Azithromycin-loaded respirable microparticles for targeted pulmonary delivery for the treatment of pneumonia

(A) AZM loaded FDKP microparticles (AZM@FDKP-MPs) were formulated and compared for their aerodynamic behaviors to optimize the effectiveness of pulmonary delivery. (B) AZM@FDKP-MP powders were loaded in an HPMC capsule and inhaled deep into the lung via a pierce capsule shell with a DL-D01 device.327
