Terbinafine hydrochloride.
Description
Colorless, transparent solution.
Each 30 g of solution contains: Drug substance: Terbinafine hydrochloride 0.3 g.
Excipients/Inactive Ingredients: Cetomacrogol 1000 (Eumulgin B2), propylene glycol, ethanol 96%, anhydrous citric acid, purified water.
Action
Pharmacotherapeutic group: Antifungal for topical use. ATC code: D01AE15.
Pharmacology: Pharmacodynamics: Terbinafine is an allylamine, which has a broad spectrum of antifungal activity in fungal infections of the skin caused by dermatophytes such as Trichophyton (e.g. T. rubrum, T. mentagrophytes, T. verrucosum, T. violaceum), Microsporum canis and Epidermophyton floccosum. At low concentrations terbinafine is fungicidal against dermatophytes and moulds. The activity against yeasts is fungicidal (e.g. Pityrosporum orbiculare or Malassezia furfur) or fungistatic, depending on the species.
Terbinafine interferes specifically with fungal sterol biosynthesis at an early step. This leads to a deficiency in ergosterol and to an intracellular accumulation of squalene, resulting in fungal cell death. Terbinafine acts by inhibition of squalene epoxidase in the fungal cell membrane. The enzyme squalene epoxidase is not linked to the cytochrome P450 system. Terbinafine does not influence the metabolism of hormones or other drugs.
Pharmacokinetics: Less than 5% of the dose is absorbed after topical application to humans; systemic exposure is thus very slight.
Indications/Uses
The treatment of tinea pedis (athlete's foot) and tinea cruris (dhobie (jock) itch) caused by Trichophyton (e.g. T. rubrum, T. mentagrophytes, T. verrucosum, T. violaceum) and Epidermophyton floccosum.
Dosage/Direction for Use
Method of Administration: For cutaneous use.
Cleanse and dry the affected areas thoroughly before applying the medication from a distance of 5 to 10 cm. A sufficient amount of spray solution should be applied to wet the treatment area(s) thoroughly, and to cover the affected skin and surrounding area.
Posology of administration: Adults: Use once daily, for one week.
Duration and frequency of treatment: Interdigital type tinea pedis, and tinea cruris: Once a day for one week.
Relief of clinical symptoms usually occurs within a few days. Irregular use or premature discontinuation of treatment carries the risk of recurrence. If there are no signs of improvement after two weeks, a physician should be consulted.
Dosing in special populations: Paediatric population: Not to be used in children under 16 years of age. Experience with the use and efficacy of terbinafine hydrochloride in children is limited and its use cannot, therefore, be recommended.
Elderly patients: There is no evidence to suggest that elderly patients require different dosages or experience side effects different from those in younger patients.
Overdosage
Symptoms: The low systemic absorption of topical terbinafine renders overdosage extremely unlikely.
Accidental ingestion of the contents of one 30 ml bottle containing 300 mg terbinafine hydrochloride, is comparable to ingestion of one tablet containing 250 mg of terbinafine hydrochloride (adult oral unit dose).
Should a larger amount of terbinafine be inadvertently ingested, adverse effects similar to those observed with an overdosage of terbinafine tablets are to be expected. These include headache, nausea, epigastric pain and dizziness.
In case of accidental oral ingestion, the ethanol content has to be considered. The drug contains 30.56% w/w ethanol.
Treatment of overdose: If an overdose occurs, terbinafine hydrochloride should be eliminated by the administration of activated charcoal, and giving symptomatic supportive therapy if needed. Accidentally ingested, the recommended treatment of overdosage consists of eliminating the active substance, primarily by the administration of activated charcoal, and giving symptomatic supportive therapy if needed.
Contraindications
Patients with hypersensitivity to terbinafine hydrochloride or to any ingredient of the drug.
Special Precautions
Use with caution in patients with lesions where ethanol could be irritating.
For external use only. It may be irritating to the eyes. Do not be used on the face.
In case of accidental contact with the eyes, rinse eyes thoroughly with running water.
Avoid inhalation. In case of accidental inhalation, consult a physician if any symptoms develop or persist.
The drug contains ethanol 275 mg/g which can cause burning sensation on damaged skin.
The drug contains propylene glycol 600 mg/g which may cause skin irritation.
Effects on Ability to Drive and Use Machines: There is no evidence of the effect of the drug on the ability to drive and use machines.
Use In Pregnancy & Lactation
Pregnancy: Animal studies did not reveal any teratogenic or embryofoetotoxic potential of terbinafine hydrochloride.
No cases of malformations in humans have been reported with the use of the drug. There is limited clinical experience in pregnant women. Foetal toxicity studies in animals suggest no adverse effects.
Terbinafine hydrochloride topical solution should not be used during pregnancy unless clearly necessary.
Breast-feeding: Terbinafine hydrochloride is excreted in breast milk. Therefore, mothers should not use the drug during the period of breast-feeding. Infants must not be allowed to come into contact with any treated skin, including the breast.
Fertility: No effect of terbinafine hydrochloride on fertility has been seen in animal studies.
Adverse Reactions
Local symptoms such as pruritus, skin exfoliation, application site pain, application site irritation, pigmentation disorder, skin burning sensation, erythema and scab may occur at the site of application.
These minor symptoms must be distinguished from hypersensitivity reactions such as widespread pruritus, rash, bullous eruptions and hives, which are reported in sporadic cases and require discontinuation.
In case of accidental contact with the eyes terbinafine hydrochloride may be irritating to the eyes. In rare cases the underlying fungal infection may be aggravated.
Adverse reactions are listed as follows by system organ class and frequency. Frequencies are defined as: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), or not known (cannot be estimated from available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.
Immune system disorders: Not known: Hypersensitivity.
Eye disorders: Rare: Eye irritation.
Skin and subcutaneous tissue disorders: Common: Skin exfoliation, pruritus.
Uncommon: Skin lesion, scab, skin disorder, pigmentation disorder, erythema, skin burning sensation.
Rare: Dry skin, dermatitis contact, eczema.
Not known: Rash.
General disorders and administration site conditions: Uncommon: Pain, application site pain, application site irritation.
Rare: Condition aggravated.
Any adverse drug reactions should be immediately reported to the physician or pharmacist.
