Abstract: OBJECTIVE To investigate the in vitro release and the pharmacokinetics in rabbits of the fluorofur implants.METHODS The implant,poly(2-hydroxyelthyl methacrylate)[poly(HEMA)]-collagen composite,made by fluorofur injection. RESULTS The release profiles in vitro conformed to Higuchi kinetics. The release index of the implant was t1/2=9.9h, t0.9=32.7h. The pharmacokinetic parameters in rabbits were:AUC=268.666h·μg/ml,MRT=41.704h,ka=0.334/h. CONCLUSION: The results clearly indicated that the poly(HEMA)-collagen hydrogel made by irradiation-induced polymerization offers excellent potential as a carrier for the sustained release implant of anticancer drugs.
