It is made by the action of nitric acid on glycerin in the presence of sulphuric acid. It is extremely unstable and terribly explosive. A very dilute solution is used in medicine as a neurotic under the name of glonion. A great number of explosive compounds have been produced by mixing nitroglycerin with different substances; as, dynamite, or giant powder, nitroglycerin mixed with siliceous earth; lithofracteur, nitroglycerin with gunpowder, or with sawdust and nitrate of sodium or barium; Colonia powder, gunpowder with nitroglycerin; dualin, nitroglycerin with sawdust, or with sawdust and nitrate of potassium and some other substances; lignose, wood fibre and nitroglycerin. Pharmacologic action: Relaxes smooth muscle - dilates veins, dilates coronary arteries, reduces left ventricular filling pressure, lowers systemic vascular resistance, decreases myocardial oxygen demand. Uses: Treat angina pectoris. Dose: One tablet (0.3 to 0.4 mg) sublingual, may repeat twice at 5 minute intervals Intravenous infusion: 0.5 - 2 mcg/kg per min. Potential complications: May cause hypotension, especially if hypovolemic; headache is common. Alternative forms: nitroglycerine. Origin: Nitro- + glycerinn. (17 Mar 2000)
