| Abstract:Objective To improve the preparation method for furacillin solution and observe the stability of the solution.Methods The original preparation technics was modified.The furacillin solution was qualitatively analyzed by observation and quantitatively determined by UV spectrophotometry.Results The furacillin solution prepared in new method was proved to be stable in quality,without separating sediments in 4 months.However,sediment of furacillin solution prepared in old method was observed,color of the solution became deeper and content was out of quality 2 months later.Conclusion Improved method is convenient and feasible,which could increase the stability and ensure the safety and efficacy of furacillin solution in clinical use. |
