Abstract
An amorphous solid dispersion (ASD) of sorafenib (SOR) in hydroxypropyl methylcellulose acetate succinate (HPMC-AS), prepared by coprecipitation, was used to develop an immediate release tablet with improved oral bioavailability. An ASD of 40% drug loading with HPMC-AS (M grade), which exhibited superior physical stability and enhanced dissolution, was selected for tablet development. Systematic characterization of powder properties of the ASD led to the choice of the dry granulation process to overcome poor flowability of the ASD. The designed tablet formulation was evaluated using a material-sparing and expedited approach to optimize compaction conditions for manufacturing ASD tablets with low friability and rapid disintegration. The resulting SOR ASD tablets exhibited approximately 50% higher relative bioavailability in dogs than the marketed SOR tablet product, Nexavar®.
