Objective: The aim of this meta-analysis was to evaluate the efficacy of topical phenytoin in the treatment of ulcers of different origin compared with other standard topical treatment. Methods: Randomized controlled trials were identified by searching PubMed, Embase, Medline, and Web of Science. Outcomes were complete wound healing rate and reduction in wound volume or surface area. Results: Thirteen studies with 980 patients were included. Topical phenytoin were associated with a statistically significant improvement of complete wound healing rate compared with other line of management in 11 randomized control trial of 815 patients (odds ratio = 3.03, 95% confidence interval 2.23-4.10, Z = 7.14, P < 0.00001). No publication bias exists in this meta-analysis. Three studies from India also confirmed that the topical phenytoin was associated with a statistically significant percent reduction in wound volume compared with the other dressing (mean difference 23.56, 95% confidence interval 19.48-27.64, Z = 11.32, P < 0.00001). Conclusion: The existent evidence shows that topical phenytoin is more effective for ulcer treatment. |
