6种改善枸橼酸钙片崩解度的方法比较

Comparison of Six Methods Ameliorating the Disintegration of Calcium Citrate Tablet

目的:比较几种改善构橼酸钙片崩解度的方法。方法:用6种方法制备枸橼酸钙片,测定、比较片剂的崩解度,并评价片剂外观、片重差异、硬度、脆碎度和稳定性等方面的质量指标。结果:增加崩解剂和减少润滑剂的用量不能显著地改善片剂的崩解度;减少粘合剂用量、外加崩解剂或构城酸钠粉末可使片剂硬度降低,脆碎度增加,且还会使片重差异增加。结论:减小颗粒粒径,能显著地改善片剂的崩解度,片剂的其他质量指标均符合规定。

OBJECTIVE: To compare several METHODS: ameliorating the disintegration of calcium citrate tablet .METHODS: To prepare calcium citrate tablet by six different METHODS: and to determine and evaluate the prepared tablet in respect to the apperance,difference in weight of tablets,hardness,friability and stability .RESULTS:The disintegration was not significantly ameliorated by increasing disintegrant or decreasing lubricant .The hardness was decreased and the friability was increased by decreasing the amount of binder or adding more disintegrant or crushing calcium citrate to powder.The two latter METHODS: increased the difference in weight of tablets.CONCLUSION:The optimal method to ameliorate the disintegration is to diminish the grain diameter and the other parameters of quality is able to be up to the standard.
