Loceryl Nail Lacquer contains Amorolfine 5% w/v, an antifungal agent indicated for the topical treatment of onychomycosis caused by dermatophytes, yeasts, and molds. Amorolfine belongs to the morpholine class and acts by inhibiting fungal sterol biosynthesis, leading to disruption of the fungal cell membrane and subsequent fungal cell death. This lacquer is applied directly to the affected nails once or twice weekly, allowing the active ingredient to penetrate the nail plate and exert its antifungal effect. Loceryl is suitable for mild to moderate fungal infections involving the fingernails or toenails and is particularly effective in cases where systemic therapy is contraindicated or not preferred. Treatment duration varies depending on the severity and location of the infection, typically ranging from six months for fingernails to up to twelve months for toenails, with regular monitoring recommended to assess therapeutic response. The lacquer dries quickly, forming a film that facilitates sustained drug release. Common adverse effects are usually mild and may include local irritation, redness, or itching at the application site. Loceryl Nail Lacquer should be used with caution in patients with known hypersensitivity to amorolfine or any lacquer components. It is not intended for use on skin or mucous membranes.
