Terbinafine (brand name Lamisil, Terbisil, Terboderm and others) is an antifungal medication used to treat ringworm and fungal nail infections. Terbinafine inhibits ergosterol synthesis by inhibiting squalene epoxidase, an enzyme that is part of the fungal cell membrane synthesis pathway. Because terbinafine prevents the conversion of squalene to lanosterol, ergosterol cannot be synthesized. This is thought to change cell membrane permeability, causing fungal cell lysis. Many side effects and adverse drug reactions have been reported with oral terbinafine hydrochloride possibly due to its extensive biodistribution and the often extended durations involved in antifungal treatment (longer than two months).

TRB (Terbinafine) were diluted 100-fold in dimethyl sulfoxide to obtain stock solutions that were kept at -20ºC. The antifungals were diluted in RPMI-1640 medium (Sigma Chemical Co, Missouri, USA) at pH 7.0 buffered with 0.16 M morpholinepropanesulfonic acid to obtain final concentrations ranging from 0.03-16 μg/mL for TRB. The diluted antifungal suspensions were then added to 96-well microtitre trays. Next, each fungal suspension was inoculated into the appropriate well at final concentrations ranging from 0.5 x 10^3-2.5 x 10^3 CFU/mL. The minimum inhibitory concentration (MIC) of each antifungal was determined by spectrophotometric reading at 492 nm following incubation at 35ºC for 72 h.
