摘要：扑热息痛是一种疗效确切且副作用较小的解热镇痛药，在全世界范围内被广泛地使用。本文选用交联聚乙烯吡咯烷酮、羧甲基淀粉钠、玉米淀粉作为崩解剂，采用湿法制粒制备扑热息痛片剂。对含有不同崩解剂的扑热息痛片进行质量检查，包括外观、片重差异、硬度、脆碎度、崩解时限和溶出度，通过比较崩解时限和溶出度来选择最佳处方。实验结果表明，以玉米淀粉作为崩解剂的扑热息痛片具有外表美观光洁、硬度适中、脆碎度优良、崩解时限短和溶出度高等优点，是制备扑热息痛片的最佳处方。41672

Experimental study of disintegrating agents in Paracetamol tablets
Abstract: Paracetamol, an effective analgesia-antipyretic drug with few side effects, is widely used around the world. In this paper, cross-linked polyvinyl pyrrolidone, carboxymethyl starch sodium, corn starch were chosen as the disintegrating agents to prepare paracetamol tablets by the mean of wet granulation, and do quality inspection for these tablets, including appearance, tablet weight variation, hardness, friability, disintegration and dissolution rate, and the formulas were screen by disintegration time and dissolution rate. The results showed that the tablets with corn starch as disintegrating agent have the shortest disintegration time, high dissolution rate, excellent appearance, suitable hardness and friability. It is the best formula to prepare paracetamol tablets.
Key Words: paracetamol tablets; the best prescription; disintegration; dissolution rate; starch
