Emerging Opportunities for Inhaled Antibiotic Therapy

Abstract

Cipolla D, Froehlich J and Gonda I

Inhaled antibiotics have become a mainstay of cystic fibrosis (CF) therapy by providing high drug concentrations locally in the lung while minimizing systemic exposure and thus the potential for side effects. In CF, inhaled antibiotics decrease the rate of decline of lung function, improve the quality of life, and reduce the frequency of exacerbations and hospital admissions. However, the burden of therapy remains high in CF. There is an opportunity for more convenient and effective inhaled antibiotics to reduce the disease burden in CF. In contrast, despite the unmet medical need, no inhaled antibiotics are approved for lung infections in a number of other diseases including non-CF bronchiectasis, COPD, melioidosis, pneumonic plague, anthrax, Qfever, tularemia and patients with other infections including non-tuberculous mycobacteria. This review discusses the progress towards achieving that goal in those indications. Additionally, the approved inhaled antibiotics in CF are only available as a fixed dose that is inhaled twice or thrice daily. There is a limited opportunity to personalize therapy to the patient. This review envisions a future scenario where the treatment of lung infections can be optimized to the specific needs of each individual based on the attributes of their infectious agents.
