STABLE METAL ION-LIPID POWDERED PHARMACEUTICAL COMPOSITIONS FOR DRUG DELIVERY

摘要

A microparticle for drug delivery comprises an active agent and an excipient, the excipient comprising a metal ion-lipid complex. The metal ion is chosen from the group consisting of lanthanide metals, actinide metals, group IIa and IIIb metals, transition metals or mixtures thereof. The lipid comprises a phospholipid. The complex results in a glass transition temperature increase of the microparticle.
