Abstract:
Objective To study target-distribution of flurbiprofen axetil in operative incision tissue in incision-induced rats. Methods Thirty-two-250 g-weight rats were randomly divided into 4 groups. The incision pain model was established by being operated according to Brennan's method. Two hours after vena caudalis injection, all the rats were anesthetized deeply by pentobarbital sodium-perito injection 100 mg/kg,muscles of both hind paws were dissected, homogenated, centrifuged and supernatant fluids were dissociate. The concentration of flurbiprofen were detected by reversed phase high peformance liquid chromatography(RP-HPLC). Results In these groups of different dosage, the concentration of flurbiprofen in operative incision notably increased compared to that in the non-operative incision, especially in group K16. The concentration of flurbiprofen in operative incision of different dosage increased in dose-dependent manner. The difference of concentration of flurbiprofen in non-operative incisions of K2, K4, K8 was statistically insignificant, but the concentration of flurbiprofen in non-operative incision of K6 increased compared to that of K2, K4 and K8. Conclusion The distribution of flurbiprofen axeti in operative incision was targeted. When rats were injected flurbiprofen axetil at 16 mg/kg by vena caudalis, The concentration of flurbiprofen in the non-operative incision increased notably.
