Abstract
Terbinafine (Lamisil) is a new antifungal drug which is now available in many countries worldwide. This review seeks to summarize why terbinafine is of interest and how well it reaches its target sites--the stratum corneum and nail plate. The diseases in which it is potentially effective are described and evidence that terbinafine is of value in these diseases is cited. There are very few effective drugs which do not have some potential for producing side-effects and these are discussed.
