Carprofen is a nonsteroidal anti-inflammatory drug (NSAID) of the carbazole and propionic acid class that was previously for use in humans and animals but is now only available to veterinarians for prescribing as a supportive treatment for various conditions in animals. Carprofen reduces inflammation by inhibition of PTGS1, COX-1 and Prostaglandin-endoperoxide synthase 2, COX-2; its specificity for COX-2 varies from species to species. Marketed under many brand names worldwide, carprofen is used as a treatment for inflammation and pain, including joint pain and postoperative pain. Human use Carprofen was used in humans for almost ten years, starting in 1988, for the same conditions as in dogs; namely, joint pain and inflammation. Side effects tended to be mild, usually consisting of nausea or Gastrointestinal disease, gastrointestinal pain and diarrhoea. It was available by Prescription drug, prescription in 150 Kilogram#SI multiples, mg to 600 mg doses. Dosages over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Racemic Mixture
In chemistry, a racemic mixture or racemate () is a mixture that has equal amounts (50:50) of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates. History The first known racemic mixture was racemic acid, which Louis Pasteur found to be a mixture of the two enantiomeric isomers of tartaric acid. He manually separated the crystals of a mixture, starting from an aqueous solution of the sodium ammonium salt of racemate tartaric acid. Pasteur benefited from the fact that ammonium tartrate salt gives enantiomeric crystals with distinct crystal forms (at 77 °F). Reasoning from the macroscopic scale down to the molecular, he reckoned that the molecules had to have non-superimposable mirror images. A sample with only a single enantiomer is an ''enantiomerically pure'' or ''enantiopure'' compound. Etymology The word ''racemic'' derives from Latin , meaning pertaining to a ...
