(2) that the physical structure of the olanzapine particles is not altered over time, such as by conversion from an amorphous phase to crystalline phase; (3) that the olanzapine particles are chemically stable; and/or (4) where the olanzapine has not been subject to a heating step at or ...
Therefore, the development of strategies to induce the conversion of the crystalline into the (co-)amorphous form of drugs, and maintenance of such state, is of paramount importance. The conversion may be achieved directly during the manufacture of the dosage form, the so-called in situ ...
Introduction Active pharmaceutical ingredients (APIs) are exposed to water in many pharmaceutical processes, such as wet granulation or wet extrusion, which can lead to the conversion of the anhydrate form into the hydrate form during processing. The subsequent drying processes may induce the ...
