood vessels, allowing blood to flow more easily to the heart. Nitroglycerine helps reduce the heart's workload and oxygen demand. It is available in several forms, including tablets, sprays, and patches, and is often used in emergency situations or long-term heart management plans.
