Preparation and characterization of a ciprofloxacin-loaded nanoparticles incorporated polymeric film dressing.

ABSTRACT: In an effort to prepare a modern polysaccharide-based dressing for sustained/prolonged delivery of the antibacterial agent to prevent and control skin wound infection, ciprofloxacin (CP)-loaded sodium alginate (SA)-chitosan (CS) nanoparticles (NPs) were incorporated into novel arabinoxylan (AX)-pectin (PC) blended polymeric films by solvent casting. The CP-NPs were prepared by a two-step ionic interaction method with < 300 nm size, about 25 mV zeta potential, 74% CP-loading efficiency, and approximately round shape. The CP-NPs were incorporated in optimized AX-PC polymeric film prepared by using 2% AX and 2% PC with a plasticizer (2% glycerol) and then these films were characterized for suitability as a film dressing. The transparency, improved mechanical strength, thermal stability, water transmission, and exudate uptake characteristics indicated that CP-NPs incorporated AX-PC polymeric films were suitable for dressing applications. The CP-NPs incorporated AX-PC films exhibited sustained CP release (90% release in 36 h) and better antibacterial susceptibility as compared to free CP-containing AX-PC films. Thus, CP-NPs incorporated AX-PC films are promising dressing materials to prevent and control wound infection with prolonged antibiotic release.

Project description:The encapsulation of peptides and proteins in nanosystems has been extensively investigated for masking unfavorable biopharmaceutical properties, including short half-life and poor permeation through biological membranes. Therefore, the aim of this work was to encapsulate a small antimicrobial hydrophilic peptide (H-Ser-Pro-Trp-Thr-NH2, FS10) in PEG-PLGA (polyethylene glycol-poly lactic acid-co-glycolic acid) nanoparticles (Nps) and thereby overcome the common limitations of hydrophilic drugs, which because they facilitate water absorption suffer from rapid degradation. FS10 is structurally related to the well-known RNAIII inhibiting peptide (RIP) and inhibits S. aureus biofilm formation. Various parameters, including different method (double emulsion and nanoprecipitation), pH of the aqueous phase and polymeric composition, were investigated to load FS10 into PEG-PLGA nanoparticles. The combination of different strategies resulted in an encapsulation efficiency of around 25% for both the double emulsion and the nanoprecipitation method. It was found that the most influential parameters were the pH-which tailors the peptides charge-and the polymeric composition. FS10-PEG-PLGA nanoparticles, obtained under optimized parameters, showed size lower than 180 nm with zeta potential values ranging from -11 to -21 mV. In vitro release studies showed that the Nps had an initial burst release of 48-63%, followed by a continuous drug release up to 21 h, probably caused by the porous character of the Nps. Furthermore, transmission electron microscopy (TEM) analysis revealed particles with a spherical morphology and size of around 100 nm. Antimicrobial assay showed that the minimum inhibitory concentration (MIC) of the FS10-loaded Nps, against S. aureus strains, was lower (>128 µg/mL) than that of the free FS10 (>256 µg/mL). The main goal of this work was to develop polymeric drug delivery systems aiming at protecting the peptide from a fast degradation, thus improving its accumulation in the target site and increasing the drug-bacterial membrane interactions.
