Abstract: A system and a method for a constant micro dosing of powder material include a control device, a cylinder with a first opening and a piston movably arranged inside the cylinder and controllable by the control device. The piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder stores the powder material between the piston and the first opening. The piston pushes the powder material through the first opening by moving along the piston stroke direction. Further the system and the method include a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device controls the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.

Abstract: A method of monitoring a property of a dissolution of an at least partially solid dosage form during a dissolution process is disclosed. The method includes at least partially dissolving the dosage form, and during the dissolution of the dosage form, simultaneously monitoring the property of the dissolution of the dosage form in progress by low coherence interferometry.

Abstract: An apparatus for manufacturing a medication comprising an ejector unit adapted for ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. The ejector unit comprises a capillary and a tubular piezoelectric actuator surrounding at least a part of the capillary. The apparatus further comprises a control unit adapted for applying an electric signal to the piezoelectric actuator which, in response to the electric signal, is adapted to generate a compressional wave in the capillary for ejecting the predefined amount of the drug via an orifice of the capillary. Moreover, a method of manufacturing a medication is provided, the method comprising ejecting a predefined amount of a drug having a liquid component to a solid carrier substrate. Furthermore, a medication is provided comprising a solid carrier substrate, and a predefined amount of a drug ejected with a liquid component to the solid carrier substrate by an ejector unit.
