Background: Infantile hemangioma is the most common tumor of infancy. Currently, propranolol is a preferred drug for treating hemangioma. The exact mechanism of action of propranolol is not known. In this study, we attempted to assess whether propranolol has any effect on vascular endothelial growth factor (VEGF) and tissue inhibitor of metalloproteinase-2 (TIMP-2) over a period of time, and if it is there, how long it affects it. Materials and Methods: Propranolol was administered in the dosage of 2–3 mg/kg. The first serum sample was collected before starting the propranolol treatment. Thereafter, samples were collected at monthly intervals up to a total of six samples. The samples were assessed for TIMP-2 and VEGF using enzyme-linked immunosorbent assay kit. Results: The duration of this study was from June 2016 to November 2017. The total number of patients in this study was 15. Thirteen patients responded to treatment. The mean age of patients was 7.1 months. The mean value of baseline VEGF was 0.234 ± 0.059 and that of TIMP-2 was 1.338 ± 0.679. As compared to baseline value, the P value was statistically not significant in any of sequential values. In category-wise analysis, apart from statistically significant value in the 6th month in excellent category and good response category in the 1st month, all other values did not reveal any significant change in VEGF analysis. The analysis of TIMP-2 revealed a significant change in the levels from Sample 2 to Sample 6 in the excellent response group; however, the levels did not show a specific trend either increasing or decreasing. Conclusion: Despite its beneficial action in regression of hemangioma, the exact mechanism is yet to be identified. The exact duration of treatment needs further evaluation.
