本实验运用镇痛药理指标来探讨天麻钩藤饮等平肝熄风三方的体内药物动力学过程与参数。在试用两倍临床等效剂量时，三方对醋酸所致小鼠扭体反应均具有一定的抑制作用，并呈相应的量效关系。天麻钩藤饮的最低起效剂量为０４２ｇ／ｋｇｐｏ，相当于临床等效剂量的效应消退半衰期为０５１小时，效应维持时间为４３０小时，体存血药浓度达峰时间为０９４小时。镇肝熄风汤相应为０１１ｇ／ｋｇｐｏ，０５０小时，１３８０小时（达峰时间未能测算出）；建瓴汤相应为０２２ｇ／ｋｇｐｏ，０６６小时，１１３２小时，１９８小时。此外，还就研究方法学及该类方剂的临床运用等问题作了探讨 In this experiment, pharmacological indicators of analgesia were used to investigate the in vivo pharmacokinetics and parameters of Tianma Gouteng Yin et al. In the trial of twice the clinical equivalent dose, the three parties have a certain inhibitory effect on the writhing response of mice induced by acetic acid, and showed a corresponding dose-effect relationship. The minimum effective dose of Tianma Gouteng Decoction is 0.44g/kgpo, which is equivalent to the clinically equivalent dose effect half-life of 051 hours, and the effect maintenance time is 430 hours. 094 hours. Zhen Xi Xi Feng Tang corresponding to 0  11g/kgpo, 0  50 hours, 13  80 hours (peak time can not be measured out); Jianshe soup corresponding to 0  22g/kgpo, 0  66 hours, 11  32 hours, 1  98 hours. In addition, we also discussed the research methodology and the clinical application of such prescriptions.
