Does Terbinafine inhibit ergosterol?
Terbinafine, an allylamine antifungal, inhibits biosynthesis of ergosterol, an essential component of fungal cell membrane, via inhibition of squalene epoxidase enzyme.

Is terbinafine a monoamine oxidase inhibitor?
In vivo studies have shown that Terbinafine is an inhibitor of the CYP450 2D6 isozyme. Drugs predominantly metabolized by the CYP450 2D6 isozyme include the following drug classes: tricyclic antidepressants, selective serotonin reuptake inhibitors, beta-blockers, antiarrhythmics class 1C (e.g., flecainide and propafenone) and monoamine oxidase inhibitors Type B. Coadministration of Terbinafine tablets should be done with careful monitoring and may require a reduction in dose of the 2D6-metabolized drug. In a study to assess the effects of Terbinafine on desipramine in healthy volunteers characterized as normal metabolizers, the administration of Terbinafine resulted in a 2-fold increase in C max and a 5-fold increase in area under the curve (AUC). In this study, these effects were shown to persist at the last observation at 4 weeks after discontinuation of Terbinafine tablets. In studies in healthy subjects characterized as extensive metabolizers of dextromethorphan (antitussive drug and CYP2D6 probe substrate), Terbinafine increases the dextromethorphan/ dextrorphan metabolite ratio in urine by 16-to 97-fold on average. Thus, Terbinafine may convert extensive CYP2D6 metabolizers to poor metabolizer status.
