Summary

Aerosol antibiotic administration offers the theoretical advantages of achieving high drug concentration at the infection site and low systemic absorption, thereby avoiding toxicity. Antibiotic aerosolization has good results in patients with cystic fibrosis, but data are scarce for patients under mechanical ventilation.

Prospective, randomized 1:1, open-label study to assess the microbiological cure and pharmacokinetics (PK), safety and efficacy of nebulized Aztreonam lysine (75 mg dose) each 8 hr during 5 days in ventilated patients heavily colonized by Gram-negative bacteria. It is planned to include a total of 20 ventilated patients heavily colonized. Only ten of them (active group) will receive 5 days of treatment with nebulized AZLI.The control group will not receive treatment.

DEVICE

Aerogen Solo

Aerogen's vibrating mesh technology, available within the Aerogen® Solo has been adopted for use of conventional mechanical ventilation. Aerogen Solo utilizes active vibrating mesh technology, where energy applied to the vibrational element, causes vibration of each of the 1000 funnel shaped apertures within the mesh. The mesh acts as a micropump drawing liquid through the holes producing a low velocity aerosol optimized for targeted drug delivery to the lungs. According our study (Rodriguez A et al , Expert Opin Drug Deliv. 2017 Dec;14(12):1447-1453) Aeroneb Solo showed an excellent aerosol delivery profile for Aztreonam lysine (AZLI) in an in vitro model of MV with short drug delivery time.

DEVICE

CombiHaler

The inhalation chamber CombiHaler™ spacer for mechanical ventilation and critical care (ICU) allows using both a vibrating mesh nebulizer such as Aeroneb ™, and a pMDI. It saves 50% of the nebulized drug when used in invasive ventilation. The inhalation chamber CombiHaler® is integrated on a circuit of a breathing device in invasive ventilation in particular for connexion of an Aeroneb® Pro or an Aeroneb® Solo. According our study (Rodriguez A et al , Expert Opin Drug Deliv. 2017 Dec;14(12):1447-1453) a better aerosol delivery performance (30%) was obtained using the Conbihaler spacer.
