| 摘要: |
| 目的 探索盐酸卡替洛尔滴眼液中苯扎氯铵的最适添加浓度。方法 根据苯扎氯铵药敏试验结果，选择抑菌剂浓度5~70 μg·mL-1的盐酸卡替洛尔滴眼液进行初步抑菌效力考察，筛选出适宜的抑菌剂添加量。分别于不同苯扎氯铵浓度的盐酸卡替洛尔滴眼液中加入一定浓度的金黄色葡萄球菌、大肠埃希氏菌、铜绿假单胞菌、白色念珠菌菌悬液和黑曲霉孢子悬液，进行挑战实验，测试上述微生物在不同时间点的存活情况。结果 苯扎氯铵40 μg·mL-1对5种挑战微生物的生长有良好的抑制作用，且为最低有效剂量。结论 苯扎氯铵40 μg·mL-1可作为盐酸卡替洛尔滴眼液中抑菌剂的最适添加浓度。 |

| Abstract: |
| OBJECTIVE To investigate the optimal concentration of benzalkonium chloride that added to carteolol hydrochloride eye drops. METHODS According to the minimum inhibitory concentration of benzalkonium chloride. The initial bacteriostatic effect of carteolol hydrochloride eye drops with the concentration of 5-70 mg·mL-1 was investigated, and the appropriate amount of bacteriostatic agent was selected. In addition, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and Aspergillus niger spore suspension were added to test the survival of the above microorganisms in different periods of time. RESULTS Benzalkonium chloride 40 μg·mL-1 had a good inhibitory effect on the growth of 5 challenging microorganisms and it was the lowest effective dose. CONCLUSION Benzalkonium chloride 40 μg·mL-1 can be used as optimal concentration of bacteriostatic agent in carteolol hydrochloride eye drops. |
