Polymeric micelles have been widely used to increase the solubility of some water-insoluble drugs in recent years. Cyclosporine A (CyA), a water-insoluble peptide, was chosen as the model drug for the study of solubilization capacity of polymeric micelles. The freeze-drying technology, in vitro release behavior and stability of CyA-loaded mPEG-PLGA polymeric micelles were also investigated. Pharmacokinetic behaviors of polymeric micelles in rats were studied compared with Sandimmune, a commonly used...
