pH值对磺胺嘧啶银乳膏稳定性的影响

Influence of pH on the Stability of Sulfadiazine Silver Cream

目的 :考察不同pH值的磺胺嘧啶银乳膏稳定性。方法 :观察不同厂家的硬脂酸配制的磺胺嘧啶银乳膏外观变化及不同pH值的磺胺嘧啶银乳膏的外观变化。结果 :pH <8.0时 ,磺胺嘧啶银乳膏的稳定性较好。结论 :磺胺嘧啶银乳膏应检查其pH值。

Objective:To survey the influence of different pH on the stability of sulfadiazine silver cream. Methods:Changes in the outward appearance of sulfadiazine silver creams dispensed with stearic acid by different factories, as well as changes in outward appearance of sulfadiazine silver creams with different pH were kept under observation. Results:It was shown that sulfadiazine silver cream with a pH value of 8 would have a fairly good stability. Conclusion:pH of sulfadiazine silver cream should be checked.
