Pharmaceutical compositions of lurasidone
Solid dispersions of lurasidone or a pharmaceutically acceptable salt thereof are described, as well as pharmaceutical formulations thereof, and methods for making such formulations. 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., T max , C max , AUC 0-t and/or AUC 0-infinity ) of lurasidone, regardless of whether the pharmaceutical compositions are administered to a subject in the fed or fasted state.
1. A pharmaceutical composition comprising a solid dispersion of amorphous lurasidone or a pharmaceutically acceptable salt thereof,
wherein the solid dispersion consists of amorphous lurasidone or a pharmaceutically acceptable salt thereof, a pharmaceutically acceptable carrier, optionally a solubilizer, and optionally a surfactant;
wherein the pharmaceutically acceptable carrier is selected from the group consisting of hydroxypropyl methyl cellulose acetate succinate, a copolymer of polyvinyl pyrrolidone and vinyl acetate, hydroxypropyl cellulose, hydroxypropyl methylcellulose phthalate, and mixtures thereof;
wherein the solubilizer is selected from the group consisting of sorbitol, mannitol, polyvinyl alcohol, hydroxypropyl methylcellulose, hydroxypropyl cellulose, polyvinyl pyrrolidone, glycofurol and transcutol; and
wherein the surfactant is selected from the group consisting of anionic, nonionic, cationic, and zwitterionic surfactants;
further wherein the pharmaceutical composition is in the form of a tablet, and wherein the tablet comprises (a) granules of the solid dispersion of amorphous lurasidone or a pharmaceutically acceptable salt thereof, (b) at least one extra-granular excipient, and (c) optionally, a tablet coating;
wherein the at least one extra-granular excipient is selected from the group comprising microcrystalline cellulose, croscarmellose sodium, colloidal silicon dioxide, magnesium stearate, or mixtures thereof;
wherein said pharmaceutical composition upon oral administration in fasting and fed states exhibits bioequivalence to a reference drug product in the fed state;
wherein the reference drug product is a lurasidone drug product approved by the U.S. Food and Drug Administration in 2010 under New Drug Application Number 200603 and National Drug Code Number 63402-304; and
wherein the pharmaceutical composition may be administered without regard to food, and wherein said pharmaceutical composition comprises from about 25 mg to about 400 mg of lurasidone or pharmaceutically acceptable salt thereof.
2. The pharmaceutical composition according to claim 1 , wherein the solid dispersion of amorphous lurasidone has a weight ratio of the lurasidone or pharmaceutically acceptable salt thereof to the pharmaceutically acceptable carrier from about 1:2 to about 1:4.
3. The pharmaceutical composition according to claim 1 , wherein the solid dispersion of amorphous lurasidone has a weight ratio of the lurasidone or pharmaceutically acceptable salt thereof to the pharmaceutically acceptable carrier of about 1:3.
4. The pharmaceutical composition according to claim 1 , wherein the granules of the solid dispersion of amorphous lurasidone comprise at least a first portion of granules comprising lurasidone and hydroxypropyl methyl cellulose acetate succinate, and optionally, a second portion of granules comprising lurasidone and a copolymer of polyvinyl pyrrolidone and vinyl acetate.
5. The pharmaceutical composition according to claim 1 , wherein the tablet is obtained by direct compression, wet granulation or dry granulation.
6. The pharmaceutical composition according to claim 1 , further comprising at least one excipient selected from the group consisting of binders, disintegrating agents, lubricants, colorants, and mixtures thereof.
7. The pharmaceutical composition according to claim 1 , wherein the granules of the solid dispersion of amorphous lurasidone comprise hydroxypropyl methyl cellulose acetate succinate as the pharmaceutically acceptable carrier; hydroxypropyl cellulose as the solubilizer, and optionally sodium lauryl sulfate as the surfactant.
