title: Conversion in vitro of urinary (+)-penicillamine to its major metabolites, PSSP and PSSC.
abstract: To investigate the discrepancy between the apparent pharmacokinetic disposition of (+)-penicillamine in plasma and urine, the spontaneous degradation of (+)-penicillamine was studied in acidified and non-acidified urine. Degradation was prevented by acidification. The oxidized metabolites were converted to reduced (+)-penicillamine by electrolysis.
