| Abstract: | Objective To evaluate uncertainty in the dissolution rate of cefalexin tablets. Method according to recorded method in China pharmacopoeia 2010, dissolution rate of cefalexin tablets was examined. Factors influencing uncertainty were found out and each part uncertainty was calculated. Based on the determination results of uncertainty of, the risk was assessed. Result The average dissolution rate was 80.4%, and expanded uncertainty was 1.4% (k=2). The qualified rate of the dissolution rate was 22.1%. Conclusion When the results were in a critical value, uncertainty was analyzed and evaluated to ensure the scientificity and rationality of the results. |
