Using topical phenytoin to treat recalcitrant neuropathic diabetic foot ulcers may improve wound healing according to a small scale study published in the Journal of Wound Care.
The study involved 32 patients, who were treated once a day for eight weeks, with a topical phenytoin in the form of a 2% aerosol powder along with their usual diabetes treatment.
The researchers found that 25% of patients achieved a 50% reduction in the size of the ulcer after 8 weeks. The treatment did not eradicate bacteria isolated found in the wounds.
The authors recommend further research to find out which patients are most likely to respond to treatment.
