A prospective study of topical carteolol therapy in Chinese infants with superficial infantile hemangioma

Abstract

Background/Objective

To report our observations from a trial of the short-term effectiveness and safety of topical carteolol hydrochloride drops to treat infantile hemangiomas (IHs).

Methods

From October 2012 to September 2015, the study recruited 349 children with superficial IHs. Participants were randomized to two groups: treatment (n = 224 who received 2% carteolol hydrochloride drops administered to the lesion surface twice daily) and observation (n = 125 who did not receive treatment). Therapy duration was 6 months.

Results

The mean age at the beginning of treatment was 3.2 months. Treatment responses were categorized as class 1 (total regression), class 2 (partial regression or controlled growth), or class 3 (no response). Of infants receiving carteolol treatment, 10.7% (24 patients) were categorized as class 1, 72.3% (162 patients) as class 2, and 17.0% (38 patients) as class 3. Of infants in the observation group, 5.6% (7 patients) were categorized as class 1, 25.6% (32 patients) as class 2, and 68.8% (86 patients) as class 3. No adverse effects were noted during treatment.

Conclusion

Carteolol is an effective, safe topical treatment for superficial IHs. Carteolol may be used to treat proliferative superficial IHs, particularly in infants younger than 6 months.
