Patient-specific polypills, or similar drug products with potential to benefit from reduced need for bulking agent and preferably having multiple active ingredients, producible via appropriately adapted “micro-dosing” technologies not requiring fluid-jet or like substrate and solvent dependent approaches, having less need for excipient, particularly filler, so that the products may contain a larger number of different drug substances having a lower overall number or amount of excipient materials and/or may contain drug substances having comparatively less need for formulation development or pre-production processing and/or may contain fewer potential causes of side effects.
