本发明公开了一种维立西呱自微乳组合物及其制备方法和应用。该组合物包含维立西呱0.2%‑1.2%(w/w)、油相3%‑20%(w/w)、表面活性剂20%‑40%(w/w)、助表面活性剂45%‑75%(w/w)、沉淀抑制剂。所述油相选自MCT、MCM、GMO或其混合物;所述表面活性剂选自RH40、Labrasol、Transcutol HP或其组合;所述助表面活性剂选自PEG400、丙二醇、甘油或其混合物;所述沉淀抑制剂选自选自聚乙烯己内酰胺‑聚醋酸乙烯酯‑聚乙二醇接枝共聚物(Soluplus)、泊洛沙姆188、聚乙烯吡咯烷酮(PVP)或其混合物。该组合物可在胃肠道内自发形成微乳,有望提高维立西呱在空腹状态下的生物利用度,改善食物效应,减少个体间变异,提高患者用药依从性。
