| Abstract: |
| OBJECTIVE To establish a method for microbial limit test of cefprozil APIs, and carry out the verification of methodology. METHODS According to the method of Chinese Paharmacopoeia 2010, microbial limitexamination of three batches of cefprozil APIs were studied. Low speed centrifuge, membrane filtration and enzyme neutralization method were used with count of bacterium and pathogenic bacteria test. The plate method was used with counts mold and yeasts. RESULTS The recoveries above 70% were obtained when comparing the product challenge to its corresponding inoculum control, and no growth was observed in the negative diluent controls. The Method could pass the validation test of Chinese Pharmacopoeia 2010 version. CONCLUSION The method can be used in microbial limit test of cefprozil APIs. |
