[80] NSAIDs are of unclear utility in the prevention and treatment of Alzheimer's disease. Research indicates that ibuprofen a drug used to relieve inflammation and pain is a mixture of two enantiomers; that is molecules that A) have identical chemical formulas but differ in the branching of their carbon skeletons. Ibuprofen reacts with base to form salt and water. The analgesic, antipyretic, and anti-inflammatory activity of NSAIDs appears to operate mainly through inhibition of COX-2, which decreases the synthesis of prostaglandins involved in mediating inflammation, pain, fever, and swelling. Cyclooxygenase 1 is responsible for the synthesis of prostaglandins. aromatic group or Benzene ring in the centre of the structure. groups. The Aspirin is also a carboxylic acid ( CO 2 H) and an ester ( CO 2 CH 3 ). [58], The isomerase enzyme, alpha-methylacyl-CoA racemase, converts (R)-ibuprofen into the (S)-enantiomer. It has nonnarcotic, analgesic, and antipyretic effects. normal alkane (single carbon-hydrogen bonds) groups. The first is the The ibuprofen: carboxylic acid / carboxyl. An incredible 20,000 tonnes of ibuprofen are now made every year by a range of different companies under many different brand names. [21], Ibuprofen lysine is sold for rapid pain relief;[22] given in form of a lysine salt, absorption is much quicker (35 minutes compared to 90120 minutes). Functional Groups A functional group is an atom or a group of atoms within a molecule that have characteristic physical properties and are often the sites of chemical reactivity. [13][14], Ibuprofen is used primarily to treat fever (including postvaccination fever), mild to moderate pain (including pain relief after surgery), painful menstruation, osteoarthritis, dental pain, headaches, and pain from kidney stones. Experts are tested by Chegg as specialists in their subject area. and a carboxylic acid functional group.
