What is the mechanism of action of nitroglycerin?
Nitroglycerin works by relaxing the muscles surrounding blood vessels (arteries and veins) and so helps more blood and oxygen reach the heart while reducing its work load. When used regularly on a long-term basis, or just before exercise or a stressful event, sublingual nitroglycerin helps prevent angina attacks from occurring.
What happens if nitroglycerin is allowed to dry out?
If allowed to dry out, the remaining nitroglycerin is explosive. Nitroglycerin, desensitized, [liquid] appears as a pale yellow, viscous liquid that is slightly soluble in water and more dense than water. Sensitive to shock and heat. May explode under prolonged exposure to fire or heat.
What happens to nitroglycerin during an angina attack?
The body breaks nitroglycerin down into nitric oxide. Nitric oxide causes the smooth muscle within the blood vessels to relax. This allows the arteries and veins to open up, allowing more blood to flow through. Healthcare professionals call this action vasodilation. During an angina attack, a person will experience intense chest pain.
What’s the proper route to take nitroglycerin tablets?
Do not drive yourself to the hospital. Nitroglycerin sublingual tablets should not be chewed, crushed, or swallowed. They work much faster when absorbed through the lining of the mouth. Place the tablet under the tongue or between the cheek and gum, and let it dissolve. Do not eat, drink, smoke, or use chewing tobacco while a tablet is dissolving.
