abstract：:There is a trend towards increasing doses of pralidoxime to treat human organophosphate poisonings that may have relevance in subpopulations. Indeed, pralidoxime is eliminated unchanged by the renal route. This study assesses the effect of renal failure on the kinetics of pralidoxime in a rat model of acute renal fail...
