Nail Infection/Removal

Therapy for Onychomycosis

In a randomized, double-blind study of 70 patients with onychomycosis of the finger and toenails. The results indicated topical treatment of onychomycosis with a combination of fluconazole 1% and urea 40% was more effective (82.8%) than fluconazole 1% nail lacquer (62.8%) alone in treatment of onychomycosis. Fluconazole was well tolerated and side effects were negligible.

Treatment of Fingernail Lichen Planus

Nail lichen planus most commonly occurs during the fifth and sixth decade of life and can be notoriously recalcitrant to many forms of treatment. Prevost and English of the University of Pittsburgh Department of Dermatology reported a case of successful treatment of destructive inflammatory lichen planus of the nails with combined topical therapy of tazarotene gel and clobetasol gel, without the occurrence of potential adverse affects of systemic treatments.

Although surgical excision is the most popular method for removing nails, the use of concentrated urea plasters applied under occlusion may be superior. The use of urea plasters has inherent advantages - they are inexpensive, several nails can be treated in one session, and the procedure is essentially painless. Various synergistic combinations and topical medications with penetrant enhancers can be compounded for antifungal therapy. Topical medications usually have a lower adverse drug-reaction profile than systemic medications.

Management of onychomycosis, a fungal infection of the fingernails and toenails, usually consists of systemic antifungal medications, topical therapy (e.g., urea ointment, desiccating solutions, keratolytics, vital dyes), or surgical intervention (e.g., nail plate avulsion, laser therapy). Topical prescription antifungal preparations, containing the active ingredient of your choice, may be less likely to cause the serious systemic side effects that can occur with oral antifungal therapy and can provide a more economical alternative, as lower doses are needed when the medication is applied topically at the site. Penetrant enhancers can be included in the preparation to improve the effectiveness of topical antifungals.
