Objective To prepare fenofibrate capsules using the nanosuspension technique for dissolution improvement and the bioavailability enhancement. Methods The fenofibrate nanosuspension was prepared using the method of anti-solvent precipitation technology and high pressure homogenization,then the dispersion was solidified by the method of spray drying to obtain fenofibrate capsules.The state of fenofibrate in nanosuspension was determined by using DSC and X-ray diffraction.The dissolution in vitro and bioavaila...
