What is the mechanism of action of nitroglycerin?
Mechanism of Action: Nitroglycerin forms free radical nitric oxide (NO) which activates guanylate cyclase, resulting in an increase of guanosine 3’5′ monophosphate (cyclic GMP) in smooth muscle and other tissues.
How does Nitro Dur work?
Nitroglycerin belongs to the group of medicines called nitrates. It works by relaxing the blood vessels and increasing the supply of blood and oxygen to the heart while reducing its work load. When used regularly on a long-term basis, this helps prevent angina attacks from occurring.

What is the mechanism of action of nitrates?
Mechanism of action of nitrates Mechanism of action of nitrates: Nitrates get metabolised to form nitric oxide, which is a potent vasodilator. Nitric oxide is also the endothelium derived relaxing factor. Nitric oxide stimulates the enzyme guanylate cyclase, which causes the synthesis of cyclic guanosine monophosphate (cGMP).
How does the Nitro Dur transdermal system work?
The NITRO-DUR transdermal system contains nitroglycerin in acrylic-based polymer adhesives with a resinous cross-linking agent to provide a continuous source of active ingredient. Each unit is sealed in a paper polyethylene-foil pouch. Cross section of the system. Indications & Dosage INDICATIONS
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 does nitroglycerin do to the smooth muscles?
Nitroglycerin causes the relaxation of vascular smooth muscles, causing arteriolar and venous dilatation.
