Novel Self-Assembled Polycaprolactone-Lipid Hybrid Nanoparticles Enhance the Antibacterial Activity of Ciprofloxacin.

Ciprofloxacin (CIP), a widely used antibiotic, is a poor biopharmaceutical resulting in low bioavailability. We optimized a CIP polymer-lipid hybrid nanoparticle (CIP-PLN) delivery system to enhance its biopharmaceutical attributes and the overall therapeutic performance. CIP-PLN formulations were prepared by a direct emulsification-solvent-evaporation method.
