Ketoprofen, (RS)2-(3-benzoylphenyl)-propionic acid (chemical formula C16H14O3) is one of the propionic acid class of non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic effects. It acts by inhibiting the body's production of prostaglandin.
Ketoprofen was available over-the-counter in the United States in the form of 12.5 mg coated tablets (Orudis KT & Actron), but the product has been discontinued. It is available by prescription as 25, 50, 75, 100, 150, and 200 mg capsules.
Brand names in the US are Orudis and Oruvail. It is available in the UK as Ketoflam and Oruvail, in Finland as Ketorin, in France as Bi-Profénid, in Italy as Fastum Gel or Ketoprofene, in Poland as Ketonal and Norway as Zon or Orudis.
In Lithuania, Ketoprofen is called Ketoprofenum and/or Ketoprofenas. For topical application: the name brands are Fastum with 2.5% (gel) which is over the counter and Ketospray with 10% (liquid spray) which must be prescribed. In Switzerland, and innovative ketoprofen formulation based on Transfersome® technology for direct application on the skin above the site to be treated has been approved.
In some countries, the optically pure (S)-enantiomer (dexketoprofen) is available; its trometamol salt is said to be particularly rapidly reabsorbed from the gastrointestinal tract, having a rapid onset of effects.
Ketoprofen is generally prescribed for arthritis-related inflammatory pains or severe toothaches that result in the inflammation of the gums.
Additionally, it should not be used in horses allergic to aspirin.
