Preferably, the solid dispersions are prepared by hot-melt extrusion or spray-drying, and comprise lurasidone with a pharmaceutically acceptable carrier (e.g., hydroxypropyl methyl cellulose acetate succinate (HPMC-AS), polyvinyl pyrrolidine vinyl acetate (PVP/VA) copolymer, hydroxypropyl methylcellulose phthalate (HPMCP), or mixtures thereof). The pharmaceutical composition may be orally administered to a patient in either the fed or fasted state, with a decrease or elimination of the food effect. Preferably, following oral administration of the pharmaceutical compositions, there is no substantial difference in the pharmacokinetic parameters (e.g., Tmax, Cmax, AUC0-t and/or AUC0-infinity) of lurasidone, regardless of whether the pharmaceutical compositions are administered to a subject in the fed or fasted state.
