Amorolfine, is a morpholine antifungal drug that inhibits Δ14-sterol reductase and cholestenol Δ-isomerase, which depletes ergosterol and causes ignosterol to accumulate in the fungal cytoplasmic cell membranes. Sold under the brand name Loceryl among others, amorolfine is commonly available in the form of a nail lacquer, containing 5% amorolfine hydrochloride as the active ingredient. It is used to treat onychomycosis. Amorolfine 5% nail lacquer in once-weekly or twice-weekly applications was shown in two decades-old studies to be between 60% and 71% effective in treating toenail onychomycosis; complete cure rates three months after stopping treatment were 38% and 46%. However, full experimental details of these trials were not available, and since they were first reported in 1992 there have been no subsequent trials.
