Abstract: Objective To investigate synthesis of medium substituted degree hydroxypropyl-β-cyclodextrins and the complex forming capability of dexamethasone. Methods Medium substituted degree hydroxypropyl-β-cyclodextrins were prepared and tested by pharmacopoeia.Dexamethasone were included with the product and performed by the phase-solubility diagram. Results The substituted degree of hydroxypropyl-β-cyclodextrins were 7.875.Dexamethasone was formed a 11 molar ratio inclusion complex with the product and improved solubility about 33 times. Conclusion The product accord with the request of pharmacopoeia.The dissolution capability of dexamethasone was increased by hydroxypropyl-β-cyclodextrins.
