title: Analysis of sulindac and metabolites in plasma and urine by high-performance liquid chromatography.
abstract: A reversed-phase high-performance liquid chromatographic method with ultraviolet detection is described for the quantification of sulindac, sulindac sulfone and sulindac sulfide in plasma and sulindac, trans-sulindac, sulindac sulfone and sulindac sulfide in urine. Plasma samples are de-proteinized with acetonitrile and urine samples are injected directly following enzymatic hydrolysis of glucuronide metabolites. The resulting chromatograms are essentially free from endogenous interference and the limits of detection are 0.1 microgram/ml for plasma and 0.2 microgram/ml for urine for all of the above compounds.
