ABSTRACT
Objective To detect the in-vitro recovery of tetramethylpyrazine phosphate (TMPP) in microdialysis probe and to study its stability. Methods The recovery of TMPP was detected by concentration difference method (increment method and decrement method ). The effect of flow rates and concentrations on recovery was studied. Results The recovery detected by increment method was as the same as that detected by decrement method; TMPP recovery was independent of TMPP concentration in the external medium. TMPP recovery had good stability. Conclusion Microdialysis sampling can be used for the pharmacokinetic study of TMPP and decrement method (ie. retrodialysis) can be used for the determination of TMPP recovery.
