ABSTRACT
OBJECTIVE:
To investigate release characteristics of sirolimus liposome in vitro.METHODS:
The concentration of sirolimus was determined by RP-HPLC.In vitro release rate of sirolimus liposome within 24 h was investigated by the reverse dialysis method with 20% ethanol 500 mL as medium.Release curve of sirolimus was fitted with drug release model equation.RESULTS:
The linear range of sirolimus were 0.5~20 ?g.mL-1(r=0.999 8)with an average recovery of 99.42%(RSD=1.23%).At the first 4 hours of release,sirolimus liposome released rapidly with accumulative release rate of 50%.After that release rate of liposome was slowed down with accumulative rate of 80% in 24 h.The in vitro release curve conformed to the first order equation.CONCLUSION:
Sirolimus liposome has delayed release capability,and in vitro drug release of sirolimus liposome is in concentration dependant manner.
