Clinical applications of pulmonary delivery of antibiotics

Area of Science:

• Pulmonology
• Infectious Diseases
• Pharmacology

Background:

• Systemic antibiotic administration is standard for infections.
• Pulmonary infections are directly accessible via airways, allowing topical antibiotic delivery.
• Inhalation offers high local antimicrobial concentrations with potentially reduced systemic exposure.

Purpose of the Study:

• To review the evidence for aerosolized antibiotics in treating various pulmonary conditions.
• To highlight the established role in cystic fibrosis and emerging use in other infections.

Main Methods:

• Literature review of studies on aerosolized antibiotic therapy.
• Analysis of evidence for specific pulmonary infections.

Main Results:

• Aerosolized antibiotics are standard care for chronic infections in cystic fibrosis (CF).
• Increasing use is observed for non-CF bronchiectasis, non-tuberculous mycobacteria, and ventilator-associated infections.
• High local antibiotic concentrations are achieved with reduced systemic absorption.

Conclusions:

• Inhaled antibiotics provide targeted treatment for pulmonary infections.
• Evidence supports their use beyond CF, though indications vary.
• This delivery method optimizes antimicrobial efficacy at the infection site.
