Novel inhalation formulations of polymyxins
Safer, more effective polymyxin formulations for treating superbug lung infections.
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.
