- Nitroglycerin forms free radical nitric oxide (NO), which in turn activates chemicals in the blood that cause smooth muscle to relax, resulting in vasodilation. Nitroglycerin is primarily metabolized by liver enzymes. Sublingual forms of nitroglycerin are absorbed quickly, in one to three minutes, with peak effects in about five to 10 minutes.
