    Abstract:
    OBJECTIVE: To evaluate and compare two strengths of topical phenytoin sodium suspension (2% and 4%) with normal saline in the healing of acute trophic ulcers in leprosy patients. METHODS: A prospective, parallel, double-blind, randomized study was conducted in 45 leprosy inpatients with acute trophic ulcers. Patients were randomized to receive 2%, 4% or normal saline dressing on their ulcers once daily for 4 weeks. Efficacy parameters such as a reduction in the surface area of the ulcer, bacterial culture of the ulcer swab, appearance of healthy granulation tissue, cessation of ulcer discharge and overall gradation of clinical healing and safety were assessed at weekly intervals. RESULTS: The ulcer area reduction was greater in the 2% and 4% phenytoin groups compared with the normal saline group (p<0.001). Appearance of healthy granulation tissue and cessation of ulcer discharge was also observed earlier in the two phenytoin groups. At the end of 4 weeks, 11 ulcers each had healed completely in both the 2% and 4% phenytoin groups compared with none in the control group. There were no statistical differences between the 2% and 4% phenytoin groups. No side effects were reported by any patient. CONCLUSION: Topical phenytoin appears to be an effective, safe and cheap therapeutic option for the healing of trophic ulcers in leprosy patients.
