    摘要: Drug delivery device comprising a housing retaining a primary drug delivery assembly for the delivery of a primary medicament with a primary dose setting member configured to rotate in a helical movement to set a dose of the primary medicament and a secondary drug delivery assembly for the delivery of a secondary medicament. A dose dial is movable between a first position and a second position in axial direction and is rotationally constrained with respect to the housing when moved from the first position into the second position and is rotationally constrained to the primary dose setting member in the second position for setting a dose of the primary medicament. A secondary drive sleeve of the secondary drug delivery assembly serves for dispense of the secondary medicament. The dose dial and the secondary drive sleeve can be coupled for dose setting.
