Scientific production on the applicability of phenytoin in wound healing

Phenytoin is an anticonvulsant that has been used in wound healing. The objectives of this study were to describe how the scientific production presents the use of phenytoin as a healing agent and to discuss its applicability in wounds. A literature review and hierarchy analysis of evidence-based practices was performed. Eighteen articles were analyzed that tested the intervention in wounds such as leprosy ulcers, leg ulcers, diabetic foot ulcers, pressure ulcers, trophic ulcers, war wounds, burns, preparation of recipient graft area, radiodermatitis and post-extraction of melanocytic nevi. Systemic use of phenytoin in the treatment of fistulas and the hypothesis of topical use in the treatment of vitiligo were found. In conclusion, topical use of phenytoin is scientifically evidenced. However robust research is needed that supports a protocol for the use of phenytoin as another option of a healing agent in clinical practice.
