In one aspect, the processes comprise the steps of (1) compressing a pre-tabletting material in a die to form a tablet, where an internal surface of the die is lubricated with at least one lubricant, and the pre-tabletting material comprises at least one therapeutic agent and at least one pharmaceutically acceptable polymer; and (2) ejecting said tablet from said die. In another aspect, the processes employ a granular or powdery pre-tabletting material which comprises at least one therapeutic agent and at least one pharmaceutically acceptable polymer, wherein 90% of the particles in the pre-tabletting material are smaller than 400 [mu]m. |
