摘要
目的 观察布他比妥,醋氨酚和咖啡因联用的历时性镇痛作用.方法 选用大鼠和小鼠两种动物,通过甩尾法、热板法和尾尖部压痛法等试验,设大剂量,中剂量和小剂量,并设对照组 (氨酚待因组和溶剂对照组),观察布他比妥,醋氨酚和咖啡因联用的镇痛作用,其联用比例约为1.25:8.1:1.结果 小鼠联用剂量在53~107mg·ke^(-1)(ig)和大鼠在84~42mg·kg^(-1)(ig)范围内,联合镇痛作用与氨酚待因(小鼠73mg·kg^(-1)(ig);大鼠57mg·kg^(-1),(ig)相当;小剂量组弱于氨酚待因组.在用药30min已有镇痛作用,在用药1h达高峰,2h后作用明显降低,4h时作用已消失.大、中剂量组与小剂量组间呈现一定的量效关系.结论 布他比妥,醋氨酚和咖啡因联用具有较强的镇痛作用,其作用潜伏期为0.5h,药效达峰为服药后1h,作用时程小于4h.
Aim To observe the timed analgesic effects by butabital (B), acetaminophen(A) and caffeine (C) in combination (BAC), in which the proportion was fixed as1. 25∶ 8. 1∶1. Method Three types of experimental methods, including the tailflicking method, the hot plate method and the pressurizing tail method, weretaken to determine indices at different times after the animals were adminstered(ig) high, median and low BAC dose. Results and conclusion BAC had a stronganalgesic effect in three types of experiments. The effect began 30 min after ad-ministration, arrived maximum at 1 h, decreased at 2 h and disappeared at 4 h.There was a dose-effect relationship between large and little BAC dose.
