title: Relationship between the inhibitory activity on 'RCS' and prostaglandins synthesis and the anti-inflammatory activity of ketoprofen and several other non-steroidal anti-inflammatory agents.
abstract: In this study ketoprofen has been shown to be the most potent of all anti-inflammatory drugs in inhibiting the synthesis of prostaglandins and the 'rabbit-aorta contracting substance' (RCS), using the guinea-pig lung preparation. Although there did not appear to be a close relationship between the activities of the various drugs in inhibiting prostaglandins synthesis and in their anti-inflammatory activity, the compounds were ranked in the same order in both test systems.
