| Summary: | BackgroundPropranolol, a nonselective β-blocker, is the first-line treatment for infantile hemangioma (IH). Topical timolol has recently been proposed as a novel IH treatment with fewer adverse effects. This study was conducted to compare the efficacy and safety of oral propranolol and topical timolol for treating IH.MethodsStudies were included after searching PubMed, Embase, Web of Science, and the Cochrane Library via the keywords of "propranolol", "timolol", "infantile hemangioma" and their synonyms. A meta-analysis with pooled odds ratios was performed using the fixed-effect model.ResultsSeven articles with 2071 patients were included in this meta-analysis. Compared with topical timolol, oral propranolol had a greater response rate (OR = 2.12, P < 0.001), but it was also associated with a greater risk of adverse events (OR = 2.31, P < 0.001). For superficial IH, timolol demonstrated similar efficacy to propranolol (OR = 1.28, P = 0.34) but with fewer adverse events (OR = 2.30, P = 0.001). Additionally, compared with topical timolol, propranolol at a dosage of 2 mg/kg/d had a better response rate (OR = 2.62, P < 0.001), whereas the 1.0∼1.5 mg/kg/d propranolol group showed no significant difference (OR = 1.34, P = 0.38).ConclusionOral propranolol presents superior therapeutic efficacy in the treatment of IH compared to topical timolol. However, topical timolol can serve as an alternative to oral propranolol for treating superficial IH, providing similar efficacy with fewer adverse effects. Additionally, propranolol at a dosage of 2 mg/kg/d offers greater efficacy with a comparable safety profile, whereas the 1.0∼1.5 mg/kg/d propranolol dosage shows no significant difference in efficacy compared to timolol but is associated with more adverse events.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024603724, identifier CRD42024603724. |
