Abstract : Pralidoxime chloride, used clinically to reactive cholinesterase in organophosphate poisoning, is rapidly eliminated by the kidney. In these studies, heat and exercise stress significantly decreased the renal excretion of both pralidoxime and p-aminohippurate (PAH, used to estimate renal plasma flow) in man. Pharmacokinetic data suggest that overall drug removal from plasma is also affected by changes in tissue distribution of these drugs: with stress conditions there is a marked increase in volumes of drug distribution. Furthermore, decreased total recovery of drugs in the urine under heat and exercise conditions implicates tissue metabolism as a factor of heretofore undetermined significance in the overall elimination of both pralidoxime and PAH.
