| 摘 要： | 目的利用固体分散技术提高坎地沙坦的溶解性。方法以体外溶出度为指标，通过单因素试验，考察处方和工艺因素对坎地沙坦固体分散体中药物溶出的影响，运用正交试验选定坎地沙坦固体分散体的最优处方；采用FTIR、DSC、XRD分析技术对药物与载体间的相互作用及药物在固体分散体中的存在状态进行鉴定，探讨固体分散体的增溶机制，考察固体分散体的稳定性。结果以聚乙烯吡咯烷酮（PVPK30）为载体，二氯甲烷：甲醇：乙醇－2：2：l为混合溶剂制备的固体分散体溶出度lh可达99％；红外分析表明坎地沙坦与PVPK30间有氢键形成；DSC及XRD表征表明坎地沙坦以微晶或无定形态分散于PVPK30中；稳定性加速试验显示固体分散体经过30d后XRD显示药物无明显的团聚，仍以微晶或无定形态存在。结论固体分散技术能有效提高坎地沙坦的溶出度。制得的坎地沙坦固体分散体为一稳定体系，具有实际应用价值。
