Preparation and Quality Control of Loxoprofen Sodium Patches / 中国药师

ABSTRACT

Objective:To study the preparation and quality control of loxoprofen sodium patches and develop an HPLC method for the determination of loxoprofen sodium. Methods:Loxoprofen sodium patches were prepared with CMC-Na and PVP as the adjuvants, and an HPLC method was used to determine the content of loxoprofen sodium. Results:The linear range of loxoprofen sodium was 4-24μg·ml-1(r=0. 999 7), the average recovery was 99. 99%(RSD=0. 99%, n=6). Conclusion:The preparation method is reason-able, simple and stable. The developed HPLC method is specific to determine the content of loxoprofen.
