Sodium salicylate is a sodium salt of salicylic acid. It can be prepared from sodium phenolate and carbon dioxide under higher temperature and pressure. Historically, it has been synthesized by refluxing methyl salicylate ( wintergreen oil) with an excess of sodium hydroxide .
Sodium salicylate is a useful phosphor in the vacuum ultraviolet spectral range, with nearly flat quantum efficiency for wavelengths between 10 and 100 nm. [22] It fluoresces in the blue at 420 nm. It is easily prepared on a clean surface by spraying a saturated solution of the salt in methanol followed by evaporation.
Aspirin is also used long-term to help prevent further heart attacks, ischaemic strokes, and blood clots in people at high risk. [10] For pain or fever, effects typically begin within 30 minutes. [10] Aspirin works similarly to other NSAIDs but also suppresses the normal functioning of platelets. [10] One common adverse effect is an upset ...
History of aspirin. Aspirin (acetylsalicylic acid), an organic compound that does not occur in nature, was first synthesised in 1899. In 1897, scientists at the drug and dye firm Bayer began investigating acetylated organic compounds as possible new medicines, following the success of acetanilide ten years earlier.
Salicylate poisoning. A skeletal structural formula for aspirin. Salicylate poisoning, also known as aspirin poisoning, is the acute or chronic poisoning with a salicylate such as aspirin. [1] The classic symptoms are ringing in the ears, nausea, abdominal pain, and a fast breathing rate. [1]
Salicylate intolerance is a form of food intolerance or of drug intolerance. Salicylate sensitivity is a pharmacological reaction, not a true IgE -mediated allergy. However, it is possible for aspirin to trigger non-allergic hypersensitivity reactions. [8][9] About 5–10% of asthmatics have aspirin hypersensitivity, but dietary salicylates ...
Salicylates, including aspirin (acetylsalicylic acid), magnesium salicylate, and sodium salicylate. These are also primarily nonselective COX inhibitors, but also work through other mechanisms including activating AMP-activated protein kinase. [9] COX inhibitors that are relatively selective for the COX-1 enzyme, such as ketoprofen and ...
Additionally, aspirin induces the formation of NO-radicals in the body, which have been shown in mice to have an independent mechanism of reducing inflammation. This reduces leukocyte adhesion, which is an important step in immune response to infection. There is currently insufficient evidence to show that aspirin helps to fight infection. [17]
