Study evaluates these take of diclofenac sodium when used in conjunction with miconazole and urea as a topical antifungal nail gel treatment for onychomycosis. All of the patient's will be treated with the active formula and blood levels of diclofenac sodium tested for as well as monitoring of hepatic and renal functions

Tinea Unguium/onychomycosis is a ubiquitous health problem affecting ~3% of the adult population. It is associated with higher risk for other disease processes. Effective treatment for this disease has been lacking. Oral antifungal agents are associated with high incidence of recurrence of disease, hepatotoxicity, cytochrome P450 Pathway interference, non-compliance, side effects and cost. No effective long-term topical applications have been verified. Debridement of the damaged nail in combination with a broad-spectrum topical antifungal agent and an anti-inflammatory agent is a safe, inexpensive and easily formulated alternative to previous ineffective treatments. The rationale for debridement is simple in that the effectiveness of the topical antifungal is present only when it is in contact with the fungal agent, nail bed and involved diseased tissue. The associated inflammatory response associated with fungal infections is well-established. The only topical NSAID available in the United States is diclofenac sodium. The combination of miconazole, diclofenac sodium and urea has proven effective in this researcher's self-treatment of tinea unguium. Miconazole and diclofenac sodium are well studied and well-established pharmaceutical
