'''Terbinafine hydrochloride''' ('''Lamisil''' in UK, US, France, Canada, Romania and Hungary, also sold under the name '''Terbisil''') is a synthetic [[allylamine]] [[antifungal]]. It is highly [[lipophilic]] in nature and tends to accumulate in skin, [[Nail (anatomy)|nails]], and fatty tissues.  As a generic it is sold under the name '''Zabel''' in Australia. It is now also available as a generic in the U.S.
==Pharmacology==
Terbinafine [[hydrochloride]] is a white fine crystalline powder that is freely soluble in [[methanol]] and [[methylene chloride]], soluble in [[ethanol]], and slightly soluble in water. 
Like other allylamines, terbinafine inhibits [[ergosterol]] synthesis by inhibiting [[squalene epoxidase]], an enzyme that is part of the fungal [[cell wall]] synthesis pathway.
==Indications==
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]]. 
Oral 250mg 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]]. Alcohol consumption should also be avoided while taking terbinafine.
===Specific US issues===
Many health insurance companies consider these infections to be a cosmetic problem, and either do not cover the cost of the months-long course of Lamisil, which can run into the thousands of dollars, or recommend use of less expensive alternatives like [[fluconazole]].
'''FDA approval'''
The FDA has approved the first generic versions of prescription Lamisil (terbinafine hydrochloride) tablets.  The remaining patent or exclusivity for Lamisil expired on [[June 30]], [[2007]].
On [[September 28]], [[2007]], the [[U.S.]] [[Food and Drug Administration]] stated that Lamisil (terbinafine hydrochloride, by [[Novartis AG]]) is a new [[treatment]] approved for use by [[children]] aged 4 up. The [[antifungal]] [[granules]] that can be sprinkled on a child's food to treat [[ringworm]] of the scalp, [[Tinea capitis]]. <ref>[http://www.reuters.com/article/governmentFilingsNews/idUSN2820532120070928  Reuters, US FDA approves oral granules for scalp ringworm]</ref>
