Abstract
A drug delivery system includes an automatic injector that can deliver a small, precise amount of a therapeutic agent. The automatic injector includes a chamber for containing a liquid component and a thin porous member that carries thereon and/or therein the small, precise amount of therapeutic agent. Upon activation of the automatic injector, a flow path opens from the chamber through the porous member, enabling the liquid component to rapidly mix with the therapeutic agent before being injected.
