Purpose :
Antimicrobial resistance is a major health hazard worldwide. Combining azithromycin (AZ) and ciprofloxacin (CIP) in one
drug delivery system was proposed to boost their antibacterial activity and overcome resistance. This study aims to improve
azithromycin and ciprofloxacin activity by co-encapsulating them inside chitosan-coated polymeric nanoparticles and evaluating
their antibacterial activity
