The invention relates to a drug delivery device, comprising: a case for retaining drug container, the drug container defining a cavity for containing a drug, wherein a stopper is slidably disposed within the container so as to displace the drug through a discharge nozzle on translation in a distal direction, an inner magnet disposable within the drug container for abutting the stopper, at least one outer magnet disposed within the case coaxially with the container and slidable in an axial direction, a trigger arrangement for advancing the outer magnet in a distal direction on actuation, wherein the outer magnet and inner magnet are arranged for magnetically interacting through the drug container wall such the outer magnet advances the inner magnet on trigger actuation.
