The particle size of KCA-098 was remarkably reduced to a submicron size by grinding with HPC-SL. The co-ground mixture with HPC-SL showed a rapid dissolution rate and maintained supersaturation for more than 1 h. On the other hand, the co-ground mixture with PVP K30 showed rapid dissolution and supersaturation for a shorter period.
