Topical phenytoin improves wound healing with analgesic and antibacterial properties and minimal side effects: a systematic review

CONCLUSION: Phenytoin enhances wound healing and offers analgesic and antibacterial properties with minimal adverse effects. Further research is needed on optimal dosage of phenytoin, as well as frequency, delivery vehicles, and effects on other postoperative wounds.BACKGROUND: Although phenytoin's potential benefits in wound healing, pain relief, and infection control across various wound types have been previously reported, its use in wound care remains limited.OBJECTIVE: To conduct a comprehensive review to assess the efficacy of topical phenytoin compared with standard and alternative treatments for different wound types.MATERIALS AND METHODS: The authors last searched Cochrane Library, PubMed, PubMed Central, and MEDLINE in June 2023. All English-language human RCTs and NRCTs from any time were included. The RoB 2 was used to assess quality of randomized trials, and the ROBINS-I was used to assess the quality of nonrandomized trials. Studies with a low risk of bias or some concerns in no more than 1 domain were included. Data collected and analyzed included wound type, interventions, sample size, outcome measures, and adverse effects.RESULTS: The search yielded 101 studies, of which 17 RCTs and 8 NRCTs were eligible for inclusion. Of the included studies, 56% had a low risk of bias in all domains. The sample sizes varied between 20 and 130 (median, 60), with a total sample size of 1653 patients. Phenytoin improved wound healing in 17 of the 24 studies that evaluated it (...
