Abstract
An HPLC assay for sulphapyridine is described. The use of the assay to measure sulphapyridine produced by the action of large bowel flora on 2 g of orally administered sulphasalazine as a means of assessing oro-colonic transit time is discussed. The assay is applied to show the action on oro-colonic transit time of a novel gastrokinetic agent BRL 24924 which brought about a 62.8% median reduction in transit time at a dose of 5 mg.
