摘要
Naproxen is a poorly soluble anti-inflammatory drug, the solubility of which can be enhanced by complexation with betacyclodextrin. Besides that, the inclusion complex reduces the incidence of gastrointestinal side effects of the drug. The aim of this work was to compare the physicochemical characteristics of the solid complexes prepared by traditional methods (kneading, freeze-drying and spray-drying) and using a supercritical fluid technology. The unusual solvent properties of carbon dioxide above their critical temperature and pressure were exploited in order to prepare inclusion compounds. Complexes prepared using supercritical fluid technology showed similar properties to those of freeze-drying and spray-drying complexes as proved by DSC, FT-IR and UV.
