Devices and methods are disclosed which automatically reconstitute a drug, such as e.g., a lyophilized drug. A vial (30) containing the drug is fluidly coupled to a cartridge (12) containing a reconstitution liquid with a fluid conduit (14f), wherein an entry point is defined where the fluid conduit enters the vial (30). The device (10) automatically adjusts orientation of the vial (30) such that the entry point of the vial is gravitationally higher than the drug in the vial (30), and automatically transfers the reconstitution liquid out of the cartridge (12) and into the vial (30) to create a reconstituted drug. The device (10) also automatically adjusts the orientation of the vial (30) such that the entry point of the vial is gravitationally lower than the reconstituted drug, and automatically transfers the reconstituted drug from the vial (30) and into the cartridge (12).
