Abstract

An aqueous or powder composition includes anti-gram-negative antibiotic or salt thereof being present at an amount ranging from about 100 mg/ml to about 200 mg/ml. Another aqueous or powder composition includes anti-gram-positive antibiotic or salt thereof being present at a concentration ranging from about 0.6 to about 0.9 of the water solubility limit, at 25° C. and 1.0 atmosphere, of the anti-gram-positive antibiotic or salt thereof. Other embodiments include unit doses, kits, and methods.

Claims

1. A kit comprising:

a unit dose comprising about 3 to 10 ml of a preservative-free liquid composition for aerosolization having a pH of about 5.5 to about 6.3 and a shelf life of at least two years at room temperature without the formation of precipitate, wherein the composition consists essentially of water and about 400 mg to about 750 mg amikacin, at a concentration of about 125 mg/ml;
