🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Nitroglycerin is a nitrate that undergoes biotransformation to release nitric oxide (NO). NO activates guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP), which leads to smooth muscle relaxation. In vascular smooth muscle, this results in vasodilation, predominantly of veins, reducing preload and cardiac oxygen demand. At higher doses, it also dilates arteries, reducing afterload. In anal fissures, relaxation of the internal anal sphincter reduces spasm and pain, promoting healing.
