摘要
目的 :评价国产琥珀酸罗哌卡因粉针剂及进口盐酸罗哌卡因注射液的药效学特征 ,为临床应用提供实验依据。方法 :琥珀酸罗哌卡因临床主要用于外科手术麻醉、局部麻醉等 ,我们对两药进行了 4种动物模型药效学实验研究。结果 :两药在相同剂量下的表面麻醉、浸润麻醉、传导麻醉及椎管麻醉作用相近 ,麻醉浓度和麻醉效能间呈现良好的量效关系。经统计学分析 ,两药 EC50 之间无显著差异。结论 :认为国产琥珀酸罗哌卡因可以成为进口盐酸罗哌卡因注射液理想的代用品。
Object: To evaluate the features of the pharmacological effects of ropivacaine chelidoninic acid as well as imported hydrochloride ropivacaine and provide experimental basis for clinical use. Methods: Ropivacaine chelidoninic acid is mainly used as a surgical operation anesthesia or local anesthesia. The pharmacological experiments with four types of animal models were carried out for both drugs. Results:Under the same dosages, the effects of two drugs on surface anesthesia, infiltration anesthesia, conduction anesthesia and intravertebral anesthesia were similar. There were a good relationship between the concentration and the effects. The statistic analysis showed no remarkable differences in EC50 for two drugs. Conclusion: Consequently, the imported hydrochloride ropivacaine injection may be substituted by ropivacaine chelidoninic acid.
