采用乳化溶剂挥发的方法制备MeOCPT纳米粒子,结果表明:MeOCPT纳米粒子具有明显的圆形结构,且表面光滑,大小均匀,粒度分布在100~300 nm之间。MeOCPT的载药量和包封率分别为(3.10±1.19)%和(83.57±3.45)%,在体外可以持续缓慢释放,累积释放率接近60%,达到了预期的药物缓慢释放及降低毒性的结果。

채용유화용제휘발적방법제비MeOCPT납미입자,결과표명:MeOCPT납미입자구유명현적원형결구,차표면광활,대소균균,립도분포재100~300 nm지간。MeOCPT적재약량화포봉솔분별위(3.10±1.19)%화(83.57±3.45)%,재체외가이지속완만석방,루적석방솔접근60%,체도료예기적약물완만석방급강저독성적결과。
The nanoparticles contained MeOCPT prepared with the method emulsion and solvent evaporation.The MeOCPT nanoparticles had a circular structure,with a smooth surface,uniform size,and its particle size distributed between 100 nm and 300 nm.The drug-loading rate and entrapment efficiency of MeOCPT nanoparticles were(3.10±1.19)%and(83.57±3.45)%.MeOCPT nanoparticles released slowly and lastingly in vitro whose cumulative release rate was nearly 60%,which could release the drugs slowly and reduce the toxicity of drugs.
