Study on stability of Cyticoline Sodium Tablets

Objective To obtain stability data of Cyticoline Sodium Tablets under different surroundings through experiments,providing basis for drug storage and determination of expiration date.Methods The content of cyticoline sodium in Cyticoline Sodium Tablets was detected by HPLC.The stability of Cyticoline Sodium Tablets was determined by light test,high-temperature test,high-humidity test,accelerated test and long-term test.K25 ℃ was calculated by arrhenius equation and the statistical principle and the expiration date was predicted.Results Cyticoline Sodium Tablets were stable.The result of long-term tests was consistent with the predicated expiration date.Conclusion The expiration date of Cyticoline Sodium Tablets was 36 months under room temperature.
