USE OF SIMPLE AMINO ACIDS TO FORM POROUS PARTICLES |
摘要 |
Particles having a tap density of less than 0.4 g/cm<SUP>3 </SUP>include a hydrophobic amino acid or salt thereof and a therapeutic, prophylactic or diagnostic agent or any combination thereof. Preferred particles include a phospholipid, have a median geometric diameter between about 5 and about 30 microns and an aerodynamic diameter between about 1 and about 5 microns. The particles can be formed by spray-drying and are useful for delivery to the pulmonary system.
