Nitroglycerin 6.4 mg Controlled Release (CR) tablet is a long-acting nitrate formulation used in the prevention of angina pectoris (chest pain) associated with coronary artery disease. Nitroglycerin works by relaxing and widening blood vessels (vasodilation), which improves blood flow to the heart muscle and reduces its oxygen demand. The controlled-release technology ensures gradual and sustained release of nitroglycerin over an extended period, helping to prevent angina attacks throughout the day. It is primarily used for prophylactic management and not for immediate relief of acute chest pain. This medication helps reduce the frequency, severity, and duration of angina episodes and improves exercise tolerance in patients with ischemic heart disease.
