伐昔洛韦(葛兰素史克)说明书
PRESCRIBING INFORMATION ZOVIRAX®(acyclovir)CapsulesZOVIRAX®(acyclovir)TabletsZOVIRAX®(acyclovir)SuspensionDESCRIPTIONZOVIRAX is the brand name for acyclovir, a synthetic nucleoside analogue active against herpesviruses. ZOVIRAX Capsules, Tablets, and Suspension are formulations for oral administration. Each capsule of ZOVIRAX contains 200 mg of acyclovir and the inactive ingredients corn starch, lactose, magnesium stearate, and sodium lauryl sulfate. The capsule shell consists of gelatin, FD&C Blue No. 2, and titanium dioxide. May contain one or more parabens. Printed with edible black ink.Each 800-mg tablet of ZOVIRAX contains 800 mg of acyclovir and the inactive ingredients FD&C Blue No. 2, magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate.Each 400-mg tablet of ZOVIRAX contains 400 mg of acyclovir and the inactive ingredients magnesium stearate, microcrystalline cellulose, povidone, and sodium starch glycolate.Each teaspoonful (5 mL) of ZOVIRAX Suspension contains 200 mg of acyclovir and the inactive ingredients methylparaben 0.1% and propylparaben 0.02% (added as preservatives), carboxymethylcellulose sodium, flavor, glycerin, microcrystalline cellulose, and sorbitol.Acyclovir is a white, crystalline powder with the molecular formula C8H11N5O3 and a molecular weight of 225. The maximum solubility in water at 37°C is 2.5 mg/mL. The pka’s of acyclovir are 2.27 and 9.25.The chemical name of acyclovir is 2-amino-1,9-dihydro-9-[(2-hydroxyethoxy)methyl]-6H-purin-6-one; it has the following structural formula:VIROLOGYMechanism of Antiviral Action: Acyclovir is a synthetic purine nucleoside analogue with in vitro and in vivo inhibitory activity against herpes simplex virus types 1 (HSV-1), 2 (HSV-2), and varicella-zoster virus (VZV).The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase (TK) encoded by HSV and VZV. This viral enzyme converts acyclovir into acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate bycellular guanylate kinase and into triphosphate by a number of cellular enzymes. In vitro, acyclovir triphosphate stops replication of herpes viral DNA. This is accomplished in 3 ways: 1) competitive inhibition of viral DNA polymerase, 2) incorporation into and termination of the growing viral DNA chain, and 3) inactivation of the viral DNA polymerase. The greater antiviral activity of acyclovir against HSV compared to VZV is due to its more efficient phosphorylation by the viral TK. Antiviral Activities: The quantitative relationship between the in vitro susceptibility of herpesviruses to antivirals and the clinical response to therapy has not been established in humans, and virus sensitivity testing has not been standardized. Sensitivity testing results, expressed as the concentration of drug required to inhibit by 50% the growth of virus in cell culture (IC 50), vary greatly depending upon a number of factors. Using plaque-reduction assays, the IC 50 against herpes simplex virus isolates ranges from 0.02 to 13.5 mcg/mL for HSV-1 and from 0.01 to 9.9 mcg/mL for HSV-2. The IC 50 for acyclovir against most laboratory strains and clinical isolates of VZV ranges from 0.12 to10.8 mcg/mL. Acyclovir also demonstrates activity against the Oka vaccine strain of VZV with a mean IC 50 of 1.35 mcg/mL.Drug Resistance: Resistance of HSV and VZV to acyclovir can result from qualitative andquantitative changes in the viral TK and/or DNA polymerase. Clinical isolates of HSV and VZV with reduced susceptibility to acyclovir have been recovered from immunocompromised patients, especially with advanced HIV infection. While most of the acyclovir-resistant mutants isolated thus far from immunocompromised patients have been found to be TK-deficient mutants, other mutants involving the viral TK gene (TK partial and TK altered) and DNA polymerase have been isolated. TK-negative mutants may cause severe disease in infants and immunocompromised adults. The possibility of viral resistance to acyclovir should be considered in patients who show poor clinical response during therapy.CLINICAL PHARMACOLOGYPharmacokinetics: The pharmacokinetics of acyclovir after oral administration have been evaluated in healthy volunteers and in immunocompromised patients with herpes simplex or varicella-zoster virus infection. Acyclovir pharmacokinetic parameters are summarized in Table 1.Table 1. Acyclovir Pharmacokinetic Characteristics (Range)Parameter RangePlasma protein binding 9% to 33%Plasma elimination half-life 2.5 to 3.3 hrAverage oral bioavailability 10% to 20%**Bioavailability decreases with increasing dose.In one multiple-dose, crossover study in healthy subjects (n = 23), it was shown that increases in plasma acyclovir concentrations were less than dose proportional with increasing dose, as shown in Table 2. The decrease in bioavailability is a function of the dose and not the dosage form.Table 2. Acyclovir Peak and Trough Concentrations at Steady StateParameter 200 mg 400 mg 800 mgmax SS C 0.83 mcg/mL 1.21 mcg/mL 1.61 mcg/mLtrough SS C 0.46 mcg/mL 0.63 mcg/mL 0.83 mcg/mLThere was no effect of food on the absorption of acyclovir (n = 6); therefore, ZOVIRAX Capsules, Tablets, and Suspension may be administered with or without food.The only known urinary metabolite is 9-[(carboxymethoxy)methyl]guanine.Special Populations: Adults with Impaired Renal Function:The half-life and total body clearance of acyclovir are dependent on renal function. A dosage adjustment is recommended for patients with reduced renal function (see DOSAGE AND ADMINISTRATION).Geriatrics:Acyclovir plasma concentrations are higher in geriatric patients compared to younger adults, in part due to age-related changes in renal function. Dosage reduction may be required in geriatric patients with underlying renal impairment (see PRECAUTIONS: Geriatric Use).Pediatrics:In general, the pharmacokinetics of acyclovir in pediatric patients is similar to that of adults. Mean half-life after oral doses of 300 mg/m2 and 600 mg/m2 in pediatric patients aged7 months to 7 years was 2.6 hours (range 1.59 to 3.74 hours).Drug Interactions: Coadministration of probenecid with intravenous acyclovir has been shown to increase the mean acyclovir half-life and the area under the concentration-time curve. Urinary excretion and renal clearance were correspondingly reduced.Clinical Trials: Initial Genital Herpes: Double-blind, placebo-controlled studies have demonstrated that orally administered ZOVIRAX significantly reduced the duration of acute infection and duration of lesion healing. The duration of pain and new lesion formation was decreased in some patient groups.Recurrent Genital Herpes:Double-blind, placebo-controlled studies in patients with frequent recurrences (6 or more episodes per year) have shown that orally administered ZOVIRAX given daily for 4 months to 10 years prevented or reduced the frequency and/or severity of recurrences in greater than 95% of patients.In a study of patients who received ZOVIRAX400 mg twice daily for 3 years, 45%, 52%, and 63% of patients remained free of recurrences in the first, second, and third years, respectively. Serial analyses of the 3-month recurrence rates for the patients showed that 71% to 87% were recurrence free in each quarter.Herpes Zoster Infections:In a double-blind, placebo-controlled study of immunocompetent patients with localized cutaneous zoster infection, ZOVIRAX (800 mg 5 times daily for 10 days) shortened the times to lesion scabbing, healing, and complete cessation of pain, and reduced the duration of viral shedding and the duration of new lesion formation.In a similar double-blind, placebo-controlled study, ZOVIRAX (800 mg 5 times daily for7 days) shortened the times to complete lesion scabbing, healing, and cessation of pain; reduced the duration of new lesion formation; and reduced the prevalence of localized zoster-associated neurologic symptoms (paresthesia, dysesthesia, or hyperesthesia).Treatment was begun within 72 hours of rash onset and was most effective if started within the first 48 hours.Adults greater than 50 years of age showed greater benefit.Chickenpox:Three randomized, double-blind, placebo-controlled trials were conducted in 993 pediatric patients aged 2 to 18 years with chickenpox. All patients were treated within 24 hours after the onset of rash. In 2 trials, ZOVIRAX was administered at 20 mg/kg 4 times daily (up to3,200 mg per day) for 5 days. In the third trial, doses of 10, 15, or 20 mg/kg were administered 4 times daily for 5 to 7 days. Treatment with ZOVIRAX shortened the time to 50% healing; reduced the maximum number of lesions; reduced the median number of vesicles; decreased the median number of residual lesions on day 28; and decreased the proportion of patients with fever, anorexia, and lethargy by day 2. Treatment with ZOVIRAX did not affect varicella-zoster virus-specific humoral or cellular immune responses at 1 month or 1 year following treatment.INDICATIONS AND USAGEHerpes Zoster Infections:ZOVIRAX is indicated for the acute treatment of herpes zoster (shingles).Genital Herpes:ZOVIRAX is indicated for the treatment of initial episodes and the management of recurrent episodes of genital herpes.Chickenpox:ZOVIRAX is indicated for the treatment of chickenpox (varicella). CONTRAINDICATIONSZOVIRAX is contraindicated for patients who develop hypersensitivity to acyclovir or valacyclovir.WARNINGSZOVIRAX Capsules, Tablets, and Suspension are intended for oral ingestion only. Renal failure, in some cases resulting in death, has been observed with acyclovir therapy (see ADVERSE REACTIONS: Observed During Clinical Practice and OVERDOSAGE). Thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), which has resulted in death, has occurred in immunocompromised patients receiving acyclovir therapy.PRECAUTIONSDosage adjustment is recommended when administering ZOVIRAX to patients with renal impairment (see DOSAGE AND ADMINISTRATION). Caution should also be exercised when administering ZOVIRAX to patients receiving potentially nephrotoxic agents since this may increase the risk of renal dysfunction and/or the risk of reversible central nervous system symptoms such as those that have been reported in patients treated with intravenous acyclovir. Adequate hydration should be maintained.Information for Patients: Patients are instructed to consult with their physician if they experience severe or troublesome adverse reactions, they become pregnant or intend to become pregnant, they intend to breastfeed while taking orally administered ZOVIRAX, or they have any other questions.Patients should be advised to maintain adequate hydration.Zoster: There are no data on treatment initiated more than 72 hours after onset of the Herpeszoster rash. Patients should be advised to initiate treatment as soon as possible after a diagnosis of herpes zoster.Genital Herpes Infections: Patients should be informed that ZOVIRAX is not a cure for genital herpes. There are no data evaluating whether ZOVIRAX will prevent transmission of infection to others. Because genital herpes is a sexually transmitted disease, patients should avoid contact with lesions or intercourse when lesions and/or symptoms are present to avoid infecting partners. Genital herpes can also be transmitted in the absence of symptoms through asymptomatic viral shedding. If medical management of a genital herpes recurrence is indicated, patients should be advised to initiate therapy at the first sign or symptom of an episode.Chickenpox: Chickenpox in otherwise healthy children is usually a self-limited disease of mild to moderate severity. Adolescents and adults tend to have more severe disease. Treatment was initiated within 24 hours of the typical chickenpox rash in the controlled studies, and there is no information regarding the effects of treatment begun later in the disease course.Drug Interactions:See CLINICAL PHARMACOLOGY: Pharmacokinetics.Carcinogenesis, Mutagenesis, Impairment of Fertility: The data presented below include references to peak steady-state plasma acyclovir concentrations observed in humans treated with800 mg given orally 5 times a day (dosing appropriate for treatment of herpes zoster) or 200 mg given orally 5 times a day (dosing appropriate for treatment of genital herpes). Plasma drug concentrations in animal studies are expressed as multiples of human exposure to acyclovir at the higher and lower dosing schedules (see CLINICAL PHARMACOLOGY: Pharmacokinetics).Acyclovir was tested in lifetime bioassays in rats and mice at single daily doses of up to450 mg/kg administered by gavage. There was no statistically significant difference in the incidence of tumors between treated and control animals, nor did acyclovir shorten the latency of tumors. Maximum plasma concentrations were 3 to 6 times human levels in the mouse bioassay and 1 to 2 times human levels in the rat bioassay.Acyclovir was tested in 16 in vitro and in vivo genetic toxicity assays. Acyclovir was positive in 5 of the assays.Acyclovir did not impair fertility or reproduction in mice (450 mg/kg/day, p.o.) or in rats(25 mg/kg/day, s.c.). In the mouse study, plasma levels were 9 to 18 times human levels, while in the rat study, they were 8 to 15 times human levels. At higher doses (50 mg/kg/day, s.c.) in rats and rabbits (11 to 22 and 16 to 31 times human levels, respectively) implantation efficacy, but not litter size, was decreased. In a rat peri- and post-natal study at 50 mg/kg/day, s.c., there was a statistically significant decrease in group mean numbers of corpora lutea, total implantation sites, and live fetuses.No testicular abnormalities were seen in dogs given 50 mg/kg/day, IV for 1 month (21 to41 times human levels) or in dogs given 60 mg/kg/day orally for 1 year (6 to 12 times human levels). Testicular atrophy and aspermatogenesis were observed in rats and dogs at higher dose levels. Pregnancy: Teratogenic Effects:Pregnancy Category B. Acyclovir administered during organogenesis was not teratogenic in the mouse (450 mg/kg/day, p.o.), rabbit (50 mg/kg/day, s.c. and IV), or rat (50 mg/kg/day, s.c.). These exposures resulted in plasma levels 9 and 18, 16 and 106, and 11 and 22 times, respectively, human levels.There are no adequate and well-controlled studies in pregnant women. A prospective epidemiologic registry of acyclovir use during pregnancy was established in 1984 and completed in April 1999. There were 749 pregnancies followed in women exposed to systemic acyclovir during the first trimester of pregnancy resulting in 756 outcomes. The occurrence rate of birth defects approximates that found in the general population. However, the small size of the registry is insufficient to evaluate the risk for less common defects or to permit reliable or definitive conclusions regarding the safety of acyclovir in pregnant women and their developing fetuses. Acyclovir should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.Nursing Mothers: Acyclovir concentrations have been documented in breast milk in 2 women following oral administration of ZOVIRAX and ranged from 0.6 to 4.1 times corresponding plasma levels. These concentrations would potentially expose the nursing infant to a dose of acyclovir up to 0.3 mg/kg/day. ZOVIRAX should be administered to a nursing mother with caution and only when indicated.Pediatric Use: Safety and effectiveness of oral formulations of acyclovir in pediatric patients younger than 2 years of age have not been established.Geriatric Use: Of 376 subjects who received ZOVIRAX in a clinical study of herpes zoster treatment in immunocompetent subjects ≥50 years of age, 244 were 65 and over while 111 were 75 and over. No overall differences in effectiveness for time to cessation of new lesion formation or time to healing were reported between geriatric subjects and younger adult subjects. The duration of pain after healing was longer in patients 65 and over. Nausea, vomiting, and dizziness were reported more frequently in elderly subjects. Elderly patients are more likely to have reduced renal function and require dose reduction. Elderly patients are also more likely to have renal or CNS adverse events. With respect to CNS adverse events observed during clinical practice, somnolence, hallucinations, confusion, and coma were reported more frequently in elderly patients (see CLINICAL PHARMACOLOGY, ADVERSE REACTIONS: Observed During Clinical Practice, and DOSAGE AND ADMINISTRATION).ADVERSE REACTIONSHerpes Simplex: Short-Term Administration:The most frequent adverse events reported during clinical trials of treatment of genital herpes with ZOVIRAX 200 mg administered orally 5 times daily every 4 hours for 10 days were nausea and/or vomiting in 8 of 298 patient treatments (2.7%). Nausea and/or vomiting occurred in 2 of 287 (0.7%) patients who received placebo.Administration:The most frequent adverse events reported in a clinical trial for Long-Termthe prevention of recurrences with continuous administration of 400 mg (two 200-mg capsules) 2 times daily for 1 year in 586 patients treated with ZOVIRAX were nausea (4.8%) and diarrhea (2.4%). The589 control patients receiving intermittent treatment of recurrences with ZOVIRAX for 1 year reported diarrhea (2.7%), nausea (2.4%), and headache (2.2%).Herpes Zoster: The most frequent adverse event reported during 3 clinical trials of treatment of herpes zoster (shingles) with 800 mg of oral ZOVIRAX 5 times daily for 7 to 10 days in 323 patients was malaise (11.5%). The 323 placebo recipients reported malaise (11.1%).Chickenpox: The most frequent adverse event reported during 3 clinical trials of treatment of chickenpox with oral ZOVIRAX at doses of 10 to 20 mg/kg 4 times daily for 5 to 7 days or 800 mg4 times daily for5 days in 495 patients was diarrhea (3.2%). The 498 patients receiving placebo reported diarrhea (2.2%).Observed During Clinical Practice: In addition to adverse events reported from clinical trials, the following events have been identified during post-approval use of ZOVIRAX. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, potential causal connection to ZOVIRAX, or a combination of these factors.General:Anaphylaxis, angioedema, fever, headache, pain, peripheral edema.Nervous:Aggressive behavior, agitation, ataxia, coma,confusion, decreased consciousness, delirium, dizziness, dysarthria, encephalopathy, hallucinations, paresthesia, psychosis, seizure, somnolence, tremors. These symptoms may be marked, particularly in older adults or in patients with renal impairment (see PRECAUTIONS).Digestive: Diarrhea, gastrointestinal distress, nausea.Hematologic and Lymphatic:Anemia, leukocytoclastic vasculitis, leukopenia, lymphadenopathy, thrombocytopenia.Hepatobiliary Tract and Pancreas: Elevated liver function tests, hepatitis, hyperbilirubinemia, jaundice.Musculoskeletal:Myalgia.Skin:Alopecia, erythema multiforme, photosensitive rash, pruritus, rash, Stevens-Johnson syndrome, toxic epidermal necrolysis, urticaria.Senses:SpecialVisual abnormalities.Urogenital: Renal failure, elevated blood urea nitrogen, elevated creatinine, hematuria (see WARNINGS).OVERDOSAGEOverdoses involving ingestion of up to 100 capsules (20 g) have been reported. Adverse events that have been reported in association with overdosage include agitation, coma, seizures, and lethargy. Precipitation of acyclovir in renal tubules may occur when the solubility (2.5 mg/mL) is exceeded in the intratubular fluid. Overdosage has been reported following bolus injections or inappropriately high doses and in patients whose fluid and electrolyte balance were not properly monitored. This has resulted in elevated BUN and serum creatinine and subsequent renal failure. In the event of acute renal failure and anuria, the patient may benefit from hemodialysis until renal function is restored (see DOSAGE AND ADMINISTRATION).DOSAGE AND ADMINISTRATIONAcute Treatment of Herpes Zoster:800 mg every 4 hours orally, 5 times daily for 7 to 10 days. Genital Herpes: Treatment of Initial Genital Herpes:200 mg every 4 hours, 5 times daily for 10 days.Chronic Suppressive Therapy for Recurrent Disease:400 mg 2 times daily for up to 12 months, followed by re-evaluation. Alternative regimens have included doses ranging from 200 mg 3 times daily to 200 mg 5 times daily.The frequency and severity of episodes of untreated genital herpes may change over time. After 1 year of therapy, the frequency and severity of the patient’s genital herpes infection should be re-evaluated to assess the need for continuation of therapy with ZOVIRAX.IntermittentTherapy:200 mg every 4 hours, 5 times daily for 5 days. Therapy should be initiated at the earliest sign or symptom (prodrome) of recurrence.Treatment of Chickenpox:Children (2 years of age and older): 20 mg/kg per dose orally4 times daily (80 mg/kg/day) for5 days. Children over 40 kg should receive the adult dose for chickenpox.Adults and Children over 40 kg:800 mg 4 times daily for 5 days.Intravenous ZOVIRAX is indicated for the treatment of varicella-zoster infections in immunocompromised patients.When therapy is indicated, it should be initiated at the earliest sign or symptom of chickenpox. There is no information about the efficacy of therapy initiated more than 24 hours after onset of signs and symptoms.Patients With Acute or Chronic Renal Impairment: In patients with renal impairment, the dose of ZOVIRAX Capsules, Tablets, or Suspension should be modified as shown in Table 3:Table 3. Dosage Modification for Renal ImpairmentCreatinine Adjusted Dosage RegimenNormal Dosage RegimenClearance(mL/min/1.73 m2)Dose(mg) Dosing Interval200 mg every 4 hours >10 200 every 4 hours, 5x daily0-10 200 every 12 hours400 mg every 12 hours >100-10 400200every 12 hoursevery 12 hours800 mg every 4 hours >25 800 every 4 hours, 5x daily10-25 800 every 8 hours0-10 800 every 12 hours Hemodialysis:For patients who require hemodialysis, the mean plasma half-life of acyclovir during hemodialysis is approximately 5 hours. This results in a 60% decrease in plasma concentrations following a 6-hour dialysis period. Therefore, the patient’s dosing schedule should be adjusted so that an additional dose is administered after each dialysis.Peritoneal Dialysis:No supplemental dose appears to be necessary after adjustment of the dosing interval.Bioequivalence of Dosage Forms: ZOVIRAX Suspension was shown to be bioequivalent to ZOVIRAX Capsules (n = 20) and 1 ZOVIRAX 800-mg tablet was shown to be bioequivalent to 4 ZOVIRAX 200-mg capsules (n = 24).HOW SUPPLIEDZOVIRAX Capsules (blue, opaque cap and body) containing 200 mg acyclovir and printed with “Wellcome ZOVIRAX 200.”Bottle of 100 (NDC 0173-0991-55).Unit dose pack of 100 (NDC 0173-0991-56).Store at 15° to 25°C (59° to 77°F) and protect from moisture.ZOVIRAX Tablets (light blue, oval) containing 800 mg acyclovir and engraved with “ZOVIRAX 800.”Bottle of 100 (NDC 0173-0945-55).Store at 15° to 25°C (59° to 77°F) and protect from moisture.ZOVIRAX Tablets (white, shield-shaped) containing 400 mg acyclovir and engraved with "ZOVIRAX" on one side and a triangle on the other side.Bottle of 100 (NDC 0173-0949-55).Store at 15° to 25°C (59° to 77°F) and protect from moisture.ZOVIRAX Suspension (off-white, banana-flavored) containing 200 mg acyclovir in each teaspoonful (5 mL).Bottle of 1 pint (473 mL) (NDC 0173-0953-96).Store at 15° to 25°C (59° to 77°F).GlaxoSmithKlineResearch Triangle Park, NC 27709©2005, GlaxoSmithKline.

Methods A total of 120 patients were randomly divided into four groups: patients in group 1 were treated with 400 mg aciclovir, Bid for 6 months; those in group 2 were treated with 500 mg valaciclovir, qd for 6 months; those in group 3, were treated with 500 mg valaciclovir, Bid for 3 months; and those in group 4, were treated with 500 mg valaciclovir, Bid for 3 months, and then with 500 mg valaciclovir, qd for 3 months. The patients were observed for the recurrence of GH after treatment and were followed up, and the viral load of HSV-2 DNA was monitored. Results Compared with pre-therapy, the recurrence of GH was significantly reduced in all the 4 groups, especially ingroup 4. Administration of 500 mg valaciclovir, Bid, could inhibit the replication of HSV-2 efficiently, and the subsequent reduced dose treatment additionally inhibited the replication of HSV-2. Conclusion Valaciclovir can not only reduce the recurrence of GH, but also efficiently inhibit replication of HSV-2.【期刊名称】《首都医科大学学报》【年(卷),期】2011(032)006【总页数】4页(P834-837)【关键词】生殖器疱疹;伐昔洛韦;病毒抑制疗法【作者】毕建军;杨慧兰;樊建勇;张玲【作者单位】广州军区广州总医院皮肤科,广州510010;广州军区广州总医院皮肤科,广州510010;广州军区广州总医院皮肤科,广州510010;广州军区广州总医院皮肤科,广州510010【正文语种】中文【中图分类】R751.05生殖器疱疹(genital herpes,GH)是一种常见的性传播疾病,主要由单纯疱疹病毒2型(herpes simplex virus 2,HSV-2)引起。

药动学
本药水溶性好,口服吸收后在肝内迅速被水解酶水解成阿昔洛韦,血浆中测不出伐昔洛韦,但阿昔洛韦的血 浆浓度很高,可与静脉注射阿昔洛韦相比,且比口服阿昔洛韦要高3~5倍。本药生物利用度为65%,显著高于阿 昔洛韦,进餐后服用不影响其生物利用度。本药和血浆蛋白结合率ห้องสมุดไป่ตู้13.5%~17.9%,可由乳汁分泌。本药的分解 代谢在肝及肠壁内进行。由于快速分解为阿昔洛韦,本药的半衰期小于30min,而阿昔洛韦的半衰期在正常肾功 能时约3h。广泛分布于全身14个组织,可达小肠、肝、肾等组织,尤以淋巴结、皮肤中的浓度为最高,在脑组织 浓度最低。24h后可以从所有组织中清除,48h后全部剂量从尿和粪便中排除。代谢物主要从尿液中排除。其中阿 昔洛韦占46%~59%,8-羟基阿昔洛韦占25%~30%。在口服和静脉注射相同的前体药后,未代谢的前体药分别占 0.5%和6%,说明该药更适合于口服给药。血药浓度接近于静脉滴注ACV,对肾脏的毒性作用亦较轻,可更快地缩 短带状疱疹后遗神经痛的时间。
口服:1.带状疱疹:每次0.3g,每天2次,连续10天,总用量6g(最小用量1.8g,疗程3天)。2.单纯疱疹: 每次0.3g,每天2次,连续7天,总用量4.2g(最小用量1.8g,疗程3天)。3.生殖器疱疹:每次0.3g,每天2次, 连续5~10天。4.尖锐湿疣:每次0.3g,每天2次,连续9~27天 。
