        Vancomycin Loaded Gelatin Microspheres Containing Wet Spun Poly(ε-caprolactone) Fibers and Films for Osteomyelitis Treatment

        Eda Ayse Aksoy,Betul Suyumbike Yagci,Gulseher Manap,Ipek Eroglu,Sukru Ozturk,Melike Ekizoglu,Kezban Ulubayram 한국섬유공학회 2019 Fibers and polymers Vol.20 No.11

        In this study, it was aimed to develop drug eluting biodegradable and biocompatible bone supportive fibers andfilms, which can locally be applicable on the infected bone defect area for osteomyelitis treatment. For this purpose,vancomycin (Vm) loaded gelatin (G) microspheres were prepared and dispersed into poly(ε-caprolactone) (PCL) solutionand then the suspension was processed as films and fibers by solvent casting and wet spinning techniques, respectively. Themean particle size distribution and morphology of Vm loaded G microspheres were characterized by laser diffraction methodand scanning electron microscopy, respectively. In vitro Vm release profiles and release kinetics from microsphere, fiber andfilm formulations were investigated. In vitro biodegradation properties of fiber and film formulations were examined in bothhydrolytic and enzymatic media during 25 days period. The cytotoxicity of Vm eluting films and fibers were tested on L929cells by MTT assay. Presence of PCL in film and fiber formulations retarded the release of Vm from microspheres andprovided long term sustained release. Vm eluting films and fibers exhibited strong antibacterial properties againstStaphylococcus aureus and Staphylococcus epidermidis.
