The objective of this study was to evaluate the influence of oxatomide β-cyclodextrin inclusion complex on the physicochemical properties and bioavailability of the drug. Oxatomide β-cyclodextrin solid complex was prepared with equimolar ratio of both oxatomide and β-cyclodextrin in presence or absence of water soluble polymers using different techniques. The co-evaporated complex prepared in presence of PVP-K15 showed a prompt drug release and significantly increased % dissolution efficiency (P < 0.05) compared to the pure oxatomide. Moreover, the results of bioavailability evaluation of this complex in rabbits compared to commercial drug product indicated that 73.15 % increase in the oral bioavailability of oxatomide. In conclusion, inclusion complex of oxatomide with β-cyclodextrin prepared by co-evaporation in presence of PVP-K15 results not only in an enhancement of the oxatomide dissolution rate but also improves the bioavailability of oxatomide.
