# Amorolfine Nail Lacquer ## Overview Amorolfine is a morpholine-derivative antifungal agent used for the treatment of onychomycosis. It acts by inhibiting sterol synthesis in the fungal cell membrane, leading to the depletion of ergosterol and the accumulation of abnormal sterols, resulting in fungistatic and fungicidal activity. ## Primary Indications Treatment of distal and lateral subungual onychomycosis caused by dermatophytes, yeasts, and molds. ## Adult Dosing Apply to the affected fingernails or toenails once or twice weekly, according to local product labeling and severity. 1. File down the infected nail surface. 2. Clean the surface with the provided swab. 3. Apply the lacquer evenly over the entire surface of the infected nail. 4. Allow to dry for 3–5 minutes. ## Pediatric Dosing There is limited clinical data regarding safety and efficacy in children. Use is generally not recommended or should be guided by pediatric dermatology protocols based on the benefit-risk balance. ## Dose Adjustments No specific dosage adjustments are required for renal or hepatic impairment due to minimal systemic absorption. ## Contraindications Hypersensitivity to amorolfine or any component of the lacquer. ## Adverse Effects - Localized reactions: Erythema, pruritus, burning sensation, or blistering at the site of application. - Nail disorders: Discoloration, nail breakage, or brittle nails (often difficult to distinguish from the underlying fungal infection). ## Key Drug Interactions No clinically significant systemic drug-drug interactions have been reported due to negligible systemic absorption following topical application. Avoid concurrent use of other medicated nail products on the same nail. ## Monitoring - Monitor for the progression of nail regrowth. - Fingernails typically require 6 months of continuous treatment; toenails may require 9–12 months. - Discontinue if localized severe irritation or allergic dermatitis occurs. ## Clinical Pearls - **Treatment Duration:** Treatment must be continued until the infected nail is completely regenerated and the affected areas are cured. Stopping too early (e.g., when the nail looks visibly improved) often leads to relapse. - **Hygiene:** Use separate nail files for infected and healthy nails to prevent transmission. Do not reuse files for healthy nails. - **Cosmetics:** Do not apply artificial nails or cosmetic nail polish during treatment periods. - **Efficacy:** If the infection is extensive (e.g., affecting the nail matrix/lunula), topical therapy alone is unlikely to be curative, and oral systemic antifungals may be required. *** *Disclaimer: This information is for educational purposes only.
