Nitroglycerin, as a highly sensitive explosive and strictly regulated drug, is subject to extremely high safety and regulatory restrictions in its production.
Nitroglycerin is a vasodilator widely used in the treatment of angina pectoris and heart failure. Common dosage forms include patch, spray, injection and ointment. Although it is very important in clinical practice, due to its extremely unstable chemical properties and susceptibility to explosions, industrial production must be carried out in a highly controlled environment, usually by qualified large pharmaceutical companies.

Nitroglycerin is produced industrially by nitration of glycerol using a mixture of concentrated nitric acid and concentrated sulfuric acid.
The production line includes mixing, cooling, separation, washing, and stabilization processes, and all equipment must be explosion-proof and use non sparking tools
