NCIt definition : The sodium salt form of flurbiprofen, a propionic acid derivative and a member of
the phenylalkanoic acid group of non-steroidal antiinflammatory drugs (NSAIDs) with
analgesic, antiinflammatory and antipyretic effects. Flurbiprofen non-selectively
binds to and inhibits cyclooxygenase (COX). This results in a reduction of arachidonic
acid conversion into prostaglandins that are involved in the regulation of pain, inflammation
and fever. This NSAID also inhibits carbonic anhydrase, thereby reducing the production
of hydrogen and bicarbonate ions. Upon ocular administration, flurbiprofen may reduce
bicarbonate ion concentrations leading to a decrease in the production of aqueous
humor, thereby lowering intraocular pressure.;
