For quick action in the treatment of angina, glyceryl trinitrate is used in form of a sublingual spray (nitro spray) or as soft capsules to be crunched. [4] Nitroprusside is used intravenously for the treatment of hypertensive crises, heart failure, and lowering of blood pressure during surgery. [5] [6]
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 ]
Three different forms of nitroglycerin: intravenous, sublingual spray, and the nitroglycerin patch. Nitroglycerin is used for the treatment of angina, acute myocardial infarction, severe hypertension, and acute coronary artery spasms. [1] [12] It may be administered intravenously, as a sublingual spray, or as a patch applied to the skin.
Nitroglycerin (NG) (alternative spelling 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.
The purpose of this mechanism to create NO is thought to be both sterilization of swallowed food (to prevent food poisoning) and to maintain gastric mucosal blood flow. [ 12 ] The nitrate-nitrite-nitric oxide pathway elevates nitric oxide through the sequential reduction of dietary nitrate derived from plant-based foods. [ 13 ]
Nicorandil activates K ATP channels in the mitochondria of the myocardium, which appears to relay the cardioprotective effects, although the mechanism is still unclear. [10] In experimental animal models of the Long QT syndrome , Nicorandil normalizes the prolonged cardiac action potential duration and the QT interval .
Its mechanism of action and clinical effects closely resemble those of nifedipine and the other dihydropyridine calcium channel blockers (amlodipine, felodipine), except that nicardipine is more selective for cerebral and coronary blood vessels. It is primarily a peripheral arterial vasodilator, thus unlike the nitrovasodilators (nitroglycerin ...
A drug class is a group of medications and other compounds that share similar chemical structures, act through the same mechanism of action (i.e., binding to the same biological target), have similar modes of action, and/or are used to treat similar diseases. [1] [2] The FDA has long worked to
