| + | '''Dosage''': Fluconazole is marketed in the U.S. as tablets of 50, 100, 150, and 200 mg for oral administration, powder for oral suspension providing 10 and 40 mg/mL, and intravenous solutions containing 2 mg/mL in saline and in dextrose solution. The daily dose of fluconazole should be based on the infecting organism and the patient’s response to therapy. Generally, recommended dosages are 50 to 400 mg once daily for either oral or intravenous administration. A loading dose of twice the daily maintenance dose is generally administered on the first day of therapy. Prolonged maintenance therapy may be required to prevent relapse. Children are treated with 12 mg/kg once daily (maximum 600 mg/day) without a loading dose. In adult patients, doses of up to 1200 mg have been safely administered in clinical trials for the treatment of cryptococcal meningitis. | ||

1.1 Itraconazole (伊曲康唑)
1.2 Fluconazole (氟康唑)
Dosage: Fluconazole is marketed in the U.S. as tablets of 50, 100, 150, and 200 mg for oral administration, powder for oral suspension providing 10 and 40 mg/mL, and intravenous solutions containing 2 mg/mL in saline and in dextrose solution. The daily dose of fluconazole should be based on the infecting organism and the patient’s response to therapy. Generally, recommended dosages are 50 to 400 mg once daily for either oral or intravenous administration. A loading dose of twice the daily maintenance dose is generally administered on the first day of therapy. Prolonged maintenance therapy may be required to prevent relapse. Children are treated with 12 mg/kg once daily (maximum 600 mg/day) without a loading dose. In adult patients, doses of up to 1200 mg have been safely administered in clinical trials for the treatment of cryptococcal meningitis.
剂量'： 氟康唑在美国销售为 50、100、150 和 200 mg 口服片剂，口服混悬剂粉末提供 10 和 40 mg/mL，以及含有 2 mg/mL 的盐水和葡萄糖溶液的静脉注射溶液。氟康唑的每日剂量应基于感染微生物和患者对治疗的反应。通常，推荐剂量为 50 至 400 毫克，每天一次，口服或静脉给药。通常在治疗的第一天给予每日维持剂量 2 倍的负荷剂量。可能需要长期维持治疗以防止复发。儿童用 12 mg/kg 每天一次（最大 600 mg/天）治疗，无负荷剂量。在成年患者中，在治疗隐球菌性脑膜炎的临床试验中，已安全地施用高达 1200 毫克的剂量。
1.3 特比萘芬 (Terbinafine)
Terbinafine is a synthetic allylamine, structurally similar to the topical agent naftifine (see discussion that follows). It inhibits fungal squalene epoxidase and thereby reduces ergosterol biosynthesis.
特比萘芬是一种合成烯丙胺，在结构上类似于外用剂萘替芬（见下面的讨论）。它抑制真菌角鲨烯环氧化酶，从而减少麦角甾醇的生物合成。
ADME: Terbinafine is well absorbed, but bioavailability is about 40% due to first-pass metabolism in the liver. The drug accumulates in skin, nails, and fat. The initial t1/2 is about 12 h but extends to 200 to 400 h at steady state. Terbinafine is not recommended in patients with marked azotemia or hepatic failure. Rifampin decreases and cimetidine increases plasma terbinafine concentrations.
ADME：特比萘芬吸收良好，但由于肝脏中的首过代谢，生物利用度约为 40%。该药物在皮肤、指甲和脂肪中积累。初始 t1/2 约为 12 小时，但在稳态下延长至 200 至 400 小时。不推荐将特比萘芬用于明显氮质血症或肝功能衰竭的患者。利福平降低血浆特比萘芬浓度，西咪替丁增加血浆特比萘芬浓度。
Therapeutic Uses: Terbinafine, given as one 250-mg tablet daily for adults, is somewhat more effective than itraconazole for nail onychomycosis. Duration of treatment varies with the site of infection but typically ranges between 6 and 12 weeks. The efficacy for the treatment of onychomycosis can be improved by the simultaneous use of amorolfine 5% nail lacquer (amorolfine is not approved for use in the U.S.). Terbinafine is also effective for the treatment of tinea capitis and has been used for the off-label treatment of ringworm elsewhere on the body.
治疗用途： 特比萘芬，成人每天一片 250 毫克片剂，比伊曲康唑对指甲甲真菌病更有效。治疗持续时间因感染部位而异，但通常在 6 至 12 周之间。同时使用 5% 阿莫罗芬指甲油可以提高治疗甲癣的疗效（阿莫罗芬在美国未获批使用）。特比萘芬对治疗头癣也有效，并已用于身体其他部位的癣的超说明书治疗。
Adverse Effects: The drug is well tolerated, with a low incidence of GI distress, headache, or rash. Very rarely, fatal hepatotoxicity, severe neutropenia, Stevens-Johnson syndrome, or toxic epidermal necrolysis may occur. Systemic terbinafine therapy for onychomycosis should be postponed until after pregnancy is complete.
不良反应：该药物耐受性良好，胃肠道不适、头痛或皮疹的发生率较低。极少数情况下，可能会发生致命的肝毒性、严重的中性粒细胞减少、Stevens-Johnson 综合征或中毒性表皮坏死松解症。甲癣的全身性特比萘芬治疗应推迟到妊娠完成后。
