| 摘 要： | 目的评价复方苯佐卡因凝胶的局部刺激性和致敏性。方法依照国家食品药品监督管理局《化学药物刺激性、过敏性和溶血性研究技术指导原则》（以下简称指导原则），采用大鼠口腔黏膜刺激性实验法、兔眼刺激性实验法以及豚鼠皮肤致敏实验法。结果复方苯佐卡因凝胶给大鼠口腔正常黏膜连续涂药3次，相当于3g·kg-1，均无刺激和毒性反应；一次性按每只0．1g给兔眼结膜涂药，亦未出现刺激性反应；给每只豚鼠皮肤0．2g致敏接触和激发接触，均无过敏反应发生。结论复方苯佐卡因凝胶对口腔黏膜无刺激性，对皮肤也没有致敏性。

| Abstract: | Objective To evaluate the topical irritation and sensitization of Benzocaine compound gel. Methods Irritation tests of rat oral mucosa, rabbit eyes, and skin hypersensitivity tests in guinea pigs were used, in accordance with the ＇Guidance for Irritation, Sensitization and Hemolytic Tests for Chemicals＇ by the State Food and Drug Administration. Results By application of 3 g·kg-1 to rat oral mucosa, or 0.1 g to rabbit eyes, Benzocaine compound gel exhibited no irritation or other toxicity. No sensitization was found when 0.2 g of the gel was ap- plied to the guinea pig skin. Conclusion Benzocaine compound gel is not irritative to oral mucosa, and does not cause skin allergy. |
