Abstract
Microparticle compositions comprising metal ion-lipid complexes for drug delivery are described including methods of making the microparticle compositions and methods of treating certain conditions and disease states by administering the microparticle compositions. The metal ion-lipid complexes can be combined with various drugs or active agents for therapeutic administration. The microparticle compositions of the present invention have superior stability to other microparticle compositions resulting in a microparticle composition with longer shelf life and improved dispersability. The microparticle compositions of the present invention have a transition temperature (Tg) of at least 20° C. above the recommended storage temperature (Tst) for drug delivery.
