摘要：
Phospholipid based powders for drug delivery applications are disclosed. The powders may include a polyvalent cation in an amount effective to increase the gel-to-liquid crystal transition temperature of the particle compared to particles without the polyvalent cation. The powders are hollow and porous and are preferably administered via inhalation.
