Description
💓 Nitroglycerin 2.6mg Sublingual Tablet
Fast-Acting Relief for Angina and Chest Pain
Introduction:
Nitroglycerin 2.6mg is a rapid-onset medication widely used to relieve angina pectoris—the chest pain or discomfort caused by reduced blood flow to the heart muscle. This sublingual tablet acts quickly to dilate blood vessels, improving blood and oxygen supply to the heart, thereby easing symptoms of angina. It is a cornerstone in the emergency management of acute chest pain episodes.
Mechanism of Action:
Nitroglycerin belongs to a class of drugs called nitrates, which work by releasing nitric oxide (NO) in the body. This leads to the relaxation of smooth muscles in blood vessel walls, causing vasodilation (widening of blood vessels). Vasodilation reduces the workload on the heart by decreasing both preload and afterload—the volume of blood returning to the heart and the resistance the heart must pump against. The net effect is improved blood flow to the heart muscle and relief from angina symptoms.
Indications:
-
Relief and prevention of angina pectoris (chest pain) due to coronary artery disease

Treatment of acute episodes of chest pain
-
Used prophylactically before activities known to trigger angina (e.g., exercise)
Dosage and Administration:
