🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Nitroglycerin is a nitrate that works by releasing nitric oxide, which activates guanylate cyclase in smooth muscle cells. This leads to an increase in cyclic guanosine monophosphate (cGMP), causing smooth muscle relaxation. In the context of anal fissures, this relaxation reduces the resting pressure of the internal anal sphincter, which improves blood flow to the fissure and promotes healing. Additionally, the vasodilation effect can help reduce pain associated with sphincter spasm.
