OBJECTIVE To review onychomycosis with an emphasis on the traditional
and newer antifungal agents available to treat onychomycosis. QUALITY
OF EVIDENCE We searched MEDLINE for the years 1966 to 1995. We exclude
d case reports from our analysis. MAIN FINDINGS For treating onychomyc
osis, newer antifungal agents (such as terbinafine, itraconazole, and
fluconazole) are more cost-effective than the traditional agents grise
ofulvin and ketoconazole. Of the newer agents, only terbinafine is cur
rently approved in Canada for treating onychomycosis. CONCLUSIONS The
new generation of drugs is an important addition to the armamentarium
of therapies available for treating onychomycosis. At the moment, in C
anada, terbinafine is the drug of choice and more cost-effective than
griseofulvin for treating dermatophyte-induced onychomycosis.
