目的 制備長春瑞濱磷脂復合物,提高藥物的脂溶性,以期進一步制備長春瑞濱微粒載藥系統(tǒng)。方法 采用溶劑揮發(fā)法制備長春瑞濱磷脂復合物,以復合率為評價指標進行單因素優(yōu)化試驗。采用差示掃描量熱法、X射線衍射法、紫外分光光度法對復合物進行鑒別,并考察復合物的體外溶解性質變化。結果 優(yōu)化條件下制備的磷脂復合物復合率為89.3%~93.7%;差示掃描量熱法、X射線衍射法、紫外分光光度法驗證了復合物的形成;形成磷脂復合物后,長春瑞濱的脂溶性顯著提高。結論 制備的長春瑞濱磷脂復合物能顯著增加藥物的脂溶性,為進一步制備長春瑞濱微粒載藥系統(tǒng)奠定基礎。

Objective To prepare vinorelbine-phospholipid complex (VPC) for enhancing the liposolubility of vinorelbine. Methods The complex was prepared using solvent evaporation method. The preparation technology was optimized by single factor design, using the combining ratio as the assessment index. Differential scanning calorimetry (DSC), X-ray diffraction (XRD) spectrum, and UV spectrophotometry were carried out to investigate its characterization. The in vitro solubility change of the complex was also determined. Results The combining ratio of the complex prepared under the optimized conditions was between 89.3% and 93.7%; UV spectrum, DSC and XRD spectra confirmed the formation of the complex. After phospholipid complex being made, the liposolubility of vinorelbine was remarkably enhanced. Conclusions Prepared vinorelbine-phospholipid complex could effectively enhance the liposolubility of vinorelbine and provide the reference for preparation of vinorelbine microsomal drug-loaded system.
