Exploring the potential of a polyvinyl alcohol/chitosan-based nanofibrous matrix for erythromycin delivery: fabrication, in vitro and in vivo evaluation

This study aimed to investigate the potential of polyvinyl alcohol/chitosan nanofibers as a drug delivery system for erythromycin. Polyvinyl alcohol/chitosan nanofibers were fabricated using the electrospinning method and characterized using SEM, XRD, AFM, DSC, FTIR, swelling assessment and viscosity analysis. The in vitro drug release kinetics, biocompatibility, and cellular attachments of the nanofibers have been evaluated using in vitro release studies and cell culture assays. The results showed that the polyvinyl alcohol/chitosan nanofibers displayed improved in vitro drug release and biocompatibility compared to the free drug. The study provides important insights into the potential of polyvinyl alcohol/chitosan nanofibers as a drug delivery system for erythromycin and highlights the need for further investigation into the development of nanofibrous drug delivery systems based on polyvinyl alcohol/chitosan for improved therapeutic efficacy and reduced toxicity. The nanofibers prepared in this approach use less antibiotics, which may be beneficial to the environment. The resulting nanofibrous matrix can be used for external drug delivery applications, such as wound healing or topical antibiotic therapy.
