    Abstract:
    Quantitative Determination of the Main Metabolites of Acetylsalicylic Acid / 2nd Communication: The concentrations of salicylic acid and its metabolies in patients with renal insufficiency 9 patients suffering from renal insufficiencies of varing degrees and treated regularly by hemodialysis were given 1.5 g Colfarit (microcapsulated acetyl salicylic acid) as a single dose. The concentrations of salicylic acid (SA), salicyluric acid (SU), further salicylic acid conjugates (SAC) and salicyluric acid conjugates (SUC) were determined in the blood plasma. Likewise urea and creatinine were determined. SA concentration decreased continually and, at the end of the trial (72 h after application), had vanished almost completely from the plasma of most patients. SU increased at first and decreased afterwards. With the exception of the dailysis time SAC and SUC increased during the trial. After 3 days the SUC level was more than 50% of total salicylate (SSS) in most patients. SSS (the sum of SA + SU + SAC + SUC) did not change very much before dialysis, but showed a rather high decrease during the first hours of dialysis. tafter dialysis the SSS levels rose again, apparently as a consequence of a redistribution and of the synthesis of conjugates with decreased tissue affinity. It could be shown that SSS in the blood plasma does not parallel SSS in the whole body. The interindividual variation of SA metabolism as well as the variation of the biological blank values was rather high. The results are discussed with regard to salicylate pharmacokinetics in renal insufficiency and to normal salicylate metabolism.
