For the selection of the optimal API, several solid forms may be available from one molecule. We provide an effective comparative programmethat will lead to a better orientation and targeted selection of the optimum solid form of a certain pharmaceutical molecule with requested properties.

• In vitrobioequivalence studies, which are less variable, easier to control, and can predict thein vivobioequivalence, saving time and cost

• Study of the dissolution rate profile of various forms

• Stability evaluation of various forms at different conditions of temperature and humidity

• Identification of the best physical form for pre-formulation
