摘要: A liquid preparation of a pharmaceutically active agent having a defined composation is repeatedly dosed from a multi-dose container having a defined volume. The amount dosed is selected as 1/N of the volume of the multi-dose container, N being an integer having a value of 2 or higher.A device for dosing a liquid preparation comprises a holder (1) for a multi-dose container (2), which has a movable rear wall (5) acting as a piston for expelling the liquid preparation (6) from the container, and a piston rod (7), which is provided with releasable blocking means (11, 14, 19, 22), such that the movement of the piston rod is limited to a preset length (35) corresponding to an expelled volume of 1/N of the volume of said multi-dose container, N being an integer having a value of 2 or higher.A preferred embodiment of the device is as an injection device for repeated parenteral injections from an injection cartridge.
