ABSTRACT

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 oftimolol maleate eye drops in superficial hemangioma infants,and exterior coating with 6 times a day may achieve the best curative effect.
