Abstract
- An inclusion complex of praziquantel with 2-hydroxypropyl-β-cyclodextrin was designed and prepared by an optimized method and the inclusion complex was characterized by infrared absorption spectral, proton NMR spectral and scanning electron image studies. It was shown that the aqueous solubility of praziquantel has increased (~104 fold) in comparison with praziquantel alone, which is the best result so far for praziquantel solubility study. The in vivo pharmacokinetic properties of praziquantel in dogs such as C max , T max , AUC 0 -∞, and t 1/2 have been improved significantly after complexation. The increased water solubility of the praziquantel in the complex resulted in the improved values of C max (4.82 μg/mL vs 0.51 μg/mL, 9.45 fold higher) and AUC 0 -∞ (98.06 μg h/mL vs 20.63 μg h/mL, 4.75 fold higher) in dog pharmacokinetic studies, which is useful to find a new praziquantel formulation as an anti-schistosomal agent.
