The invention belongs to the field of analytical chemistry, in particular to a method for testing the dissolution curve of amoxicillin-clavulanate potassium dispersible tablets. (1) Through the tests of system applicability, solution stability, linearity, and filter membrane influence factors, etc., determine the test method for high performance liquid phase detection of dissolution; (2) Through the tests of dissolution medium, stirring speed and sampling time point, etc. , to determine the detection method of the dissolution curve; (3) adopt the dissolution curve determination method; adopt the comparative dissolution curve similarity f 2 The factor carries out the comparison of reference sample (sample 1) and 2,3,4,5 sample dissolution curves, and realizes the present invention. The present invention has the advantages of establishing a discriminative dissolution test method, which can well distinguish the impact of the prescription or process variables on the in vitro release of the immediate-release dosage form drug amoxicillin-clavulanate potassium dispersible tablet, thereby ensuring the quality of the drug , to achieve the consistency of quality and efficacy.
