bismuth-tripotassium-dicitrate and Poisoning

Twenty-four urinary bismuth excretion was measured in five patients who had been treated with tripotassium dicitrato bismuthate, before and after single 1 g oral dose of D-penicillamine. Before dosing with D-penicillamine, the median 24 h urinary bismuth output was 55 micrograms 24 h-1 (range 17-156 micrograms 24 h-1) and following dosing with D-penicillamine the median 24 h urinary bismuth output was 53 micrograms 24 h-1 (range 12-156 micrograms 24 h-1). D-penicillamine does not facilitate the urinary excretion of bismuth, hence it is unsuitable for use as an oral chelator in patients with bismuth intoxication.
