A novel “counter ion complex” method was developed to overcome the low drug loading efficiencies of antibiotics in biodegradable PLGA nanoparticles. This intriguing approach enhanced drug loading efficiencies by altering solubility characteristics and distinguished itself to serve for development of pulmonary nanoformulations for treatment of cystic fibrosis (CF) infections owing to its higher antibiotic load to deliver to the site of action.
