HPLC monitoring of pharmacokinetics was done in two body compartments of rats following intramuscular treatments with three different doses of K027, a bispyridinium mono-aldoxime type of antidotes to organoposphate intoxicated subjects. Reversed-phase HPLC separation with electrochemical detections was done to monitor the onset, the maximum level, and offset in K027 concentration. Serum level of K027 showed a fast onset, independently from the doses of K027. Drug level in brain was showing an essentially delayed kinetics.
