    Abstract：Objective To prepare dipotassium glycyrrhizinate eye drops for the treatment of non-infectious ocular inflammation. Methods The formula and preparation process of the eye drops were optimized, and the quality standard was drafted. The determination of dipotassium glycyrrhizinate by HPLC was established. The stability and local irritation tests were performed. Results The average recoveries of dipotassium glycyrrhizinate eye drops with high, medium and low concentrations were 100.32 %, 100.18 % and 100.12 % with RSD of 0.38 %, 0.31 % and 0.34 %, respectively. The samples were stable for 24 months in a long-term test and 6 months in an accelerated test, and had no irritation on rabbits’ eyes. Conclusion With a reasonable formula, stable preparation process, controllable quality and non-irritation, the dipotassium glycyrrhizinate eye drops prepared in this study can be applied in clinical trials. ......
