Abstract
Objective: The aim of this research is to formulate teicoplanin-loaded solid lipid nanoparticles (SLN) coated with chitosan to sustain teicoplanin release for effective antibacterial therapy.
Material and Method: “Double emulsion-solvent evaporation technique was used for the production of SLNs. The nanoparticles were characterised in terms of morphology, size, encapsulation efficacy, in-vitro drug release and antibacterial activity studies after optimization of process and formulation parameters.
Result and Discussion: Transmission electron microscopy images confirmed the formation of spherical SLNs. With chitosan coating, the size increased (from 80 nm to 106 nm) and the negative value of zeta potential (- 11.29) changed to positive (+34.41). The in-vitro release data showed prolonged release of teicoplanin from optimized SLN and chitosan-coated SLN (c-SLN) formulations over 1 week. The antibacterial activity study (S. aureus and Methicillin-resistant S. aureus) showed the activity of the teicoplanin loaded SLN formulations. In conclusion, this study demonstrated the potential of c-SLN for effective delivery of teicoplanin.
