Aim: A polymeric in situ gelling delivery system for localized and sustained delivery to jawbone infections was developed. Materials & methods: In situ gelling delivery systems were prepared using either Poly(dl-lactic acid) or chitosan and Pluronic F127/Pluronic F68. Metronidazole nanoparticles were prepared using poly(dl-lactide-co-glycolide) or chitosan. Poly(dl-lactide-co-glycolide) was used for microparticles. Particles were characterized for size, charge and morphology. Results: Viscosity and yield stress of the gels were 0.4 Pa.s and 2 Pa, respectively, with 70% cell viability over 72 h. Around 90% of loaded metronidazole was released at a sustained rate over 1 week. Conclusion: Use of appropriate amount of nano/microparticles in the gel resulted in a sustained release over a period of 1 week - needed for jawbone infection.
