摘要
The preparation of an inclusion complex of Lorazepam, a benzodiazepine antianxiety agent with beta -cyclodextrin is described. The inclusion compound was prepared by the homogeneous coprecipitation method in the molar ratio of 1:2 of the drug and beta -cyclodextrin respectively. The formation of inclusion complex was evaluated by UV spectral studies, IR studies, X-ray diffractometry, and Differential Thermal Analysis. The solubility and in-vitro drug release studies indicated that the complex form of the drug significantly increase the solubility and the dissolution rate compared to the free form. Tablets prepared with Lorazepam- beta -cyclodextrin complex also showed a significant increase in dissolution of the drug indicating that beta -cyclodextrin plays an important role in the solubilization of the drug.
