Nitroglycerin: Uses, Interactions, Mechanism of Action

WebMechanisms of Action Organic nitrates are prodrugs that must undergo enzymatic denitrification to mediate their pharmacodynamic effects ( Figures 7-1 and 7-2 ). In 1977, Murad first suggested that nitric oxide (NO) mediated the effects of GTN. 5 Since that time, it has generally been accepted that all the organic nitrates exert their effects ... WebNitroglycerin (NG), (alternative spelling of nitroglycerine) also known as trinitroglycerin (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester. ... WebThe mechanisms underlying vasodilation include intracellular bioactivation of the nitrates (IDN to IMN in the liver, GTN by vascular mitochondrial aldehyde dehydrogenase), the release of NO, and activation of the enzyme soluble guanylyl cyclase. option 405

Organic nitrates that undergo these two steps within the body are called nitrovasodilators, and the denitration and reduction occur via a variety of mechanisms. The mechanism by which such nitrates produce NO is widely disputed. Some believe that organic nitrates produce NO by reacting with sulfhydryl groups, while others believe t…

WebA new class of drugs, soluble guanylyl cyclase (sGC) stimulators, directly activates sGC to produce cGMP. As described above, sGC is the enzyme that is activated by nitric oxide and nitrodilators to form cGMP, which produces vasodilation. By directly activating sGC, sGC stimulators mimic the effects of nitrodilators.
