Ethoxycarbonyloxy ethyl esters of non-steroidal anti-inflammatory carboxylic acids, their preparation and use.

摘要

The invention provides esters of the general formula <CHEM> in which R-@- is the acyl residue of a non-steroidal anti-inflammatory compound containing a carboxylic acid function. The esters may be prepared by reacting an acid R-COOH, when R is as above, with a 1-haloethyl ethyl carbonate. The esters may be formulated to provide pharmaceutically or veterinarily acceptable formulations.
