Development of biodegradable scaffolds loaded with vancomycin micropartricles for the treatment of osteomyelitis

In this present research work, the development of biodegradable scaffolds loaded with Vancomycin micropartricles was carried out for the treatment of Osteomyelitis. Characterization Vancomycin Loaded microparticles and evaluation of the microparticles loaded scaffolds and also to carry out In-vitro release studies. Vancomycin hydrochloride microparticles were prepared with the help of double emulsion method. HPMC and Polaxomer 407 has been taken as the main polymers for the preparation of the microparticles. Chitosan was taken as the major polymer for the preparation of scaffolds for its greater biocompatibility and biodegradability. The preparation was done with the help of the solvent casting method. The formulation was taken for further characterization and evaluation studies. Fourier-Transform Infrared Spectroscopy and Differential scanning calorimetry were carried out for the pure vancomycin drug, and the chitosan polymer X-ray diffraction was carried out to check the crystallinity of the prepared scaffolds. The particle size, zeta potential and polydispersity index for vancomycin loaded microparticles were found to be 577.0±102.5 nm, 1624 mv and 0.254. The maximum and sustained release rate of the drug was found to be 95.6±0.478, at 16th Hr. By taking all the reports, a conclusion can be drawn that, the formulated VLM biodegradable scaffolds will show burst release at the initial time of administration, which is essential for the wound healing activity and will be sustained throughout the process of treatment of osteomyelitis.
