|Intravenous and oral antibiotics are not always effective for lung infections due to limited drug exposure at the infection site and bacterial resistance.
Researchers at Purdue University have developed a novel combination therapy of polymyxins for treating bacterial lung infections. Polymyxins have often been used as the last-line resort for infections caused by multi-drug resistant Gram-negative 'superbugs'; but inhaled polymyxins can cause toxicity in the lungs. The novel formulations developed by Purdue researchers create a powerful therapeutic option with better antibacterial killing and much-reduced toxicity than the currently used inhaled polymyxin B and colistin. Furthermore, the Purdue dry powder formulation shows promise as an inhaled therapy, with satisfactory stability and high aerosolization performance. These innovative inhalation formulations promise a life-saving option for patients suffering from bacterial lung infections, including people infected by multidrug-resistant Pseudomonas aeruginosa, Acinetobacter baumannii and Enterobacterales.
