| Abstract: | OBJECTIVE： To prepare paclitaxel liposome and study its quality. METHODS： Paclitaxel liposome was prepared by film dispersion method, and the content of paclitaxel was determined by HPLC. The encapsulation efficiency （EE） and the in vitro release rate of liposome were computed as well. RESULTS： The particle size of the prepared liposome ranged from 70 mn to 150 nm and its EE% was 96.46%. The linear range of paclitaxel was 0.3-75 ug · mL ^-1（r=0.999 8） with an average recovery rate of 100.3% （RSD = 1.16%, n = 3） . The release rate of paclitaxel liposome in vitro fitted to Higuchi model and was characterized by slow release. CONCLUSIONI The film dispersion method is suitable for the preparation of paelitaxel liposome. This drug has a slow release property in vitro. |
