carboxylic acids

A group of non-steroidal anti-inflammatory and ANALGESIC drugs that includes aspirin, aloxiprin, mefenamic acid, fenbufen and ibuprofen.

carboxylic acids

organic acids containing one or more carboxyl [COOH] groups, for example monocarboxylic acids with one carboxyl group, DICARBOXYLIC ACIDS with two carboxyl groups, TRICARBOXYLIC ACIDS with three carboxyl groups. See also FATTY ACIDS.
