4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Onychomycoses caused by dermatophytes, yeasts and moulds without nail matrix involvement.
4.2 Posology and method of administration
Posology
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:
1. Before the first application of Amorolfine 5% w/v Medicated 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 an alcohol cleaning pad. Before repeat application of Amorolfine 5% w/v Medicated 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.
2. With one of the reusable applicators supplied, apply the nail lacquer to the entire surface of the affected nails. Allow the nail lacquer to dry for 3-5 minutes. 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 5% w/v Medicated 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.
Older people
There are no specific dosage recommendations for use in older people.
Paediatric population
Amorolfine 5% w/v Medicated Nail Lacquer is not recommended for use in children due to a lack of data on safety or efficacy.
Method of Administration
Cutaneous use.
4.3 Contraindications
Amorolfine 5% w/v Medicated Nail Lacquer must not be reused by patients who have shown hypersensitivity to the treatment.
Hypersensitivity to the active substance amorolfine or to any of the excipients.
4.4 Special warnings and precautions for use
Avoid contact of the lacquer with eyes, ears and mucous membranes.
Patients with underlying conditions predisposing to fungal nail infections should discuss appropriate treatment with a doctor. Such conditions include peripheral circulatory disorders, diabetes mellitus, and immunosuppression.
Patients with nail dystrophy and destroyed nail plate should discuss appropriate treatment with a doctor.
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.
4.5 Interaction with other medicinal products and other forms of interaction
There are no specific studies involving concomitant treatment with other topical medicines.
4.6 Fertility, pregnancy and lactation
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.
4.7 Effects on ability to drive and use machines
Amorolfine 5% w/v Medicated Nail Lacquer has no influence on the ability to drive and use machines.
4.8 Undesirable effects
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.

5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antifungals for dermatological use, other antifungals for topical use ATC code: D01AE16
Amorolfine 5% w/v Medicated Nail Lacquer is a topical antifungal which contains the active ingredient amorolfine.
Its fungistatic and fungicidal efficacy 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. Amorolfine is a broad spectrum antimycotic. It is highly active against the current or casual agents of onychomycoses:
- The yeasts:
* Candida albicans and other species of Candida.
- The dermatophytes:
* Trichophyton rubrum, Trichophyton interdigitale and Trichophyton mentagrophytes, and other species of Trichophyton,
* Epidermophyton floccosum,
* Microsporum.
- The moulds:
* Scopulariopsi.
- The slightly sensitive moulds:
* Aspergillus, Fusarium, Mucorale
- The dematiacea (black fungus):
* Hendersonula, Alternaria, Cladospirum.
5.2 Pharmacokinetic properties
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 5% w/v Medicated Nail Lacquer, there is no indication of drug accumulation in the body.
5.3 Preclinical safety data
There are no findings of relevance to the prescriber other than those mentioned elsewhere in the SPC.
