Chemical avulsion with urea nail lacquer.
BACKGROUND
Among the therapeutic possibilities for onychomycosis, chemicalnail avulsion is a logical approach to the eradication of the pathogen.


METHODS
A new formulation was used as a nail lacquer containing 40% urea in a film-forming solution in 10 patients presenting with onychomycosis. The urea nail lacquer was applied with a brush twice a day for 1 week by the patient and for a further week in two patients presenting total dystrophic onychomycosis.


RESULTS
This transungual delivery system weakens the nail plate/nail bed attachment in the diseased area.


CONCLUSIONS
The urea nail lacquer is comfortable for the patient and allows easy removal of the affected part of the fungal nail plate.
