Treatment of tinea capitis.
OBJECTIVE
To review the epidemiology, pathogenesis, mycology, clinical presentation, and pharmacotherapy of tinea capitis, and describe the role of newer antimycotic agents.


METHODS
A MEDLINE search restricted to English-language articles published from 1966 through 1996 and journal references were used in preparing this review.


METHODS
The data on mycology, pharmacokinetics, adverse effects, and drug interactions were obtained from controlled studies and case reports appearing in the literature. Both open-label and comparative studies were evaluated to assess the efficacy of antimycotics in the treatment of this infection.


RESULTS
Griseofulvin is the drug of choice in the treatment of tinea capitis. Newer agents with greater efficacy or shorter treatment durations continue to be explored. Ketoconazole, the first azole studied for efficacy in tinea capitis, has not demonstrated any clinical advantage over griseofulvin in several controlled clinical trials. Itraconazole is effective, but the available data are limited to case reports and a single uncontrolled study. Terbinafine similarly has shown promise in the treatment of tinea capitis, but the oral formulation was only recently approved in the US. Existing studies reflect the results in infection with pathogens not seen in the US. Both itraconazole and terbinafine achieve high concentrations in the hair and stratum corneum that persist for several weeks following drug administration. This may enable shorter courses of therapy; however, comparative studies need to be conducted in the US.


CONCLUSIONS
Tinea capitis remains the most common dermatophyte infection in young urban children. Oral antifungal therapy is required for effective treatment, often for several months. The combination of griseofulvin with a selenium sulfide shampoo continues to be the mainstay of therapy until more experience is gained with the newer antimycotics.
