Also Known As: Lamisil, Terbinafine hydrochloride, Terbinafine, Sebifin, Zimig
Terbinafine hydrochloride (Lamisil in Argentina, Australia, Belgium, Brazil, Canada, Chile, Egypt, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Mexico, Pakistan, New Zealand, Norway, Romania, Russia, Slovenia, South Africa, Sweden, United Kingdom, United States and Venezuela, also sold under the name Corbinal and Terbisil in Turkey) is a synthetic allylamine antifungal from Novartis. It is highly lipophilic in nature and tends to accumulate in skin, nails, and fatty tissues. As a generic it is sold under the name Zabel in Australia. It is also available as a generic medication in the United States, United Kingdom, Belgium, Switzerland and Brazil.
In India, Terbinafine hydrochloride is available in topical form under the brand name Sebifin (Ranbaxy Labs), Zimig (GSK Pharma) and mycoCeaze (ProgreÅ› Laboratories).
Terbinafine is mainly effective on the dermatophytes group of fungi.
As a 1% cream or powder it is used for superficial skin infections such as jock itch (Tinea cruris), athlete's foot (Tinea pedis) and other types of ringworm (Tinea corporis). Studies have shown that terbinafine cream works in about half the time required by other antifungals.
Oral 250 mg tablets are often prescribed for the treatment of onychomycosis of the toenail or fingernail due to the dermatophyte Tinea unguium. Fungal nail infections are located deep under the nail in the cuticle to which topically applied treatments are unable to penetrate in sufficient amounts. The tablets may, rarely, cause hepatotoxicity, so patients are warned of this and may be monitored with liver function tests. Alternatives to oral administration have been studied. In 2009, results from a clinical study of a new formulation (terbinafine in Transfersomes, referred to as TDT-067) for topical treatment of onychomycosis were reported by Celtic Pharma.
It has been found that terbinafine hydrochloride may induce or exacerbate subacute cutaneous lupus erythematosus. Persons with lupus erythematosus should first discuss possible risks with their doctor before initiation of therapy.
