To assess the cost-effect relationship of aciclovir prophylaxis versus early treatment, we performed a retrospective study in 44 allogeneic bone marrow transplant recipients, who had only received aciclovir for therapeutic purposes. After bone marrow transplantation 18 herpes simplex infections occurred in 15 of the 33 patients who were seropositive for herpes simplex virus. In ten patients wit...

OBJECTIVE To compare the efficacy and safety of twice daily valaciclovir with five times daily aciclovir in the treatment of an episode of recurrent genital herpes simplex virus (HSV) infection in immunocompetent individuals. METHODS 739 patients with a history of recurrent genital HSV infection received either oral valaciclovir (500 mg twice daily) or aciclovir (200 mg five times daily) for ...

Treatment of adult chickenpox with aciclovir is controversial because of the relatively high cost of medication and small proven benefits of therapy. A decision-tree model was used to estimate the cost effectiveness of aciclovir, from third-party payer and societal perspectives: the incremental cost per quality-adjusted life-year (QALY) gained was calculated for aciclovir treatment of chickenpo...

OBJECTIVES Systemic aciclovir and its prodrug valaciclovir are effective in treating and reducing recurrences of genital herpes simplex virus (HSV) and reducing transmission. Local aciclovir delivery, if it can achieve and maintain comparable intracellular genital tract levels, may be equally effective in the treatment and suppression of genital HSV. Intravaginal ring (IVR) delivery of aciclovi...

OBJECTIVES To estimate the extent of aciclovir refractory herpes simplex virus (HSV) infection in HIV coinfected patients in the United Kingdom and survey clinicians on their approaches to its management. DESIGN Questionnaire survey of representative sample of one third of United Kingdom HIV physicians. MAIN OUTCOME MEASURES Use of antiviral therapies for genital HSV infections in HIV posit...

with obstructive airway diseases. It is well known that theophylline has a narrow therapeutic range being a plasma concentration of 10—20 mg/ml and is extensively metabolized in humans. Many articles have been published on the drug interactions of theophylline with other coadministered drugs mediated by cytochrome P450 (CYP) 1A2, which is the major metabolizing enzyme for theophylline. For exam...

OBJECTIVE To determine whether oral prednisolone or aciclovir, used separately or in combination, early in the course of Bell's palsy, improves the chances of recovery at 3 and 9 months. DESIGN A 2 x 2 factorial randomised double-blind trial. Patients were randomly assigned to treatment by an automated telephone service using a permuted block randomisation technique with block sizes of four o...

Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing (biowaiver) for the approval of immediate release (IR) solid oral dosage forms containing aciclovir are reviewed. Aciclovir therapeutic use and therapeutic index, pharmacokinetic properties, data related to the possibility of excipient interactions and reported BE/bioavailability (BA) studies were ...

This report is concerned with the capacities of aciclovir to protect mice challenged intracerebrally with multiple lethal doses of type 1 herpes simplex virus and to control multiplication of this virus in the brain. With treatment initiated 12 h after inoculation and continued for 4 consecutive days, aciclovir administered subcutaneously in daily doses ranging from 40 to 100 mg/kg led to 21-da...

OBJECTIVE Herpes simplex virus encephalitis (HSVE) is associated with significant morbidity and mortality, even with appropriate antiviral therapy. In the present investigation, the first to assess efficacy of corticosteroid treatment with aciclovir therapy in HSVE, multiple logistic regression analysis was performed of predictors of outcome in adult patients with HSVE. METHODS A non-randomis...
