Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
Nitroglycerin was written about as early as 1846 [5] [6] and came into medical use in 1878. [7] [8] [9] The drug nitroglycerin is a dilute form of the same chemical used as the explosive, nitroglycerin. [9] Dilution makes it non-explosive. [9]

The Middle Ages laid the ground work for later, more significant discoveries. There was a slow but constant progression in the way that medicine was studied and practiced.
The United States formed the American Pharmaceutical Association in 1852 [25] with its main purpose to advance pharmacists' roles in patient care, assist in furthering career development, spread information about tools and resources, and raising awareness about the roles of pharmacists and their contribution to patient care.
The pioneering work of the facial surgeon Gasparo Tagliacozzi in the 16th century marked one of the earliest attempts to surgically reconstruct nose defects. Before the invention of the free flap , only local tissue adjacent to the defect could be harvested for use, as the blood supply was a vital determining factor in the survival of the flap.
