马来酸噻吗洛尔滴眼液治疗浅表型婴幼儿血管瘤用药方法的探讨

Usage and efficacy of timolol maleate eye drops in treatment of superficial infantile hemangioma

目的:探讨使用马来酸噻吗洛尔滴眼液治疗婴幼儿血管瘤的最佳用法与用量。方法:将250例浅表型婴幼儿血管瘤患者均分为5组;即外敷组和每日外涂2,4,6,8次组。观察不同用药方式(外敷及外涂)及不同用药频率对疗效的影响。结果:外敷马来酸噻吗洛尔滴眼液2次/d,每次30 min组的疗效优于外涂组2次/d(P<0.001),外涂2次/d或4次/d的疗效与外涂6次/d比较,差异有统计学意义(P<0.001),外涂6次/d的疗效与外涂8次/d或外敷2次/d之间比较,差异无统计学意义(P>0.05)。结论:马来酸噻吗洛尔滴眼液治疗婴幼儿血管瘤的疗效与用药量相关,6次/d外涂能达到最佳的疗效。

Objective：To determine drug dose and usage of timolol maleate eye drops in the treatment of superficial infantile hemangioma.Methods：A total of 250 superficial hemangioma infants were recruited and assigned into 5 groups（n=50 for each group）：an external application group and 4 exterior coating groups（2,4,6,8 times per day）.We evaluated the therapeutic effect of different methods for drug application（external application or exterior coating） and the frequency for drug administration on superficial infantile hemangioma.Results：The external application group（twice a day and 0.5 hour per time） showed better effect than that in the exterior coating group with twice a day（P〈0.001）.The difference in therapeutic effect between the exterior coating group with 6 times a day and exterior coating group with twice a day or with 3 times a day was significant（P〈0.001）.The differences in drug efficacy were not found among the exterior coating group with 6 times a day,the exterior coating group with 8 times a day,or the external application group with twice a day（All P〈0.05）.Conclusion：Drug dose may affect the therapeutic effect of timolol maleate eye drops in superficial hemangioma infants,and exterior coating with 6 times a day may achieve the best curative effect.
