摘要：

Phase-solubility studies have been used to evaluate the solubilizing effects of cyclodextrins (CDs) on lipophilic, water-insoluble drugs. However, large amounts of CDs and drugs are required to measure solubility by phase-solubility studies. Thus, more efficient approaches to evaluate the interaction of CDs with drugs are needed. Herein we introduce a method that evaluates the interaction between immobilized beta-cyclodextrin and psychotropic drugs by surface plasmon resonance assay with a Biacore (R) system. Association constants and stoichiometries observed were generally consistent with values calculated by traditional methods, such as phase-solubility and continuous variation methods. Results showed that the analytical method using Biacore (R) was suitable to evaluate CD-drug interactions. (c) 2010 Elsevier B.V. All rights reserved.
