Abstract
A medicament container, such as an injection ampule, for multiple administration of medicament suspensions the containers is filled with medicament so as to be free of gas bubbles, and includes at least one inert mixing element of suitable size whose density is different from that of the suspension. The mixing element acts to homogenize the medicament suspension as the container is shaken.

A device for the administration of medicament suspensions comprising:
- a container for receiving an essentially gas-bubble-free medicament suspension;
- at least one mixing element disposed in said container, said mixing element being inert towards the suspension and having a density which is greater than the density of the suspension, said at least one mixing element being dimensioned relative to the size of said container such that the suspension is homogenized by shaking movements of said container.
