目的 以药效作用值为指标，对双黄连口服液、双黄连片剂及双黄连颗粒药效进行再评价。方法 测定并计算双黄连口服液、双黄连片剂及双黄连颗粒药效作用值，并采用经典的抗炎、解热及体外抑菌药效模型对这3种制剂药效进行验证。结果 双黄连口服液、双黄连片及双黄连颗粒抗炎药效作用值分别为2.80、3.57、2.66 mg，解热药效作用值分别为9.59、14.86、13.42 mg，抗菌药效作用值分别为996.72、2 011.64、1 691.98 mg，表明双黄连片抗炎作用、解热及抗菌作用最强，体内外药效研究也表明双黄连片在抗炎、解热及抗菌作用方面较其他2种剂型显著。结论 双黄连3种制剂的药效实验验证结果与其药效作用值预测结果一致，药效作用值可作为双黄连系列制剂药效作用再评价研究的指标。

Objective To re-evaluate the pharmacodynamics of Shuanghuanglian Oral Liquid, Shuanghuanglian Tablet, and Shuanghuanglian Granules with the index of pharmacodynamics action value. Methods The pharmacodynamics action values of Shuanghuanglian Oral Liquid, Shuanghuanglian Tablet, and Shuanghuanglian Granules were determined and calculated. And the classical models of anti-inflammatory, antipyretic and antibacterial in vitro were used to verify the effect of these three preparations. Results The pharmacodynamics action values of anti-inflammatory effect of Shuanghuanglian Oral Liquid, Shuanghuanglian Tablet, and Shuanghuanglian Granules were 2.80, 3.57, and 2.66 mg, respectively; The pharmacodynamics action values of antipyretic effect were 9.59, 14.86, and 13.42 mg respectively; The pharmacodynamics action values of antibacterial effect were 996.72, 2 011.64, and 1 691.98 mg respectively, which indicated that Shuanghuanglian Tablet had the strongest anti-inflammatory, antipyretic, and antibacterial effect, and the results of pharmacodynamics in vivo and in vitro studies also showed that Shuanghuanglian Tablet had better anti-inflammatory, antipyretic, and antibacterial effects than the other two preparations. Conclusion In this study, the pharmacodynamic test verification results of these three preparations were consistent with the predicted results of pharmacodynamics action value. Therefore, the pharmacodynamics action value can be used as an index to re-evaluate the effect of Shuanghuanglian series preparations.
