Abstract: In order to facilitate product development, such as pharmaceutical product development, a computer implemented method and an apparatus are proposed that enable formulators to develop robust drug formulations in a cost- and time-efficient manner. To start the development process, the user selects the preferred dosage form (e.g., granules, pellets, capsules, tablets etc.), defines a target profile (e.g., amount of active ingredient per unit, size of dosage form, mechanical strength of dosage form, desired release behaviour etc.) and enters key characteristics of the active ingredient (e.g., true density, particle size distribution data, bulk and tapped density, angle of repose, compressibility and compactibility profile etc.). The identity (e.g., chemical name or structure) of the active ingredient is not necessarily disclosed. The apparatus processes the provided data and calculates key parameters of the AI (e.g.
