[Abstract]
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.
