Abstract
The present invention is antibiotic compositions, ventilator based systems and methods relating to ventilator-associated pneumonia (VAP) and ventilator associated tracheal (VAT) bronchitis. Antibiotic combinations of fosfomycin and an aminoglycoside, preferably amikacin, are administered via an in-line nebulizer within the airway of the ventilator. Humidified conditions create an improved aerosol mist to treat VAP and VAT.

A composition comprising:
- a first component comprising an isolated portion of amikacin having a concentration greater than 100 mg/ml and a pH between about 4.5 and about 6.0, a second component comprising an isolated portion of at least 40 mg of fosfomycin disodium, wherein the fosfomycin disodium is reconstituted from a powder to yield a solution having a concentration greater than 110 mg/ml in a pH solution about 8.0 and 9.5, and wherein the first component and the second component are sealed in separate containers prior to being combined to yield an admixture having a pH between 6.9 and 7.4, and osmolality between about 680 about 780 mOsmol/L, a chloride ion concentration greater than 20 meq/L and wherein the weight ratio of amikacin:fosfomycin disodium is greater than 1:1.
