Nitroglycerin 6.4 mg Controlled Release (CR) tablets are formulated to provide sustained anti-anginal protection throughout the day. Nitroglycerin belongs to the class of nitrate vasodilators that work by relaxing blood vessels, improving blood flow to the heart muscle, and reducing cardiac workload. The controlled-release (CR) formulation ensures gradual release of the medication, helping prevent episodes of angina pectoris (chest pain) caused by coronary artery disease. It is primarily used for long-term prophylaxis of angina rather than immediate relief of acute chest pain. Nitroglycerin converts to nitric oxide in the body, leading to vasodilation of both arteries and veins. This decreases myocardial oxygen demand and improves oxygen supply, reducing chest discomfort and improving exercise tolerance.
