Stover Urinary metabolites were extracted with ethyl acetate and purified using high performance liquid chromatography (HPLC).2 The eluate was incubated with the diazo reagent and three positive fractions were found.2 The retention times of the two metabolites in HPLC were equivalent to those of the 6- and 7-hydroxylated metabolites of etodolac (6- and 7-OH-etodolac).2 Authentic compounds of the 6- and 7-hydroxylated metabolites also gave a positive reaction in the diazo methods.2 These results indicate that 6- and 7-OH-etodolac are mainly responsible for the false positive reactions of the urine sample from patients treated with etodolac. We experienced this briefly during the initial week after discontinuing the Ictotest confirmation procedure. Unauthorized use of these marks is strictly prohibited.
