ni·tro·glyc·er·in (ni″tro-glisґər-in) a colorless to yellow liquid formed by the action of nitric and sulfuric acids on glycerin. It explodes on concussion, but is safe if diluted with inert excipients. Exposure to excessive amounts causes headache, blurred vision, vomiting, hypotension, and syncope, and possibly cyanosis and methemoglobinemia. Prolonged exposure causes tolerance, and abrupt discontinuation can cause withdrawal symptoms. [USP] a pharmaceutical preparation of nitroglycerin, diluted with lactose, dextrose, alcohol, propylene glycol, or other excipient for safety and officially called diluted nitroglycerin; it has antianginal, antihypertensive, and vasodilator properties and is used in medicine for the prophylaxis and treatment of angina pectoris, the treatment of congestive heart failure, as an adjunct in the treatment of myocardial infarction, and for blood pressure control or controlled hypotension during surgery. Administered by absorption through the oral mucous membranes, orally, intravenously, topically, or with a transdermal patch.
