Amorolfine Hydrochloride Ph.Eur. equivalent to Amorolfine 50 mg, Absolute Alcohol 63.5% v/v, Base q.s.
Excipients/Inactive Ingredients: Absolute Alcohol (Ethanol 99% v/v), N-butyl Acetate Extra Pure, Ethyl Acetate, Ammonio Methacrylate Copolymer (Type A), Triacetin.
Pharmacotherapeutic group: Other antifungals for topical use. ATC code: D01AE16.
Pharmacology: Pharmacodynamics: Mechanism of action: Amorolfine nail lacquer is a topical antimycotic. Amorolfine belongs to a new chemical class, and its fungicidal action is based on an alteration of the fungal cell membrane targeted primarily on sterol biosynthesis. The ergosterol content is reduced, and at the same time unusual sterically nonplanar sterols accumulate.
Pharmacokinetics: Amorolfine from nail lacquer penetrates into and diffuses through the nail plate and is thus able to eradicate poorly accessible fungi in the nail bed. Systemic absorption of the active ingredient is very low with this type of application.
Following prolonged use of Amorolfine Nail Lacquer, there is no indication of drug accumulation in the body.
Toxicology: Preclinical safety data: None stated.
Microbiology: Amorolfine is a broad spectrum antimycotic. It is highly active (MIC <2 mcg/mL) in vitro against yeasts: Candida, Cryptococcus, Malassezia; dermatophytes: Trichophyton, Microsporum, Epidermophyton; moulds: Hendersonula, Altemaria, Scopulariopsis; dematiacea: Cladosporium, Fonsecaea, Wangiella; dimorphic fungi: Coccidioides, Histoplasma, Sporothrix.
With the exception of Actinomyces, bacteria are not sensitive to amorolfine. Propionibacterium acnes is only slightly sensitive.
Onychomycoses caused by dermatophytes, yeasts and moulds.
The nail lacquer should be applied to the affected finger or toe nails once weekly. Twice weekly application may prove beneficial in some cases.
The patient should apply the nail lacquer as follows: Before the first application of Amorolfine Nail Lacquer, it is essential that the affected areas of nail (particularly the nail surfaces) should be filed down as thoroughly as possible using the nail file supplied. The surface of the nail should then be cleansed and degreased using a cleaning pad (as supplied). Before repeat application of Amorolfine Nail Lacquer, the affected nails should be filed down again as required, following cleansing with a cleaning pad to remove any remaining lacquer.
Caution: Nail files used for affected nails must not be used for healthy nails.
With one of the reusable applicators supplied, apply the nail lacquer to the entire surface of the affected nails and allow it to dry. After use, clean the applicator with the same cleaning pad used before for nail cleaning. Keep the bottle tightly closed.
For each nail to be treated, dip the applicator into the nail lacquer without wiping off any of the lacquer on the bottle neck.
Caution: When working with organic solvents (thinners, white spirit, etc.) wear impermeable gloves in order to protect the Amorolfine Nail Lacquer on the nails.
Treatment should be continued without interruption until the nail is regenerated and the affected areas are finally cured. The required frequency and duration of treatment depends essentially on intensity and localisation of the infection. In general, it is six months (finger nails) and nine to twelve months (toe nails). A review of the treatment is recommended at intervals of approximately three months.
Co-existent tinea pedis should be treated with an appropriate antimycotic cream.
Elderly: There are no specific dosage recommendations for use in elderly patients.
Paediatric population: There are no specific dosage recommendations for children owing to the lack of clinical experience available to date.
No systemic signs of overdose are expected following topical application of amorolfine 5% nail lacquer.
In case of accidental oral ingestion, appropriate symptomatic measures should be taken if needed.
Hypersensitivity to the active substance or to any of the excipients listed in Description.
Avoid contact of the lacquer with eyes, ears and mucous membranes.
Owing to the lack of clinical experience available to date, children should not be treated with amorolfine 5% nail lacquer.
During the application of amorolfine no cosmetic nail lacquer or artificial nails shall be used.
When organic solvents are used impermeable gloves shall be used otherwise amorolfine nail lacquer will be removed.
Effects on ability to drive and use machines: Not relevant.
Experience with amorolfine use during pregnancy and/or lactation is limited. Only a few cases of exposure to topical amorolfine use in pregnant women have been reported in the post-authorisation setting, therefore the potential risk is unknown. Studies in animals have shown reproductive toxicity at high oral doses; it is unknown whether amorolfine is excreted in human milk. Amorolfine should not be used during pregnancy and/or lactation unless clearly necessary.
Adverse drug reactions are rare. Nail disorders (e.g. nail discoloration, broken nails, brittle nails) may occur. These reactions can also be linked to the onychomycosis itself. (See table.)
