Phenobarbital is one of the first-line drugs of choice to treat epilepsy in dogs, as well as cats. [11] It is also used to treat feline hyperesthesia syndrome in cats when anti-obsessional therapies prove ineffective. [72] It may also be used to treat seizures in horses when benzodiazepine treatment has failed or is contraindicated. [73]
Phenol spray, with phenol as the active ingredient, is used medically to treat sore throat. [38] It is the active ingredient in some oral analgesics. [38] Concentrated phenol liquids are used for permanent treatment of ingrown toe and finger nails, a procedure known as a chemical matrixectomy. The procedure was first described by Otto Boll in 1945.
Pills are thought to date back to around 1500 BC. [1] Earlier medical recipes, such as those from 4000 BC, were for liquid preparations rather than solids. [ 1 ] The first references to pills were found on papyruses in ancient Egypt and contained bread dough, honey, or grease.
Phenol is readily alkylated at the ortho positions using alkenes in the presence of a Lewis acid such as aluminium phenoxide: [citation needed] CH 2 =CR 2 + C 6 H 5 OH → R 2 CHCH 2 -2-C 6 H 4 OH More than 100,000 tons of tert-butyl phenols are produced annually (year: 2000) in this way, using isobutylene (CH 2 =CMe 2 ) as the alkylating agent.
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C 6 H 4 (OH) 2. It has two hydroxyl groups bonded to a benzene ring in a para position.
The salicylic acid is absorbed and therapeutical concentrations of salicylic acid can be found in blood after bismuth subsalicylate administration. Bismuth oxychloride and bismuth hydroxide are both believed to have bactericidal effects, as is salicylic acid for enterotoxigenic E. coli, a common cause of "traveler's diarrhea". [5]
Naproxen's medical uses are related to its mechanism of action as an anti-inflammatory compound. [11] Naproxen is used to treat a variety of inflammatory conditions and symptoms that are due to excessive inflammation, such as pain and fever (naproxen has fever-reducing, or antipyretic, properties in addition to its anti-inflammatory activity). [11]
[1]: 41–42 The public pressure soon forced Schweitzer and Edison to end the phenol deal—with the embarrassed Edison subsequently sending his excess phenol to the U.S. military—but by that time the deal had netted the plotters over two million dollars and there was already enough phenol to keep Bayer's Aspirin plant running. Bayer's ...
