研究不同粘合剂对药用炭颗粒吸着力的影响。方法 以淀粉、糊精、明胶和羧甲基纤维素钠(CMC-Na)为粘合剂,制成药用炭颗粒,根据中国药典2000版所载方法测定其吸着力。结果 不同含量的淀粉、糊精、明胶均会降低药用炭颗粒的吸着力,而8％～10％CMC-Na能增强药用炭颗粒的吸着力。结论 粘合剂可显著影响药用炭颗粒的吸着力,其中以CMC-Na比较理想。 The effect of different binders on the sorption of medicinal charcoal particles was studied. Methods Starch, dextrin, gelatin and sodium carboxymethylcellulose (CMC-Na) were used as binders to prepare medicinal charcoal granules. Their adsorption was measured according to the method of Chinese Pharmacopoeia 2000 edition. Results Different contents of starch, dextrin and gelatin all decreased the sorption capacity of medicinal charcoal granules, while CMC-Na 8% -10% increased the charpy of medicinal charcoal granules. Conclusion Adhesives can significantly affect the adsorption of medicinal charcoal particles, of which CMC-Na is more ideal.
