The present disclosure relates to drug delivery devices, and in particular, to drug delivery devices configured to reconstitute a lyophilized drug powder into liquid form prior to delivery into a patients body. In some embodiments, such devices include a flexible drug reservoir having a proximal reservoir component storing a liquid diluent and a distal reservoir component storing a lyophilized drug powder, wherein the two compartments are separated by a frangible seal. A compression member may be positioned above the reservoir and held up by a releasable mechanism. When released, the compression member may be driven downwards to compress the proximal compartment so as to break the frangible seal and allow the diluent to mix with the drug powder and form a liquid drug mixture, and then to eject the liquid drug mixture from the reservoir.
