摘要: 目的 为使国内常用实验动物麻醉剂戊巴比妥钠符合国际使用要求,针对非药用级别戊巴比妥钠建立制剂配制方法,评价了三种不同溶剂配制的戊巴比妥钠制剂对SD大鼠的麻醉效果。方法 以三种不同溶剂系统分别配制了30 mg/ml和50 mg/ml戊巴比妥钠注射液,测定了各组戊巴比妥钠注射液的溶解性、pH、含量以及在室温和2~8℃保存的稳定性;三种不同溶剂配制的戊巴比妥钠制剂注射SD大鼠,收集有效麻醉时间和麻醉状态评价制剂的麻醉效果。结果 采用乙醇丙二醇和HS15溶剂配制浓度为30 mg/ml和50 mg/ml的戊巴比妥钠具有很好的溶解性;pH值稳定在9.6±0.2范围内;储存在室温和2~8℃30 d内均非常稳定;SD大鼠麻醉效果评价中,以乙醇丙二醇实验组麻醉时间短、个体差异小、达到理想麻醉效果的动物最多。结论 以乙醇丙二醇作为溶剂对非药用级别戊巴比妥钠的溶解性和稳定性都非常好,在动物麻醉效果上也最佳;HS15组次之。

Abstract: Objective In order to make the anaesthetic-pentobarbital that has been using on laboratory animals in domestic to meet international standard, established the preparation method for non-pharmaceutical grade sodium pentabarbital; Evaluated anesthetic effect of SD rat for three different solvent formulations. Methods Three different solvent systems were formulated 30mg/ml and 50 mg/ml pentobarbital sodium injection respectively, and tested dissolubility, pH, Conc. and the stability stored at room temperature and 2 ~ 8 ℃ of each pentobarbital sodium injection; Pentobarbital preparation with three different solvent are injected in SD rats, colleted valid duration of anesthesia and anesthetic state to evaluate anesthatic effection. Result The dissolubility of pentobarbital is great when prepared by Ethanol-Propylene glycol and HS15; The pH is stable on 9.6±0.2; the solution is very stable at room temperature and 2~8 ℃ during 30 days; For anesthetic effect evaluation of pentobarbital sodium injection in SD rats, the ethanol- propylene glycol group has short anesthesia time, minor individual differences, and the most animals reaching up to the ideal anesthetic effect. Conclusion The ethanol-propylene glycol as a solvent for the solubility and stability of the non-pharmaceutical grade sodium pentobarbital are very good, meanwhile it has the best animal anesthetic effect; the HS15 group followed.
