Herpes simplex viruses are known to be among the most common disease-causing microorganisms. Their prevalence can exceed 90% depending on the socioeconomic status of the population. Since the number of immunocompromised patients has increased because of the increased incidence in the acquired immunodeficiency syndrome and an increase in organ transplantation, herpes virus infection may have a greater clinical significance. While treatment of otherwise healthy individuals will not usually cause any clinical problems herpes infection in an immunocompromised patient can have severe consequences. Additionally, development of viral resistance can be observed that may require alternative drugs in treatment. We present a case history of a man with a B-cell chronic lymphocytic leukemia that was associated with a very unusual herpes simplex virus infection in the nasal vestibule. Possible causes for the development of resistance in herpes infections and the use of famciclovir and forscarnet as two therapeutic alternatives to aciclovir are discussed.

Exacerbations of genital herpes coinciding with MS relapses suggest a potential link between the development of NABs and inhibition of anti-viral action of endogenous IFNβ. This case highlights that NABs not only decreases exogenous IFNβ treatment efficacy, but may also interfere with anti-viral properties of endogenous IFNβ. Investigating patients who are treated with biological medication will allow us to better understand the biology and signalling pathways in humans.

Epstein-Barr virus is an ubiquitous member of the human herpes virus family. A specific antigen structure of the Epstein-Barr virus was discovered in the last decade. It was possible to diagnose some unusual clinical manifestations of EBV infections and its clinical course by different serologic analyses (immunofluorescent tests, immunoenzyme assay and polymerase chain reaction). This is very important in cases of atypical primary infections (hepatitis, meningoencephalitis), chronic mononucleosis and lymphoproliferative disorders and nasopharyngeal carcinoma. Famciclovir, a new antiviral agent (peroral form of penciclovir) may play an important role in the therapy of these infections.

We carried out a survey of all UK genitourinary (GU) medicine clinics, via postal questionnaire, in order to evaluate the current management of recurrent genital herpes (RGH) in the GU medicine setting. Respondents were invited to answer questions regarding various aspects of herpes simplex virus (HSV) management. There was a 62% response rate. Analysis of the returned surveys revealed that the vast majority of clinics (96%) provided drug treatment for RGH, with 81% having a clinic policy for the management of genital herpes (GH). A majority (64%) of clinics had access to some type of counselling or psychological therapy and 47% encouraged collaboration with primary care for follow-up prescribing. Of the clinics providing drug therapy for RGH, 80% used aciclovir alone with smaller numbers having access to aciclovir, famciclovir and valaciclovir. While many clinics are meeting the British Association of Sexual Health and HIV (BASHH) guidelines, improvements can be made to increase the availability of psychological support to patients with HSV and improve links with primary care.

Cats were treated orally with famciclovir (90 mg/kg; n = 10) or a similar volume of lactose (400 mg; 6) 3 times/d for 21 days. Cats were inoculated with FHV-1 and administered the first treatment dose on day 0. Disease score; weight; results of urinalysis, serum biochemical analysis, and CBC; histologic conjunctivitis score; herpetic DNA shedding; goblet cell density; anti-FHV-1 antibody concentration; and plasma penciclovir concentration were measured.

The antiherpetic drugs acyclovir (ACV, valaciclovir) and penciclovir (famciclovir) are phosphorylated by viral thymidine kinase and terminate DNA synthesis. ASP2151 (amenamevir) and foscavir (PFA) directly inhibit viral helicase-primase and DNA polymerase, respectively, and inhibit replication of herpes simplex virus (HSV) and varicella-zoster virus. ACV, ASP2151, and PFA all inhibit HSV with a different mechanism of action and as a consequence, the kinetics of viral DNA accumulation and progeny virus production differ. This study focused on how viral DNA synthesis and its related events in the replication cycle would influence anti-HSV action of ACV, ASP2151, and PFA. ASP2151 suppressed HSV replication more efficiently than ACV at 10 × 50% effective concentration of plaque formation (EC50), when treatments were started 0-24 h after infection. ASP2151 and PFA were more potent than ACV in suppressing viral DNA synthesis and infectious virus production when they were added up to 3 h following infection. The virus replicated in the presence of ACV was compared for the ratios of HSV DNA copy number to infectivity with that without ACV and infectivity of ACV-treated virus was less efficient than that without ACV-treatment. The EC50 of infected cells in the time course after infection was preserved in PFA, limited in ASP2151, and much increased for ACV, indicating that viral DNA synthesis had little effect on antiviral action of PFA and ASP2151 but reduced the susceptibility of ACV. ASP2151 showed a preferable profile as an anti-herpetic agent with a better pharmacokinetic profile than ACV.

Our data show that these devices release penciclovir with a burst of drug delivery until the tenth day of release, then at an average rate of 5.063 ± 1.704 μg per day through the next 50 days with near zero-order kinetics (in comparison to MED-4750-acyclovir devices, which show the same burst kinetics and average 2.236 ± 0.625 μg/day thereafter). Furthermore, these devices suppress primary infection of FHV-1 in a cell culture system.

Famvir (famciclovir), manufactured by SmithKline Beecham Pharmaceuticals, has been shown to suppress herpes simplex virus (HSV) infections in people with HIV. Over a period of 4 months, 97 percent of patients treated with the drug did not experience any recurrences. The drug cleared the initial lesions, and most patients remained free of recurrences during the trial. Famvir was well tolerated, with diarrhea being the most commonly reported side effect. These findings could have a major impact on the quality of life for HIV and HSV co-infected patients. HIV patients often experience severe herpes infections, some causing potentially life-threatening complications. The company also sells a cream used for herpes cold sores and is developing an intravenous treatment for immunocompromised individuals, including those who have had chemotherapy for cancer.

The duration of bortezomib therapy was 1 to 164 weeks (median, 16 weeks). The total duration of exposure to bortezomib was 4150 weeks (80 patient-years). Except for the occasional missed dose, the self-reported compliance with antiviral prophylaxis was 100%. Not a single episode of herpes zoster was reported during this period. No adverse effects were noted that could be definitely attributed to acyclovir, valacyclovir, or famciclovir.

Several guanosine analogues, i.e. acyclovir (and its oral prodrug valaciclovir), penciclovir (in its oral prodrug form, famciclovir) and ganciclovir, are widely used for the treatment of herpesvirus (i.e. HSV-1, HSV-2, VZV and HCMV) infections. In recent years, several new guanosine analogues have been developed, including the 3-membered (cyclopropyl) sugar derivative A-5021 and the 6-membered D- and L-cyclohexenyl derivatives. Prominent features shared by all guanosine analogues are the following. They depend for their phosphorylation on the virus-encoded thymidine kinase (TK), which makes them particularly effective against those viruses (HSV-1, HSV-2 and VZV) that encoded for such TK. They are also active against HCMV, whether or not they are subject of phosphorylation by the HCMV-induced UL97 protein kinase. Their antiviral activity can be markedly potentiated by mycophenolic acid, an IMP dehydrogenase inhibitor, and they hold great promise, not only as antiviral agents for the treatment of herpesvirus infections, but also as antitumor agents for the combined gene therapy/chemotherapy of cancer, provided that (part of) the tumor cells have been transfected by the viral TK gene.

famvir drug classification

Increased understanding of the clinical and virological characteristics of recurrent genital herpes simplex virus infection in healthy adults, recognition of the critical importance of early initiation of therapy, which is best achieved by self-initiated therapy, and an appreciation of the excellent tolerance and safety of relatively high doses of available antiviral drugs have facilitated refinements to treatment regimens that are more convenient as well as efficacious and well-tolerated. This paper reviews the progressive convergence of these concepts to an efficacious, well-tolerated, 1-day, patient-initiated regimen for treating episodes of recurrent genital herpes.

During this time period, clarithromycin was on formulary, later delisted, and then relisted again. Valaciclovir and famciclovir were also added to the formulary. During the time clarithromycin was off the formulary, the rate of change in its monthly consumption was 0.0061 DDD/1000 population/day; following its relisting, the rate of change increased by 818% to 0.0560 DDD/1000 population/day (P=0.002). After the listing of valaciclovir on the formulary, the rate of change in its monthly consumption increased 57% from a baseline of 0.0014 to 0.0022 DDD/1000 population/day (P=0.07). A similar effect was seen with the addition of famciclovir to the formulary whereby the rate of change in monthly consumption increased from 0.0008 (before addition to the formulary) to 0.0018 (after addition to the formulary) (P

This case represents a middle-aged female with breast carcinoma. Cancer radiotherapy and chemotherapy created an immunosuppressed state, which allowed the development of herpes zoster ophthalmicus. Most patients who manifest zoster are immunocompetent. However, with the increased incidence of immunodeficient states (e.g., chemotherapy, organ transplantation and acquired immunodeficiency syndrome), clinicians are faced with a greater number of cases of zoster. In the immunodeficient population, especially, dissemination of the zoster and potentially damaging complications can occur.

The ability of prior infection from one elephant endotheliotropic herpesvirus (EEHV) type to protect against clinical or lethal infection from others remains an important question. This report describes viremia and subsequent shedding of EEHV1B in two juvenile 4-yr-old Asian elephants within 3 wk or 2 mo following significant infections caused by the rarely seen EEHV4. High levels of EEHV1B shedding were detected in the first elephant prior to emergence of infection and viremia in the second animal. The EEHV1B virus associated with both infections was identical to the strain causing infection in two herd mates previously. High EEHV viremia correlated with leukopenia and thrombocytopenia, which was followed by leukocytosis and thrombocytosis when clinical signs started to resolve. The observations from these cases should be beneficial for helping other institutions monitor and treat elephants infected with EEHV1, the most common virus associated with lethal buy famvir hemorrhagic disease.

Safety reporting from individual ongoing and completed clinical studies has demonstrated that famciclovir, the well-absorbed oral form of the antiherpesvirus agent penciclovir, has been well tolerated by more than 3,000 individuals worldwide. An integrated safety evaluation has been performed and includes over 1,600 patients from 11 completed, randomized, double-blind clinical trials and 2 open trials. The famciclovir population consisted of 816 herpes zoster patients (four trials), 409 patients with acute genital herpesvirus infections (seven trials), and 382 patients from two genital herpes suppression studies. Overall, the famciclovir-treated patient population was 57.7% female and ranged in age from 15 to 102 years (mean, 42.6 years), with 31.2% aged 50 years or more and 15.7% aged 65 years or more. The mean duration of exposure to famciclovir was 28.8 days (5.8 days excluding suppression studies). The total daily doses ranged from 125 mg to 2.25 g. The most common adverse experiences reported as related to study medication (famciclovir and placebo) were headache, nausea, and diarrhea. The frequencies of adverse experiences and laboratory abnormalities (hematology, clinical chemistry, and urinalysis parameters) were similar in both famciclovir and placebo recipients. Thus, safety data from the analysis of 13 completed clinical studies demonstrate that famciclovir is buy famvir tolerated well by patients with either herpes zoster or genital and has a safety profile comparable to that of placebo.

Viral lesions of the mouth in patients with HIV infection are common and these diseases any be a marker for HIV and disease progression. We review the spectrum of oral viral manifestations and discuss treatment modalities. The most common Epstein-Barr virus (EBV)-induced disorder in HIV-infected patients is oral hairy leukoplakia. EBV-related oral B-cell and T-cell lymphoma in AIDS patients has been described repeatedly. Herpes virus type 1 and rarely type 2 may lead to painful and resistant oral ulcers, and systemic treatment with acyclovir, valaciclovir or famciclovir is indicated. In acyclovir-resistant cases foscarnet is the treatment of choice. In recent years it has been documented that Kaposi's sarcoma, which often affects oral mucosa, is probably induced by herpesvirus type 8. Cytomegalovirus was found in 53% of cases with herpesviridae-induced mucosal ulcers as the only ulcerogenic viral agent in AIDS patients. In severe cytomegalovirus infection treatment with ganciclovir is helpful. Viral warts induced by different HPV may occur in the mouth. Several physical treatment modalities are possible in the oral mucosa. In AIDS patients mollusca contagiosa may occur as buy famvir large and atypical lesions in the face and lips and rarely in the oral cavity. Cryotherapy is a bloodless treatment in such patients.

A 16-year-old spayed female cat was evaluated for lagophthalmos and chronic exposure keratitis in both eyes. Ophthalmic examination revealed upper and lower eyelid entropion of the left eye (OS) and markedly decreased retropulsion, restricted eye movement, marked episcleral congestion, and severe keratitis of both eyes (OU). Magnetic resonance imaging of both orbits revealed extensive, irregular, contrast-enhancing tissue without evidence of osteolysis considered compatible with diffuse inflammatory tissue. Feline herpesvirus DNA was not detected in conjunctival samples. Partial temporary tarsorrhaphies were placed OU, and the cat was treated with topically administered erythromycin ointment OU, orally administered famciclovir and prednisolone, and sublingually administered buprenorphine. Little improvement was noted after 2 weeks. Six weeks after initial presentation, a left exenteration was performed and histopathology was consistent with idiopathic sclerosing orbital pseudotumor (ISOP). Ten weeks after initial presentation, the patient represented for weight loss and jaw pain. Computed tomography demonstrated disease progression in the right orbit and the patient was euthanized. Histopathology of the decalcified skull revealed an aggressive and highly infiltrative mass involving buy famvir the right orbit with extension to the maxilla, hard palate, nasal cavity and gingiva most consistent with feline restrictive orbital myofibroblastic sarcoma (FROMS). Clinical data from this patient support the reclassification of ISOP as FROMS. MRI and CT may provide supportive evidence for FROMS, but histopathology is necessary for definitive diagnosis. Aggressive and early surgical treatment, including bilateral exenteration, with adjunctive radiotherapy and/or chemotherapy should be considered for patients with FROMS.

The development of new nucleoside analogs, that inhibit the HBV reverse transcriptase activity, such as lamivudine, famciclovir and others, has provided recently an alternative to interferon therapy for chronic hepatitis B. buy famvir However, due to the kinetics of viral replication with a high rate of virus production, a relatively long half-life of virus (CCC) DNA in the nucleus of infected hepatocytes, long-term antiviral therapy with a reverse transcriptase inhibitor is required to eradicate viral infection. Recently, it has been reported that lamivudine therapy for chronic hepatitis B in immune competent patients may be associated with the selection of resistant strains in aproximately 20% of the patients after 12 months of therapy. Sequence analysis of the reverse transcriptase domain of resistant viral strains, at the time of viral breakthrough, revealed the occurrence of mutations located in the YMDD motif within the C domain of the viral enzyme with a methionine to valine (M552V) or to isoleucine (M5521) change. Recent reports on larger series of patients pointed that other mutations residing outside of the C domain but mainly in the B domain of the viral polymerase (L528M) could be associated with these mutations in the YMDD motif. The lamivudine resistant mutants, selected in vivo, can be classified in 2 main groups: group I with a double mutation L528M and M552V, and group II with a single mutation M5521. In vitro studies performed in cell culture showed that these mutants have a decreased replication capacity and are indeed resistant to lamivudine. With the development of new antiviral options, genotyping assays and quantitative determination of viremia with highly sensitive assay are clearly warranted for an optimal monitoring of antiviral therapy of chronic hepatitis B. In view of the experimental and clinical data, the capacity of new antiviral strategies based on combination of new inhibitors, including adefavir and entecavir, with immune modulators needs to be further evaluated in animal models and clinical trials to prevent the emergence of resistant viral strains.

Recurrent benign lymphocytic meningitis is a recurring, typically innocuous, painful form of aseptic meningitis. This syndrome is associated with transient neurological symptoms in one-half of afflicted patients. The causative agent is usually herpes simplex virus type 2, which can be confirmed by detection of viral DNA in the cerebrospinal fluid using polymerase chain reaction. Clinical disease resolves buy famvir spontaneously; however, acyclovir, valacyclovir, and famciclovir have been administered to some patients for both episodic therapy and suppression of recurrences. This therapy is thought to be beneficial, although there is no controlled trial data to support efficacy and safety.

Oral acyclovir did not reduce the incidence of PHN significantly. There is insufficient evidence from randomised controlled trials to determine whether other antiviral treatments prevent PHN. Additional well-designed, randomised controlled trials of famciclovir or other new antiviral agents, with a greater number of participants are needed. Future trials should buy famvir pay more attention to the severity of pain and quality of life of participants, and should be conducted among different subgroups of people, such as people who are immunocompromised.

Prolonged treatment of chronic hepatitis B virus (HBV) infection with lamivudine ([-]-beta-L-2',3'-dideoxy-3' thiacytidine) or famciclovir may select for viral mutants that are drug resistant due to point mutations in the polymerase gene. Determining whether such HBV mutants are sensitive to new antiviral agents is therefore important. We used a transient transfection system to compare the sensitivities of wild-type HBV and four lamivudine- and/or famciclovir-resistant HBV mutants to adefovir [9-(2- buy famvir phosphonyl-methoxyethyl)-adenine; PMEA] and the nucleoside analogues (-)-beta-D-2, 6-diaminopurine dioxolane (DAPD) and 2'-fluoro-5-methyl-beta-L-arabinofuranosyluracil (L-FMAU). The drug-resistant mutants contained amino acid substitutions in the polymerase protein. We found that the M550I and M550V plus L526M substitutions, which confer lamivudine resistance, did not confer cross-resistance to adefovir or DAPD, but conferred cross-resistance to L-FMAU. The M550V substitution in isolation conferred a similar phenotype to M550I, except that it did not confer significant resistance to L-FMAU. The L526M substitution, which is associated with famciclovir resistance, conferred cross-resistance to L-FMAU but not to adefovir or DAPD. Inhibition of HBV secretion by DAPD, L-FMAU, and adefovir did not always correlate with inhibition of the generation of intracellular HBV replicative intermediates, suggesting that these analogs may preferentially inhibit specific stages of the viral replication cycle.

Genitourinary medicine physicians have two main treatment options for the management of recurrent genital herpes: patient-initiated episodic or continuous suppressive therapy. As well as buy famvir effective disease control, important factors in selecting a regimen include patient acceptability and potential improvements in quality of life. Traditionally suppressive therapy has been favoured by many genitourinary physicians who have often been sceptical of the benefits of episodic therapy. This view has been challenged by several recent studies demonstrating the efficacy and the comparable psychological benefits of very short patient-initiated episodic therapy compared with suppressive therapy. In this article, we review the theory and development of episodic therapy, and discuss the recent evidence that suggests the benefits of ultra short episodic therapies for recurrent genital herpes may be much greater than previously demonstrated.

Aldehyde oxidase (AO) is a molybdo-flavo enzyme expressed predominantly in the liver, lung, and kidney. AO plays a major role in oxidation of aldehydes, as well as oxidation of various N-heterocyclic compounds of pharmacological and toxicological importance including antiviral (famciclovir), antimalarial (quinine), antitumour (methotrexate), and nicotine. The aim of this study was to investigate cytosolic aldehyde oxidase activity in human liver. Cytosolic AO was characterised using both the metabolism of N-[(2-dimethylamino)ethyl] acridine-4-carboxamide (DACA) and benzaldehyde to form DACA-9(10H)-acridone (quantified by HPLC with fluorescence detection) and benzoic acid (quantified buy famvir spectrophotometrically). Thirteen livers (10 female, 3 male) were examined. The intrinsic clearance (Vmax/Km) of DACA varied 18-fold (0.03-0.50 m/min/mg). Vmax ranged from 0.20-3.10 nmol/ min/mg, and Km ranged from 3.5-14.2 microM. In the same specimens, the intrinsic clearance for benzaldehyde varied 5-fold (0.40-1.8 ml/min/mg). Vmax ranged from 3.60-12.6 nmol/min/mg and Km ranged from 3.6-14.6 microM. Furthermore, there were no differences in AO activity between male and female human livers, nor was there any relationship to age of donor (range 29-73 years), smoking status, or disease status. In conclusion, our results showed that there are variations in AO activity in human liver. These variations in aldehyde oxidase activity might reflect individual variations or they might be due to AO stability during processing and storage.

Many researchers have attempted to identify the drugs capable of acting on the viral replication cycle and maintaining clinical remission in chronic hepatitis B. We evaluated the efficacy of antiviral drugs in chronic hepatitis B, by examination of 20 controlled and non-controlled trials conducted between 1985 and 1996. In chronic hepatitis B, adenine arabinoside and its monophosphate did not achieve satisfactory results, even though combination therapy with cortisone seemed to achieve very good results (remission rates ranging from 45% to 66% in patients treated). Lamivudine did not seem to furnish lasting effects in chronic hepatitis B, because many patients relapse after suspension of the treatment due to the appearance of HBV variants resistant to the drug Cymbalta Cost Help . Contrasting results were observed with famciclovir. Treatment of chronic hepatitis B, with this drug seemed capable of reducing HBV-DNA serum levels by a mean of 50% compared to pretreatment values, with normal alanine aminotransferase levels in about 30% of treated patients. Ganciclovir treatment of chronic hepatitis B seemed to furnish good, but transient, results. Even if no antiviral drug represented a valid alternative to interferon, antivirals may become the drugs of choice in chronic hepatitis B, because they are aimed at the etiology of disease.

The presence of herpes simplex virus-2 (HSV-2) shedding episodes correlates with transmission to sexual partners and neonates, and some episodes correlate with disease manifestations. HSV-2-targeted guanosine analogues are effective when given on a prophylactic basis, but do not completely eliminate recurrences, asymptomatic shedding or transmission. We sought to describe the impact of twice-daily aciclovir and famciclovir on shedding episodes. Norvasc 7 Mg

Daily antiviral therapy with famciclovir Norvasc Dosing and valacyclovir has been shown to be effective in reducing both symptomatic and asymptomatic reactivation of herpes simplex virus type 2 (HSV-2) when compared to placebo. However, few comparative studies between the 2 antivirals have been performed.

559 immunocompetent adults presenting with herpes zoster whose skin lesions were present for less than 72 h were randomized to receive famciclovir 750 mg once daily (od), 500 mg twice daily (bid), or 250 mg three times daily (tid), or aciclovir 800 mg five times daily. All treatments were given for 7 days. Participants were evaluated until complete healing or for 4 weeks Casodex Generic Name , whichever occurred first.

Viral pathogens have emerged as the most important microbial agents having deleterious effects on solid organ transplant (SOT) recipients. Antiviral chemoprophylaxis involves the administration of medications to abort transmission of, avoid reactivation of, or prevent progression to disease from, active viral infection. Cytomegalovirus (CMV) is the major microbial pathogen having a negative effect on SOT recipients. CMV causes infectious disease syndromes, augments iatrogenic immunosuppression and is commonly associated with opportunistic superinfection. CMV has also been implicated in the pathogenesis of rejection. Chemoprophylactic regimens for CMV have included oral aciclovir (acyclovir) at medium and high doses, intravenous and oral ganciclovir, and the prodrugs valaciclovir (valacyclovir) and valganciclovir. CMV prophylactic strategies should be stratified, with the highest-risk patients receiving the most 'potent' prophylactic regimens. Herpes simplex virus (HSV) reactivation in SOT recipients is more frequent, may become more invasive, takes longer to heal, and has greater potential for dissemination to visceral organs than it does in the immunocompetent host. Prophylactic regimens for CMV are also effective chemoprophylaxis against HSV; in the absence of CMV prophylaxis, aciclovir, valaciclovir or famciclovir should be used as HSV prophylaxis in seropositive recipients. Primary varicella-zoster virus (VZV) after SOT is rare and most commonly seen in the paediatric transplant population because of VZV epidemiology. Zoster occurs in 5-15% of patients, usually after the sixth post-transplant month. Prophylactic regimens for zoster are neither practical nor cost effective after SOT because of the late onset of disease and low proportion of affected individuals. All SOT recipients should receive VZV immune globulin after contact with either varicella or zoster. Epstein-Barr virus has its most significant effect in SOT as the precipitating factor in the development of post-transplant lymphoproliferative disorders. Antiviral agents that could be effective are the same as those used for CMV, but indications for and effectiveness of prophylaxis are poorly established. Hepatitis B virus (HBV) and hepatitis C virus (HCV) are important pathogens in the SOT population as indications for transplantation. So-called 'prophylaxis' for recurrent HBV and HCV after liver transplantation is controversial, suppressive rather than preventive, and potentially lifelong. Influenza infection after SOT is acquired by person-to-person contact. During epidemic periods of influenza, transplant populations experience a relatively high frequency of infection, and influenza may affect immunosuppressed SOT recipients more adversely than immunocompetent individuals. Antiviral medications for prevention of influenza are administered as post-exposure prophylaxis to SOT Aggrenox Capsule recipients, in addition to yearly vaccine, in circumstances such as influenza epidemics and nosocomial outbreaks, and after exposure to a symptomatic individual during 'flu season'.

Famciclovir was well tolerated, with a safety profile similar to that of placebo. Famciclovir accelerated lesion healing and reduced the duration of viral shedding. Most importantly, famciclovir recipients had faster resolution of postherpetic Avapro Brand neuralgia (approximately twofold faster) than placebo recipients; differences between the placebo group and both the 500-mg famciclovir group (hazard ratio, 1.7 [95% CI, 1.1 to 2.7]) and the 750-mg famciclovir group (hazard ratio, 1.9 [CI, 1.2 to 2.9]) were statistically significant (P = 0.02 and 0.01, respectively). The median duration of postherpetic neuralgia was reduced by approximately 2 months.
