Summary Cefuroxime axetil is a mixture of two equally active isomers (50% each). A stability‐indicating high‐pressure liquid chromatography method for the quantification of cefuroxime axetil has been developed. The method is accurate, precise and reproducible. The percentage, relative standard deviation based on six injections was 1·2. Using the developed method, the chemical stability of cefuroxime axetil suspensions has been determined in three vehicles containing sugar and two without sugar. The results varied widely in the vehicles without sugar (up to ± 31%). In the viscous vehicles containing sugar, the variations in the results were only up to ±6%. The cefuroxime axetil in these suspensions was stable up to 28 days when stored at 5°C. In addition, pH values were stable and the physical appearances of the samples did not change.
