We studied the in vitro antifungal activity profile of amorolfine (AMR), bifonazole (BFZ), clotrimazole (CLZ), econazole (ECZ), fluconazole (FNZ), itraconazole (ITZ), ketoconazole (KTZ), miconazole (MNZ), oxiconazole (OXZ), tioconazole (TCZ) and terbinafine (TRB) against 26 clinical isolates of Scopulariopsis brevicaulis from patients with onychomycosis by means of an standardized microdilution method. Although this opportunistic filamentous fungi was reported as resistant to several broad-spectrum antifungals agents, obtained data shows a better fungistatic in vitro activity of AMR, OXZ and TRB (0.08, 0.3, and 0.35 mg/L, respectively) in comparison to that of CLZ (0.47 mg/L), ECZ (1.48 mg/L), MNZ (1.56 mg/L, BFZ (2.8 mg/L), TCZ (3.33 mg/L), KTZ (3.73 mg/L). FNZ (178.47 mg/L) and ITZ (4.7 mg/L) showed a reduced in vitro antifungal activity against S. brevicaulis. Obtained MICs show the low in vitro antifungal susceptibility of S. brevicaulis to topical drugs for onychomycosis management, with exceptions (AMR, OZX and TRB).
