Topical Application of 0.5% Timolol Maleate Hydrogel for the Treatment of Superficial Infantile Hemangiomas

Oral propranolol is considered the first line therapy in the treatment of infantile hemangiomas (IHs). However, there are considerable side effects due to its ability to penetrate the blood brain barrier. Alternatively, topical timolol, a non-selective beta blocker, has resulted in fewer side effects and is 4–10 times more potent in comparison to oral propranolol. This study evaluates the efficacy of 0.5% timolol maleate hydrogel for the treatment of IH.

This study was conducted via a quasi-experimental design from October 30, 2020 – April 29, 2021, at the Department of Dermatology Benazir Bhutto Hospital, Rawalpindi. 145 infants between 1–12 months in age diagnosed with superficial cutaneous hemangiomas were included in the study with a male to female ratio of 2.4:1. A thin layer of timolol maleate 0.5% hydrogel was applied to the entire surface of the patient’s IH three times daily. Digital photographs and measurements of the hemangiomas were taken at one-month intervals for a maximum of 6 months.

The age range in this study was from 1–12 months with a mean age of 6.10 ± 2.52 months. The majority of the patients 89 (61.4%) were between 1–6 months of age. Of the 145 patients, 89 (61.4%) showed an excellent response, 44 (30.3%) showed a good response, and 12 (8.3%) showed no response to the topical 0.5% timolol maleate hydrogel treatment.

The use of topical 0.5% timolol maleate hydrogel is a promising therapeutic option for the treatment of superficial IHs. Anwar F, Mahmood E, Sharif S, et al.
