Abstract :
[en] To maximize the efficacy of chronic osteomyelitis antibiotherapy while reducing antibiotic systemic toxicity, as well as time and costs of hospitalizations, it has been thought that monoolein-water gels incorporating gentamicin sulfate could be used as local, bioresorbable,and sustained-release implants. For this purpose, four formulations were examined with regard to their physicochemical and in vitro drug release characteristics. Hot stage microscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA),and X-ray diffraction showed cubic liquid crystalline and eutectic structures. The more suitable formulation consisting of 80-15-5%wt/wt monoolein-water-gentamicin sulfate progressively released the antibiotic for a period of 3 weeks without burst effect. Moreover, the content and the release profile of gentamicin sulfate were not significantly changed after storage at 2-6 degrees C for a period of 10 months.
