Cloximate is a non-steroidal anti-inflammatory drug, developed in the Dutch company Philips-Duphar B.V. Research Laboratories in the 1970s. Cloximate acts by inhibition of PGE2 biosynthesis. In preclinical experiments, cloximate showed good inhibitory activities in local exudative tests, in the proliferative and functional aspects of experimental inflammation, as well as in the bradykinin-evoked bronchoconstriction test. Cloximate showed almost no harmful effects on the gastrointestinal mucosa and no influence upon the emptying rate of the stomach. Cloximate was evaluated in double-blind clinical trials, where different formulations were compared with naproxen. Gastrointestinal blood loss increased more in the naproxen group than in the group treated with non-enteric coated cloximate.
