Timolol maleate 0.5% gel is a safe and effective medication for treating superficial infantile hemangiomas (IHs) in infants with a median age of 9 weeks.
Forty-one infants who had superficial IHs without ulceration and not near mucosal surfaces were recruited and randomly assigned to placebo and treatment (timolol maleate 0.5% gel) groups. Efficacy was assessed by performing blinded volume measurements at weeks 0, 1, 2, 3, 4, 8, 12, 16, 20, and 24 and blinded investigator photograph scoring at weeks 0, 12, and 24. Safety was assessed by measuring heart rate and systolic and diastolic blood pressure at weeks 0, 1, 2, 3, 4, 8, 12, 16, 20, and 24.
Fifteen of the 19 infants receiving treatment and 17 of the 22 infants receiving placebo completed the study. Significant color change on the blinded photographic scores was noted at week 24 of the study (P = .003). There was a significantly higher proportion of treated IHs that reduced in size by >5% at weeks 20 and 24 (P < .02). The predicted proportion of IH volume change was also significantly less for treated IHs from week 16 onward when compared with placebo (P < .05). There was no significant variation in blood pressure and heart rate between the groups.
Topical timolol maleate 0.5% gel with a maximum dose of 0.5 mg per day is a safe and effective option for small superficial IHs that have not ulcerated and are not on mucosal surfaces.
马来酸噻吗洛尔 0.5%凝胶是一种安全有效的药物,适用于治疗 9 周龄婴儿的浅表性婴幼儿血管瘤(IHs)。
招募了 41 名无溃疡且不在黏膜表面的浅表性 IHs 婴儿,并将其随机分配至安慰剂和治疗(马来酸噻吗洛尔 0.5%凝胶)组。通过在第 0、1、2、3、4、8、12、16、20 和 24 周进行盲法体积测量,并在第 0、12 和 24 周进行盲法研究者照片评分,评估疗效。通过在第 0、1、2、3、4、8、12、16、20 和 24 周测量心率和收缩压及舒张压,评估安全性。
19 名接受治疗的婴儿中有 15 名和 22 名接受安慰剂的婴儿中有 17 名完成了研究。研究第 24 周时,盲法照片评分的颜色变化显著(P =.003)。治疗组中有较大比例的 IH 在第 20 和 24 周缩小了>5%(P <.02)。与安慰剂相比,从第 16 周开始,治疗组 IH 体积变化的预测比例也显著降低(P <.05)。两组之间血压和心率无显著差异。
