【Abstract】 AIM:To study the formulation, preparation, and quality control for the gatifloxacin injection. METHODS: The gatifloxacin injection was prepared using hydrochloric acid or sodium hydroxide as pH adjustment agents and sodium chloride as iso osmotic adjustment agents. The contents of gatifloxacin in the injection was determined by RP HPLC. RESULTS: The physico chemical stability was good after storing 10 d under high temperature (80 °C ), illumination (3600 lx) and 24 mo under indoor temperatuer. CONCLUSION:The selected formulation and preparation technique are good and can contribute to the development of the product. The method of quality control was accurate and reliable.更多还原
