Oral
terbinafine (
Lamisil, Novartis Pharma AG, Basel, Switzerland) is an effective
therapy for
fungal infections of the skin and nails. A post-marketing surveillance study was undertaken to evaluate the clinical efficacy and safety of oral
terbinafine. A total of 454 patients with clinically and mycologically confirmed superficial
fungal infections of the skin were enrolled from 79 dermatology clinics. Patients received oral
terbinafine (250 mg day-1) for 2 weeks. Specific signs and symptoms were assessed by standard questionnaire before, immediately after, and 4 weeks
after treatment. Observed improvements in patients after 2 weeks treatment were:
erythema 81%, blistering 33%, exudation 50%, scaling 89%,
pruritus 83%. After 4 weeks treatment,
erythema was absent in 85% of patients, blistering and exudation in 99.7%, scaling in 82%, and
pruritus in 94%. Overall clinical efficacy was assessed as good to excellent in 97% of patients. Adverse effects--mainly gastrointestinal and minor skin rashes--were reported in 5.3% of patients. The results of this study confirm that oral
terbinafine is safe and highly effective for the short-term treatment of fungal skin
infections.
