The present invention is directed to an automatic injection device containing a pre-loaded charge of medicament for automatically self-administering the medicament upon actuation thereof. The injection device includes a housing assembly, a dry compartment located within the housing for storing a predetermined dry charge of dry medicament therein, and a wet compartment located within the housing for storing a predetermined amount of liquid injection solution therein. The injection device further includes an activation assembly that enables the pressurization of the liquid injection solution in the wet compartment. The activation assembly also enables the compression of the dry medicament within the dry compartment upon activation of the automatic injection device. The activation assembly further facilitates passage of the liquid injection solution from the wet compartment to the dry compartment upon activation of the automatic injection device.
