GTN is a prodrug which must be denitrated, with the nitrite anion or a related species further reduced to produce the active metabolite nitric oxide (NO). 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… WebApr 14, 2024 · GTN works in two ways.
