title: Itraconazole and terbinafine in perspective. From petri dish to patient.
abstract: This paper compares the antifungal activity and efficacy of itraconazole and terbinafine in vitro with their experimental activity and efficacy in vivo in patients with superficial fungal infections (tinea pedis and onychomycosis). Onychomycosis and tinea pedis are often treated with oral antifungals. With the introduction of newer agents, such as terbinafine and itraconazole, efficacy and safety have been improved. In vitro evaluation showed somewhat better results for terbinafine over itraconazole against dermatophytes, but in vivo results were at least equivalent. Moreover, according to ex vivo studies, itraconazole is a broad-spectrum agent with higher cure rates than terbinafine for fungal infections other than dermatophytosis (e.g., Candida infections). A meta-analysis of data from all published clinical trials comparing the efficacy and safety of terbinafine and itraconazole revealed similar high cure rates (> 70%) for both antifungal agents and similar adverse-event profiles. Both treatments were safe and well tolerated. Antifungal research has responded to the challenges of treating superficial infections by developing effective, well-tolerated, fast-acting antifungal therapies. The reduction in treatment duration also has led to improved patient compliance. The most notable difference between itraconazole and terbinafine is the 1-week pulse regimen available with itraconazole as opposed to the continuous treatment course available for terbinafine.
