• 外観

  白色～うすい黄色粉末～結晶

• 効能

  抗真菌薬, エルゴステロール合成阻害薬

• 使用

  Terbinafine (Lamisil) is a second-generation allylamine that is related to naftifine; however, it is 10 to 100 times more potent in vitro. It is fungicidal, whereas griseofulvin, ketoconazole, itraconazole, and other azole derivatives are all fungistatic. Because it is fungicidal, duration of therapy is shorter, and relapse rates are less than with other oral or topical therapies. Terbinafine acts by inhibiting squalene epoxidase and thereby decreasing synthesis of ergosterol, an essential component of fungal cell membranes. It is highly lipophilic and concentrates in the stratum corneum, sebum, and hair follicles. Slightly better cure rates are attained with b.i.d. than with daily dosing.

• 定義

  ChEBI: A tertiary amine that is N-methyl-1-naphthalenemethylamine in which the amino hydrogen is replaced by a 3-(tertbutylethynyl)allyl group. An antifungal agent administered orally (generally as the hydrochloride salt) for the t eatment of skin and nail infections.

• 抗菌性

  Terbinafine is active against a wide range of pathogenic fungi, including dermatophytes (Epidermophyton, Microsporum and Trichophyton spp.), various Candida spp., Aspergillus spp., some dimorphic fungi (Blastomyces dermatitidis, Histoplasma capsulatum and Sporothrix schenckii) and many dematiaceous fungi.

• 獲得抵抗性

  Resistance has not been reported.

• 応用例（製薬）

  A synthetic allylamine available as the hydrochloride for oral and topical administration.

• 薬物動態学

  Oral absorption: 70–80%
  C_max 250 mg oral: c. 1 mg/L after 2 h
  Plasma half-life: c. 17 h
  Volume of distribution: 1000 L
  Plasma protein binding: >99%
  Blood concentrations increase in proportion to dosage. It is lipophilic and is rapidly and extensively distributed to body tissues. It reaches the stratum corneum by diffusion through the dermis and epidermis, and secretion in sebum. Diffusion from the nail bed is the major factor in its rapid penetration of nails. It is metabolized by the liver and the inactive metabolites are mostly excreted in the urine. The elimination half-life is prolonged in patients with hepatic or renal impairment.

• 臨床応用

  Terbinafine hydrochloride can be used in Tinea pedis, tinea corporis, tinea cruris, tinea capitis, Onychomycosis caused by dermatophytes.

• 副作用

  These include abdominal discomfort, loss of appetite, nausea, diarrhea, headache, impairment of taste, rash and urticaria. Serious skin reactions, including Stevens– Johnson syndrome, and rare hepatotoxic reactions, including jaundice, cholestasis and hepatitis, are occasionally encountered.
