Effects of the non‐steroidal anti‐inflammatory drug benoxaprofen on leucocyte migration

Possible modes of action of the anti-inflammatory drug, benoxaprofen, have been explored. The drug caused inhibition of leucocyte migration, principally of mononuclear cells into the pleural cavity of rats undergoing carrageenan-induced pleurisy. Evidence was obtained from in vitro leucocyte migration and chemotaxis models that the drug acted directly on the mononuclear cells rather than by inhibition of chemotactic factors.
