Abstract
Objective To prepare liposomal in-situ gel (ISG) for ear with sparfloxacin (SF) as the modeldrug,and investigate the drug release in vitro. Methods SF liposomes (SFL) were prepared by the film dispersion method. Poloxamer 407 was used as themosensitive material for the SFL-ISG. A membraneless model was used to study in vitro release of the drug and compared with that of ISG containing SF only( SFISG). Result SFL in SFL-ISG was uniformly distributed with mean size of(836.8 + 54.5) nm. The properties of the drug release in vitro and gel corrosion were in consistence with zero-order kinetics with the equation of y = 3. 0870x - 5. 2581 ( r = 0.997 8 ) and y = 0. 2299x + 1. 6892 ( r = 0. 997 3 ), respectively.Conclusion SFL-ISG can be prepared easily with suitable gelation temperature, and it may delay the drug release, which is valuable to study further.关键词
