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., particle size, powder density, powder flow and tabletability) Similar key parameters are calculated for common pharmaceutical excipients and stored in the apparatus. The apparatus then selects all relevant excipients and suggests a suitable manufacturing process. Combinations of active ingredients and excipients qualify as drug formulation if the predicted properties comply with the defined target profile. The following aspects can be considered: solubility and permeability of the active ingredient, dissolution of the active ingredient, probability to pass the content uniformity criteria, flowability of the powder blend, tabletability of the powder blend, mechanical strength and size of the tablet, compatibility of active ingredients and excipients etc.

Abstract: The present invention relates to a powder mixture for the preparation of a granulate comprising as constituent at least a filler or at least an active ingredient or both and as granulation aid Magnesium diacetate×4H2O and/or Magnesium dichloride×6H2O and/or Magnesium sulfate×7H2O and/or Disodium sulfate xH2O and/or Sodium thiosulfate×5H2O and/or Na3PO4×12H2O and/or Na2HPO4×12H2O/7H2O and/or Sodium acetate×3H2O. Optionally constituents of the powder mixture to be granulated are binders, disintegrants and further customary auxiliaries. It was an object of the present invention to provide a powder mixture which can be granulated without adding a liquid but where the water for the granulation is released in-situ from Magnesium diacetate×4H2O and/or Magnesium dichloride×6H2O and/or Magnesium sulfate×7H2O and/or Disodium sulfate xH2O and/or Sodium thiosulfate×5H2O and/or Na3PO4×12H2O and/or Na2HPO4×12H2O/7H2O and/or Sodium acetate×3H2O. An additional drying step is not required.
