Aztreonam for inhalation solution is an antibiotic medicine that works by killing bacteria. It does this by preventing the bacteria from making their cell walls. Because bacteria need their cell walls to survive, this action causes the bacteria to die.
Aztreonam for inhalation solution has been studied in a clinical trial that included people with cystic fibrosis who had the bacteria P. aeruginosa in their lungs. People in the study were randomly assigned to receive either aztreonam for inhalation solution or a placebo (a fake medicine with no active ingredients).
In this study, aztreonam for inhalation solution was shown to improve lung function more so than the placebo. In addition, people given the medication reported a greater improvement in their respiratory symptoms after 28 days of treatment than people given the placebo. This included improvements in coughing, wheezing, and mucus production. Children treated with aztreonam for inhalation solution had a greater improvement in respiratory symptoms than adults treated with the medication.
