ABSTRACT
OBJECTIVE:
To prepare the gene recombined human interferon-alpha poly(lactic acid-co-glycolic)microspheres and study its physicochemical properties.METHODS:
Interferon-? microspheres were prepared by W/O/W solvent extraction technique;the in vitro release of microspheres were examined;the rudimental organic solvent was determined with GC-MS.RESULTS:
The IFN-?-MS were regular in their morphology,and the particle size distribution was narrow.The average diameter was 45.54?m.The encapsulation rate and the loading efficiency were 83.49% and 8.03%,and the in vitro accumulative release rate was 80.32% in 30 days.The in vitro interferon-? release from the microspheres was best described using Higuchi diffusion model.The rudimental of dichloromethane was less than 0.05%.CONCLUSIONS:
The prepared IFN-?-MS is very good in all aspects of its physicochemical properties.
