Nitroglycerin, also known as glyceryl trinitrate (GTN), is a vasodilator used for heart failure, high blood pressure (hypertension), anal fissures, painful periods, and to treat and prevent chest pain caused by decreased blood flow to the heart or due to the recreational use of cocaine.
Patients with known coronary artery disease who have been prescribed nitroglycerin should promptly take one dose, and call emergency medical services if their symptoms do not improve within 2–5 minutes. Chewing non−enteric-coated aspirin is encouraged (unless there are contraindications). Patients should stay calmed in a comfortable position.
Sublingual nitroglycerin is used for acute coronary syndrome; Isosorbide mononitrate and isosorbide dinitrate are used for symptomatic relief when blood pressure <130/80 mmHg [17] Not to be used as monotherapy in chronic coronary syndrome; An image of sublingual nitroglycerin tablets (Nitrostat) Caution. Avoid concomitant use of PDE-5 inhibitors
A nitrovasodilator is a pharmaceutical agent that causes vasodilation (widening of blood vessels) by donation of nitric oxide (NO), [1] and is mostly used for the treatment and prevention of angina pectoris.
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.
Sodium nitroprusside (SNP), sold under the brand name Nitropress among others, is a medication used to lower blood pressure. [3] This may be done if the blood pressure is very high and resulting in symptoms, in certain types of heart failure, and during surgery to decrease bleeding. [3]
Typically, these constrictions are fully reversed by rapidly acting nitroglycerin. [ 4 ] [ 16 ] Individuals with variant angina may have many undocumented episodes of symptom-free coronary artery spasm that are associated with poor blood flow to portions of the heart and subsequent irregular and potentially serious heart arrhythmias .
Absolute contraindications are contraindications for which there are no reasonable circumstances for undertaking a course of action (that is, overriding the prohibition). For example: For example: Children and teenagers with viral infections should not be given aspirin because of the risk of Reye syndrome .
