The pre-formula study and screening of formula and preparation process were done to prepare capreomycin sulfate liposome. By adding proper cryoprotectant and selecting appropriate process, liposome bearing freeze-drying procedure and we got dry powder of liposome finally. The object of this paper was to prepare capreomycin sulfate liposome with high drug-lipid ratio, high encapsulation efficiency and good stability, so as to reach lung targeting and lower toxicity.
The in vitro analyzing method of capre...
