What’s the Treatment for a Fungal Nail Infection?

Treatment for Fungal Nail Infection

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. The treatment of onychomycosis involves various options, including oral and topical antifungal agents, as well as combination therapies. Oral treatments like fluconazole, itraconazole, and terbinafine have shown high efficacy but may be associated with systemic side effects. Topical treatments, including butenafine, terbinafine solution, efinaconazole, and tavaborole, offer effective alternatives with fewer systemic risks. Combination therapies and novel treatments like acidifying nail polish also provide promising results. The choice of treatment should be based on the severity of the infection, patient preference, and potential side effects.

Fungal nail infections, or onychomycosis, are common conditions that affect the toenails and fingernails. These infections are primarily caused by dermatophytes, but can also be due to non-dermatophyte molds and yeasts. The infection can lead to nail discoloration, thickening, and separation from the nail bed, causing discomfort and potentially impacting the quality of life. Various treatment options are available, ranging from topical and oral antifungal medications to combination therapies. This article reviews the efficacy and safety of different treatment modalities for onychomycosis.

Oral Antifungal Treatments

Fluconazole

Fluconazole is an oral antifungal agent that has shown significant efficacy in treating onychomycosis. A study comparing different doses of fluconazole (150, 300, and 450 mg) administered once weekly demonstrated high clinical success rates (86% to 89%) and mycologic eradication rates (47% to 62%) at the end of therapy. The treatment was well tolerated, with a low relapse rate of 4% over a 6-month follow-up period1. Another study confirmed the effectiveness of fluconazole for fingernail onychomycosis, with clinical cure rates ranging from 76% to 90% and mycologic eradication rates of 89% to 100%6.

Itraconazole and Terbinafine

Itraconazole and terbinafine are other oral antifungal agents used in the treatment of onychomycosis. A clinical study evaluated the effectiveness of various treatment protocols, including fluconazole, itraconazole (both continual and pulse therapy), and terbinafine. The cure rates for these treatments ranged from 75% to 100%, with no significant difference in efficacy among the different protocols10.

Topical Antifungal Treatments

Butenafine and Urea

Topical treatments are often preferred due to their lower risk of systemic side effects. A study investigating the combination of 2% butenafine hydrochloride and 20% urea cream showed a significant improvement in 73.3% of patients, with an 88% cure rate compared to 0% in the placebo group. The treatment was well tolerated, with no drug-related adverse symptoms reported by 91.6% of patients2.

Terbinafine Solution (MOB-015)

Topical terbinafine 10% solution (MOB-015) was evaluated in a phase III study for the treatment of distal and lateral subungual onychomycosis. The mycological cure rate was 69.9%, and the complete cure rate was 4.5%, significantly higher than the vehicle group. The treatment was well tolerated, with a similar adverse event profile to the vehicle3.

Efinaconazole

Efinaconazole 10% solution, a topical triazole antifungal, was tested in two phase III studies. The mycologic cure rates were 55.2% and 53.4%, and the complete cure rates were 17.8% and 15.2%, significantly higher than the vehicle. The treatment was associated with minimal local site reactions5.

Tavaborole

Tavaborole topical solution, 5%, demonstrated efficacy in two phase III trials, with mycologic cure rates of 31.1% to 35.9% and complete cure rates of 6.5% to 9.1%. The treatment was well tolerated, with application-site reactions being the most common adverse events8.

Combination and Alternative Treatments

Butenafine and Tea Tree Oil

A combination of 2% butenafine hydrochloride and 5% Melaleuca alternifolia (tea tree) oil in a cream was tested in a randomized, double-blind study. The treatment resulted in an 80% cure rate, with no relapses reported during follow-up. Mild inflammation was the only reported adverse effect7.

Acidifying Nail Polish

A prospective, randomized trial compared a daily application of an aqueous, acidifying, peelable nail polish to weekly amorolfine application. Both treatments showed comparable increases in the percentage of healthy nail surface, with significant improvements in onychomycosis-related parameters and no significant side effects9.
