Reactivation of chronic hepatitis B viral infection causes significant morbidity and mortality after bone marrow transplantation. Recently, nucleoside analogues, such as famciclovir, were found to have a direct suppressive effect on hepatitis B virus replication in both in vitro and in vivo studies. We have studied the effect of famciclovir on the incidence of hepatitis B virus reactivation and hepatitis after allogeneic bone marrow transplantation.

Famciclovir is a guanine analog antiviral drug used commonly for herpes zoster. Efficacy of famciclovir treatment has been reported to be comparable to valacyclovir treatment. Both of these medications reduce the time to complete cessation of zoster-associated pain including post-herpetic neuralgia, as compared to acyclovir. We conducted a multicenter, randomized, open clinical trial in order to evaluate the extent of pain relief afforded by these two antiviral drugs during the acute disease phase of herpes zoster. The study group comprised 86 immunocompetent adult patients suffering from herpes zoster, who were treated with either famciclovir or valacyclovir for 7 days. Of these, 55 patients enrolled in this study within 72 h of the onset of the rash and 31 patients after 72 h of the onset. There was a significant reduction in acute herpes zoster pain with famciclovir on day 7 and at 2-3 weeks in both of these patient groups, while with valacyclovir, there was not significant reduction in pain on day 7. Of patients aged 50 years or older, there was a significantly earlier reduction in pain with famciclovir than with valacyclovir. In addition, a significant reduction in the number of patients with pain was observed as early as days 3-4 with famciclovir treatment as compared with valacyclovir treatment. We conclude that famciclovir was superior to valacyclovir in the relief of acute pain of herpes zoster. Accordingly, famciclovir is recommended for herpes zoster patients with moderate symptoms and a visual analog scale score of under 50 mm.

Virological analysis revealed that the pre-treatment dominant HBV quasispecies in the patient had a number of non-consensus genotype B mutations which were located in the basal core promoter (BCP), polymerase, X, core and S genes. Subsequent to the instigation of antiviral therapy, the dominant drug resistant HBV which caused virological breakthrough and was associated with hepatic failure displayed a series of unique mutations particularly in the BCP (A1762T and G1764A) and in the polymerase (rtL180M, rtM204V, rtA222T and rtL336V), core (cP5T, cS26A, cV85I and cP135A), surface (sI195M and sM213I) and X (xK95Q, xN118T, xK130M and xV131I) proteins.

Herpes zoster occurs rarely in immunocompetent children and infrequently in immunocompetent young adults. However, its incidence increases with age, particularly after age 50. Reactivation of varicella-zoster virus (VZV) is characterized by a rash and is generally accompanied by considerable pain, dysesthesias, and skin hypersensitivity. Chronic pain that is sometimes experienced after the rash has healed is referred to as postherpetic neuralgia (PHN), the most common complication of herpes zoster. Postherpetic neuralgia is often severe and, unfortunately, refractory to most forms of treatment. The incidence of PHN also increases dramatically with increased age. More than 50% of zoster patients over 60 years old will develop PHN, which may persist for months and even years. Thus, established PHN is difficult to manage, often causing serious morbidity, depression, and high costs in terms of consumption of healthcare resources. Currently, early antiviral treatment with famciclovir has shown promise of reducing the duration of PHN.

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.

We report two Chinese patients in whom lamivudine treatment resulted in HBsAg seroclearance. One patient received lamivudine, and another patient received 12-week famciclovir treatment followed by lamivudine. Lamivudine was maintained after HBeAg seroconversion. These two patients lost HBsAg at 24 and 27 months (ages, 23 and 19.3 years, respectively) and developed measurable titer of anti-HBs after 65 and 71 months of therapy, respectively. The liver biochemistry was normal after HBeAg seroconversion. The serum hepatitis B virus (HBV) DNA levels were undetectable (<200 copies/ml) both at the time of HBeAg seroconversion and at the last follow-up. Liver biopsy of one patient showed nearly normal histology, with undetectable intrahepatic total HBV DNA and covalently closed circular DNA. In conclusion, lamivudine therapy can result in HBsAg seroclearance at an early age even though the phenomenon is rare.

CMV and varicella zoster virus (VZV) are significant causes of morbidity and mortality following umbilical cord blood transplantation (UCBT). However, the kinetics of reconstitution and protective potential of antiviral cell-mediated immune responses following UCBT remain poorly characterized. In this study, the reconstitution of CMV- and VZV-specific T cell responses was assessed using IFN-γ ELISPOT in 28 children who underwent UCBT to treat hematological or inherited disorders. Barely detectable in the first 3 mo posttransplantation, CMV- and VZV-specific T cell responses were observed in 30.4% and 40.3% of study subjects after 36 mo of follow-up. Four of five CMV-seropositive subjects developed detectable levels of circulating CMV DNA (DNAemia), and 5 of 17 VZV-seropositive patients experienced herpes zoster during the posttransplant period. Four CMV-seronegative subjects developed IFN-γ responses against CMV, and four subjects developed a VZV-specific IFN-γ response without clinical signs of infection. No CMV- or VZV-related events were observed in study subjects following the development of CMV- or VZV-specific responses > 150 spot-forming units/10(6) PBMCs, consistent with T cell-mediated protection. Finally, famciclovir prophylaxis did not strictly prevent the reconstitution of the VZV-specific T cell repertoire, because the frequency of T cells producing IFN-γ in response to VZV Ags reached levels consistent with protection in two nonzoster subjects. Monitoring of CMV- and VZV-specific cell-mediated immunity could inform immunocompetence and guide the initiation and cessation of antiherpetic prophylaxis in UCBT recipients.

We conducted a randomized, placebo-controlled clinical study evaluating famciclovir (500 mg 3 times daily and 1.5 g once daily) for 1 year (6 months post-treatment follow-up) in patients with chronic hepatitis B e antigen (HBeAg)-positive hepatitis B virus (HBV) infection. The study was conducted in 80 centers in North America, Europe, and Australia/New Zealand. A total of 417 patients with histologically documented chronic hepatitis B (histologic activity index [HAI] 9.5-11.0) received famciclovir (500 mg 3 times daily or 1.5 g once daily) or placebo. Famciclovir 500 mg 3 times daily significantly reduced HBV DNA and median HAI scores versus placebo. By week 8, median HBV DNA decreased from 1,645 to 283 MEq/mL (famciclovir 500 mg 3 times daily) and from 1,147 to 304 MEq/mL (famciclovir 1.5 g once daily), while increasing for placebo (1,617 to 1,685 MEq/mL). Median change in HBV DNA at the end of therapy was -76% (famciclovir 500 mg 3 times daily; P <.01) and -60% (famciclovir 1.5 g once daily; P =.25) versus -37% for placebo. Median change in HAI was -1.5 points (famciclovir 500 mg 3 times daily; P =.02) and -1.0 point (famciclovir 1.5 g once daily; P =.35) and zero for placebo. Fifty percent of patients receiving famciclovir 500 mg 3 times daily (P =.07) and 43% receiving 1.5 g once daily (P =.41) experienced >/=2 points improvement in HAI versus 37% for placebo. Nine percent of patients treated with famciclovir 500 mg 3 times daily underwent anti-HBeAg seroconversion with undetectable HBV DNA at end of follow-up versus 3% in the placebo group (P =.05). Famciclovir was well tolerated; the incidence of post-treatment alanine transaminase (ALT) elevations was comparable with placebo. In conclusion, famciclovir 500 mg 3 times daily gave modest suppression of viral replication, but translated into significant histologic improvement in median HAI score at 1 year.

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. herpes simplex virus type 1 (HSV-1), and type 2 (HSV-2), varicella-zoster virus (VZV) and/or human cytomegalovirus (HCMV)] infections. In recent years, several new guanosine analogues have been developed, including the 3-membered cyclopropylmethyl and -methenyl derivatives (A-5021 and synguanol) and the 6-membered D- and L-cyclohexenyl derivatives. The activity of the acyclic/carbocyclic guanosine analogues has been determined against a wide spectrum of viruses, including the HSV-1, HSV-2, VZV, HCMV, and also human herpesviruses type 6 (HHV-6), type 7 (HHV-7) and type 8 (HHV-8), and hepatitis B virus (HBV). The new guanosine analogues (i.e. A-5021 and D- and L-cyclohexenyl G) were found to be particularly active against those viruses (HSV-1, HSV-2, VZV) that encode for a specific thymidine kinase (TK), suggesting that their antiviral activity (at least partially) depends on phosphorylation by the virus-induced TK. Marked antiviral activity was also noted with A-5021 against HHV-6 and with D- and L-cyclohexenyl G against HCMV and HBV. The antiviral activity of the acyclic/carbocyclic nucleoside analogues could be markedly potentiated by mycophenolic acid, a potent inhibitor of inosine 5'-monophosphate (IMP) dehydrogenase. The new carbocyclic guanosine analogues (i.e. A-5021 and D- and L-cyclohexenyl G) hold great promise, not only as antiviral agents for the treatment of herpesvirus infections, but also an antitumor agents for the combined gene therapy/chemotherapy of cancer, provided that (part of) the tumor cells have been transduced by the viral (HSV-1, VZV) TK gene.

None of the patients had a complete biochemical response, with a near complete normalization of ALT levels being observed in 3/6 patients. There was a lack of correlation between virological and biochemical responses. None of the patients seroconverted to anti-HBs or anti-HBe. A virological clearance was observed in only two patients, whereas a moderate reduction in HBV DNA levels was present in one. HBV DNA levels were higher than levels during pretreatment in the three remaining patients. Histological improvement was only observed in one patient.

Genital herpes is among the most prevalent sexually transmitted diseases. Optimal management of genital herpes includes accurate diagnosis, antiviral therapy, and counseling of patients about complications and transmission of herpes simplex virus (HSV). Antiviral therapy offers significant palliation, and the option of episodic or suppressive treatment should be offered to all patients with genital herpes. Valacyclovir and famciclovir are two newer antiviral agents that are effective and safe for the treatment of genital herpes. Prevention strategies for sexual and perinatal transmission of HSV have not been well defined. Availability of type-specific serological tests for HSV antibodies may assist in identifying persons at risk for acquiring or transmitting HSV infection. Further research is needed to define strategies to prevent the spread of this epidemic infection.

The amino acid ester derivatives of 6-deoxypenciclovir, 11-20, were synthesized as potential prodrugs of penciclovir, and were evaluated for their oral penciclovir bioavailability in mice and rats. Esterification of 6-deoxypenciclovir with N-carbobenzyl-oxyglycine, -L-alanine, -L-valine, -L-leucine, or -L-isoleucine (3.75equiv.) using conventional coupling method (DCC/DMAP) afforded the mono-O-ester derivatives 1-5 in 47-55% yields as a mixture of two diastereomers along with the di-O-ester derivatives 6-10 in 20-29% yields. Reductive cleavage of carbobenzyloxy (Cbz) group (10% Pd/C, 1 atmosphere of H2, room temperature in methanol) followed by subsequent treatment of the resulting free amine with methanolic HCI solution provided the mono-O-ester derivatives 11-15 as di-HCl salt in 51-98% yields and the di-O-ester derivatives 16-20 as tri-HCl salt in 65 98% yields. Of the prodrugs tested in mice and rats, 6-deoxypenciclovir O-L-valinate (13), O-L-isoleucinate (15), and O,O-di-glycinate (16) showed significantly higher urinary recovery of penciclovir compared with that of penciclovir, but those are somewhat lower than that of famciclovir.

famvir 750 mg 2016-12-17

Until recently aciclovir has been the only licensed drug for the treatment of herpes zoster. A number of new drugs have emerged over the past few years which offered the potential for improved efficacy or ease of administration. With the completion of the first efficacy trials for each of these agents it has become apparent that, whilst less frequent dosing can he accomplished, it is not easy to significantly improve on the efficacy of aciclovir. Increasing age, the presence of prodromal pain and more severe pain at presentation have, however, been found to predispose to a longer duration of pain. Taking cessation of pain as the single most important parameter, at least buy famvir for the older immunocompetent population as a whole, only valaciclovir has, to date, been shown to be superior to standard therapy with aciclovir. This review utilises primarily intent-to-treat data to illustrate the relative efficacy of the different therapies.

After several nucleoside analogues have been tested against chronic hepatitis B virus (HBV) infection with minimal success, lamivudine seems to be a highly effective new therapeutic option. This review focuses on nucleoside buy famvir metabolism and on the molecular action of lamivudine as well as on results of clinical studies for several indications. We report on results of trials on the use of lamivudine for chronic HBV infection, chronic HBV under immunosuppression and prophylaxis or treatment of HBV reinfection before or after orthotopic liver transplantation. Aspects of combination therapy of different nucleoside analogues as well as on combination of lamivudine with interferon are also highlighted. Although lamivudine seems to be highly effective in most patients at the start of therapy, development of resistance by mutations in the viral polymerase is a significant clinical problem. The mode of resistance development is compared with the situation in HIV infection. Possible cross-resistance with other nucleoside analogues and the perspectives of lamivudine therapy are also considered.

Although vidarabine was the first systemic antiviral drug for the treatment of acute herpes zoster, the agent now used most buy famvir frequently is acyclovir, a far safer drug that became available a decade ago. However, even with widespread use of acyclovir, postherpetic neuralgia (PHN) remains a principal cause of postinfectious morbidity. Newer antiviral agents, such as famciclovir and valacyclovir, have recently been introduced for the treatment of uncomplicated herpes zoster. In a double-blind, randomized study, 500 mg of famciclovir three times daily for 7 days was compared with placebo; in a second study, 500 mg of famciclovir three times daily for 7 days was compared with 800 mg of acyclovir five times daily for 7 days. Famciclovir significantly reduced duration of viral shedding (P = 0.0001) and accelerated lesion resolution compared with placebo. Famciclovir was comparable to acyclovir for these acute parameters. Most importantly, famciclovir recipients lost PHN two times faster than those receiving placebo (P = 0.02 all patients; P = 0.004 patients > or = 50 years) resulting in a reduction in the median duration of PHN (56 days all patients; 100 days patients > or = 50 years). This reduction translated to a 3.5-month reduction in the median duration of PHN for patients 50 years or older, those at greatest risk for developing the most common complication of herpes zoster. Famciclovir 500 mg administered three times a day for 7 days is an effective and well-tolerated treatment for acute herpes zoster, and is the only oral antiviral agent proven to reduce the duration of PHN when administered during acute zoster infection.

Liver transplantation in hepatitis B virus (HBV)-infected patients is very commonly followed by recurrence of infection in the transplanted liver. Most recipients with HBV recurrence will develop chronic hepatitis that follows a more aggressive course than is seen in non-immuno-compromized subjects and this frequently results in graft failure. The presence of hepatitis B e antigen or significant levels of HBV-DNA in the serum is highly predictive of recurrence and this has led to the view that patients, whose serum is positive for these conventional markers of replication, should be excluded from transplantation. The key to improving the results of transplantation in patients with HBV infection lies in the development of effective strategies to prevent reinfection. High dose anti-HBs immunoglobulin is effective in patients who are coinfected with hepatitis D, those transplanted for fulminant hepatitis and cirrhotic patients who have very low levels of viral replication prior to transplantation. Unfortunately, immunoprophylaxis does not seem to influence the outcome in those patients with higher levels of replication. There are several new orally active nucleoside analogues that and potent inhibitors of hepatitis B replication that may be effective for both the prevention and treatment of recurrent disease. The most promising are lamivudine (2',3',dideoxy,3',thiacytidine) and famciclovir (a guanosine analogue). Both agents have been extensively evaluated in animal models of HBV and have been shown to rapidly suppress viral replication. The initial experience with these agents in liver transplant recipients has been promising and a number of studies are currently underway to determine whether these drugs, buy famvir used alone or in combination with immunoprophylaxis, are able to prevent recurrence in those patients at highest risk of post-transplant HBV recurrence.

Although herpes zoster (shingles) can occur in anyone with a history of chickenpox, it is more prevalent and usually more severe in older patients (i.e. persons over 50 years of age). While the cutaneous manifestations of shingles usually resolve in approximately 4 weeks, the pain can persist for several months, or even years in the untreated patient. This pain following healing of the skin, termed post-herpetic neuralgia (PHN), can be very severe. Three well tolerated and effective antiviral drugs are available for the therapy of acute herpes zoster. The nucleoside analogues, aciclovir, famciclovir and valaciclovir, appear to shorten the duration of PHN to a similar degree, but none affects the incidence of PHN. Aciclovir is taken 5 times daily for 7 days, while famciclovir is taken 3 times daily for 7 days. Valaciclovir, the L-valyl ester of aciclovir, when taken orally, produces plasma levels of aciclovir equivalent to those seen following intravenous administration of aciclovir. Valaciclovir has not only been proved to be more efficient than aciclovir (i.e. 3 times daily administration) but also more effective than aciclovir in shortening the duration of PHN. Current studies are determining the relative efficacy of valaciclovir versus famciclovir. Presently, a fourth drug, sorivudine, is being compared with aciclovir for the therapy of acute herpes zoster in older patients, but data from these trials are not yet available. Corticosteroids have been used to treat herpes zoster for much longer than the antiviral drugs, but the effect of corticosteroids on PHN does not appear to be consistent. Corticosteroids plus aciclovir did not provide an added benefit over aciclovir alone in one study but this combination did appear to improve the buy famvir quality of life of older patients in another investigation. The recent availability of the varicella zoster vaccine may cause shingles to be an uncommon and/or mild disease by the mid twenty-first century. Meanwhile, the search continues for more effective and efficient therapies for acute herpes zoster with the primary goal in older patients to affect the most important sequela of zoster in this population, PHN.

Famciclovir is a novel guanosine nucleoside analogue with activity against herpes viruses and hepatitis B virus (HBV). Several preliminary reports have described efficacy of famciclovir in patients with recurrent hepatitis B after orthotopic liver transplantation (OLT). This report describes the largest study to date of long-term famciclovir treatment in patients with de novo or recurrent hepatitis B post-OLT. One hundred thirty patients with detectable serum HBV DNA after OLT received oral famciclovir 500 mg tid on a compassionate-use basis. Safety analyses included all treated patients; efficacy was assessed in all patients and a subgroup of 73 patients with complete baseline HBV DNA and alanine aminotransferase (ALT) data who had received > or =6 months of treatment. Efficacy parameters included serum levels of HBV DNA, ALT, and anti-HBe or anti-HBs seroconversion rates. Of the 70 patients treated for > or =6 months who could be evaluated for response/non-response to famciclovir, 52 (74%) were responders, defined as patients who experienced a 70% decrease or more in HBV DNA levels from baseline, or who became HBV DNA-negative, for at least two consecutive visits. In famciclovir responders, HBV DNA levels decreased by a median of 91% after 12 weeks of treatment, 95% after 6 months and >99% after 18 months of treatment. Marked differentiation between responders and non- buy famvir responders could be made soon after the onset of treatment. Among anti-HBe positive patients with evidence of HBV replication, 12/13 were responders. Patients with high baseline ALT levels experienced more rapid suppression of HBV DNA during therapy with famciclovir. Famciclovir therapy was safe and well tolerated; serious adverse events were reported infrequently. Famciclovir treatment may be beneficial in patients with hepatitis B infection post-OLT.

Development of serologic assays to detect antibodies to herpes simplex virus (HSV) glycoproteins (g)G1 and (g)G2 has allowed accurate definition of the seroprevalence of HSV-2 worldwide. Studies from all continents indicate epidemic proportions of HSV-2 infection. In the United States, 1 in 5 sexually active adults is infected. In Africa and the Caribbean, HSV prevalence is higher. Since the development of the acyclic nucleoside derivatives acyclovir, famciclovir, and valacyclovir, treatment of mucocutaneous HSV is a practice of everyday medical care. Yet, despite effective drugs, there is widespread discontent by clients and providers about care of patients with genital herpes. Much of this relates Priligy Buy Uk to transmission complexities and the varied natural history of the infection. However, over time, most patients adjust to their disease and the medical and psychosocial complications. Recent studies show condoms reduce transmission, providing an important tool for counseling the patient with newly diagnosed genital herpes.

Famciclovir reduced genital and oral HSV shedding from 11.4% of days during the placebo period to 4.7% of days during famciclovir therapy. The reduction was greater in participants with a history of genital herpes (74%) than in those without such a history (30%). In multivariate analyses, famciclovir protected against total (clinical and subclinical) genital shedding among persons with a clinical history of genital herpes (RR, 0.23; 95% CI, 0.15-0.35; P < 0.001 Tegretol Brand Name ). Among HSV-2 seropositive participants without a history of genital herpes, 60% had HSV detected in the genital area at least once during the study. Famciclovir therapy did not result in a statistically significant reduction in total HSV shedding in participants without a history of genital herpes.

This Commentary is dedicated to the memory Mobic Generic of Dr. Jacques Gielen, the late Editor of Biochemical Pharmacology, whom I have known as both an author and reviewer for the Journal for about 25 years. This is, quite incidentally, about the time it took for bringing brivudin (BVDU) [(E)-5-(2-bromovinyl)-2'-deoxyuridine] from its original description as an antiviral agent to the market place (in a number of European countries, including Germany and Italy) for the treatment of herpes zoster in immunocompetent persons. BVDU is exquisitely active and selective against varicella-zoster virus (VZV) and herpes simplex virus type 1 (HSV-1). BVDU owes this high selectivity and activity profile to a specific phosphorylation by the virus-encoded thymidine kinase, followed by a potent interaction with the viral DNA polymerase. The (E)-5-(2-bromovinyl)-substituent can be considered as the hallmark for the activity of BVDU against VZV and HSV-1. Extensive clinical studies have indicated that BVDU as a single (oral) daily dose of 125 mg (for no more than 7 days) is effective in the treatment of herpes zoster, as regards both short-term (suppression of new lesion formation) and long-term effects (prevention of post-herpetic neuralgia). In this sense, BVDU is as efficient and/or convenient, if not more so, than the other drugs (acyclovir, valaciclovir, famciclovir) that have been licensed for the treatment of herpes zoster. There is one caveat; however, BVDU should not be given to patients under 5-fluorouracil therapy, as the degradation product of BVDU, namely (E)-5-(2-bromovinyl)uracil (BVU), may potentiate the toxicity of 5-fluorouracil, due to inhibition of dihydropyrimidine dehydrogenase, the enzyme involved in the catabolism of 5-fluorouracil.

Patients have been treated with Famciclovir for a median of 14 months. Hepatitis B virus replication and biochemical parameters were regularly tested and liver biopsies were taken before treatment and after a median time of 7 months. HBV-polymerase was sequenced in all Mysoline 30 Tablet patients before therapy and in those patients who experienced virological breakthrough.

This study showed similar efficacy and tolerability of 1-day treatment with famciclovir 1000 mg twice-daily compared to placebo in immunocompetent Black adults with RGH. Famciclovir has proven efficacy and safety in the overall RGH population. Further understanding of the efficacy of antiherpes therapy in Black patients with recurrent genital herpes may be warranted.

In our previous study, we concluded that an epidural blockade combined with intravenous acyclovir is very effective in treating the acute pain in herpes zoster and postherpetic neuralgia. We evaluated the efficacy of oral famciclovir and epidural blockade on the pain of herpes zoster, compared to acyclovir administered intravenously and epidural blockade. For this purpose, we examined a new group treated with famciclovir and epidural blockade to compare with the group treated with acyclovir and epidural blockade in our previously study. The changes in the intensity of pain, the number of days required for relief of pain, and the total duration of pain were checked. We compared the days required for relief of pain (DRP) and the total duration of pain (TDP) of this group with those of the previous studied group treated with acyclovir and epidural blockade. DRP was significantly less, but TDP was similar. DRP and TDP were significantly lower, if the patients were treated within 7 days of symptom onset. The patients had a shorter DRP regardless of pain type than the previously studied group treated with acycolvir and epidural blockade. For the severe and moderate pain grades, there was a shorter DRP from 100 to 10. TDP was not significantly different for the groups regardless of pain type or grade. We believe that famciclovir and epidural blockade are very effective in treating the pain of herpes zoster, with a view to shortening the period of acute pain, providing similar effects on the prevention of postherpetic neuralgia, and being convenient to administer, compared to intravenous acyclovir and epidural blockade in our previous study.
