Treatment of cutaneous sporotrichosis with terbinafine

Terbinafine, an allylamine antifungal agent, has been shown to have excellent in-vitro activity against dermatophytes. Several other fungi of importance also show in-vitro sensitivity. Because terbinafine is fungicidal rather than fungistatic in action, its efficacy in treating such fungal infections requires evaluation. Five patients with cutaneous sporotrichosis were treated with 250 mg of terbinafine twice daily. All of the patients were cured. Overall, the clinical response was rapid. In three patients, negative culture was achieved within 8 weeks; in the other two, negative culture was obtained at 12 and 32 weeks, respectively. Terbinafine was well tolerated, although one patient developed erectile dysfunction while receiving treatment. This was completely resolved on stopping the treatment. The treatment of sporotrichosis is also reviewed in this article.
