ABSTRACT
The study is to investigate the brain pharmacokinetics change of nasal tetramethylpyrazine phosphate (TMPP) pH-sensitive in situ gel in normal and model rats. Acute cerebral ischemia rat model was successfully established by middle cerebral artery occlusion (MCAO) method. Both normal and model rats were given nasal TMPP pH-sensitive in situ gel (10 mg x kg(-1)). Perfusates of brain striatum area were collected at each time point by microdialysis. The content of TMPP was determined by HPLC. The pharmacokinetics parameters were calculated by Kinetica 4.4 software at each time point of the brain drug concentration. The main pharmacokinetics parameters of TMPP were fitted with compartments 2. After nasal TMPP pH-sensitive in situ gel the values of C(max) and AUC of both components in brain showed as follows the value of model group > that of normal group. Significant difference can be observed in the process of brain pharmacokinetics in normal and model rats after giving nasal TMPP pH-sensitive in situ gel.
