Abstract
SUMMARY. The solubility enhancement ability of different methods was compared by using dexibuprofen (DEX) as a model drug. Binary inclusion complexes of DEX were prepared with beta cyclodextrin (βCD) at weight ratio of 1:1,1:2 and 1:4 by physical trituration (PT), kneading (KN) and solvent evaporation (SE) method. The phase solubility studies illustrated that DEX solubility increased proportionally with an increase in βCD concentration. The solubility of DEX was significantly higher when complexed with βCD by KN method. DEX-βCD complexes were examined critically by using infrared (FTIR), differential scanning calorimetry (DSC), powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). FTIR and XRD did not show any significant difference between DEX-βCD complexes prepared by PT and KN method. DSC thermograms of DEX-βCD prepared by KN method were showed a decrease in the intensity of endothermic peak of DEX more than PT method. XRD results indicated that DEX shifted to less crystalline state when complexed with βCD. In conclusion, βCD is suitable to increase the solubility of DEX.
