Which treatment involves a 4-6 week regimen for tinea pedis?

• A. Topical antifungal ointment
• B. Oral Terbinafine
• C. Intravenous antifungal
• D. Oral Fluconazole

Answer: (B)

Oral Terbinafine is regarded as a first-line treatment for tinea pedis, particularly in cases that are extensive, recurrent, or not adequately managed with topical therapies alone. The typical treatment duration for oral Terbinafine is indeed 4-6 weeks, which is effective in clearing the infection, particularly when it involves the deeper layers of the skin or when there is involvement of the toenails. Terbinafine works by inhibiting a specific enzyme required for fungal cell membrane synthesis, leading to the death of the fungus. This systemic therapy is particularly beneficial for patients with severe or persistent tinea pedis, as it ensures adequate drug levels are maintained throughout the body to efficiently tackle the infection. Topical antifungal ointments may require longer treatment periods and might not penetrate deeply enough for extensive cases. Intravenous antifungal therapies are reserved for more severe systemic fungal infections and are not indicated for localized infections like tinea pedis. Oral Fluconazole is also effective for certain types of fungal infections but is not the primary choice for tinea pedis, especially given that Terbinafine has proven to be more effective for dermatophyte infections like this one.
