SYSTEMS FOR TREATING PULMONARY INFECTIONS
Provided herein are systems for treating a subject with a pulmonary infection, for example, a nontuberculous mycobacterial pulmonary infection, a Burkholderia pulmonary infection, a pulmonary infection associated with bronchiectasis, or a Pseudomonas pulmonary infection. The system includes a pharmaceutical formulation comprising a liposomal aminoglycoside dispersion, and the lipid component of the liposomes consist essentially of electrically neutral lipids. The system also includes a nebulizer which generates an aerosol of the pharmaceutical formulation at a rate greater than about 0.53 gram per minute. The aerosol is delivered to the subject via inhalation for the treatment of the pulmonary infection.
1 - 29 . (canceled)
30 . A method for treating or prophylaxis against a pulmonary infection in a patient, the method comprising:
aerosolizing a pharmaceutical formulation comprising a liposomal complexed aminoglycoside, wherein the pharmaceutical formulation is an aqueous dispersion and is aerosolized at a rate greater than about 0.53 gram per minute, and
administering the aerosolized pharmaceutical formulation to the lungs of the patient;
wherein the aerosolized pharmaceutical formulation comprises a mixture of free aminoglycoside and liposomal complexed aminoglycoside, and
the lipid component of the liposome consists of electrically neutral lipids, and
the MMAD of the aerosol is less than about 4.2 μm, as measured by the ACI, or less than about 4.9 μm, as measured by the NGI.
31 - 70 . (canceled)
71 . A liposomal aminoglycoside aerosol comprising an aminoglycoside and a liposome comprising DPPC and cholesterol, wherein about 65% to about 75% of the aminoglycoside is liposomal complexed and the liposomal aminoglycoside aerosol is generated at a rate greater than about 0.53 gram per minute.
