Antivirals are used to treat herpes. Valacyclovir Valtrex, acyclovir Zovirax, and famciclovir Famvir are the most common of them. Despite their assumed similarity, valacyclovir and acyclovir have several differences. Valacyclovir works by inhibiting viral DNA replication. The drug is available as an oral tablet in two strengths — mg and 1,mg.

Aciclovir has poor oral bioavailability and the absorbed drug is reached in good concentrations in breast milk, amniotic fluid and the placenta. Aciclovir is an acyclic purine nucleoside. Its antiviral activity depends upon intracellular phosphorylation to its triphosphate derivative. Because of its higher affinity for viral thymidine kinase, aciclovir is phosphorylated at a much higher rate by the viral enzyme.

Valaciclovir, also spelled valacyclovir, is an antiviral medication used to treat outbreaks of herpes simplex or herpes zoster shingles. Common side effects include headache and vomiting. Valaciclovir was patented in and came into medical use in Bell's palsy does not seem to benefit from using valaciclovir as its only treatment.

H erpes simplex and herpes zoster viruses can have many ocular manifestations, some of which are serious and vision-threatening. Both conditions have the potential to be chronic and recurrent, as well. Cornea specialist Francis Mah, in practice in La Jolla, California, notes that the live virus can cause epithelial keratitis and other ocular manifestations. The treatment for this is epithelial scraping with an instrument such as a Kimura spatula, along with trifluridine drops—which was a huge advance at the time they were introduced—and oral antivirals, such as acyclovir, valacyclovir and famciclovir, the most commonly used treatments among cornea specialists. A newer agent, ganciclovir gel, is also an option.

To avoid excessive dosage in obese patients, dose should be calculated on the basis of ideal weight for zovirax 1000mg. UKHSA advises aciclovir is used for post-exposure prophylaxis of varicella zoster infection, but it is not licensed for this indication. Elderly risk of neurological reactions ; maintain adequate hydration especially with infusion or high doses.

Each mg vial contains sodium ion approximately 26 mg. When reconstituted as directed, Zovirax IV for infusion has a pH of approximately Pharmacotherapeutic Group: Antiviral agent. Pharmacodynamic Effects: Prolonged or repeated courses of acyclovir in severely immuno-compromised individuals may result in the selection of virus strains with reduced sensitivity, which may not respond to continued acyclovir treatment. In vitro exposure of HSV isolates to acyclovir can also lead to the emergence of less sensitive strains.

The relationship between the in vitro -determined sensitivity of HSV isolates and clinical response to acyclovir therapy is not clear. All patients should be cautioned to ensure they avoid the potential of virus transmission, particularly when active lesions are present. The corresponding trough plasma levels C ssmin levels 7 hours later were 2. Tablet: Acyclovir is only partially absorbed from the gut. Elimination: In adults, the terminal plasma half-life of acyclovir after administration of IV acyclovir is about 2.

Most of the drug is excreted unchanged by the kidney. Renal clearance of acyclovir is substantially greater than creatinine clearance, indicating that tubular secretion in addition to glomerular filtration contributes to the renal elimination of the drug. Special Patient Populations: In patients with chronic renal failure, the mean terminal half-life was found to be The mean acyclovir half-life during hemodialysis was 5.

In the elderly, total body clearance falls with increasing age associated with decreases in creatinine clearance, although there is little change in the terminal plasma half-life. Toxicology: Preclinical Safety Data: The results of a wide range of mutagenicity tests in vitro and in vivo indicate that acyclovir does not pose a genetic risk to man. Acyclovir was not carcinogenic in long-term studies in the rat and the mouse.

Systemic administration of acyclovir in internationally accepted standard tests did not produce embryotoxic or teratogenic effects in rabbits, rats or mice. The clinical relevance of these findings is uncertain. In addition, oral Acyclovir Zovirax provided effective prophylaxis for herpes virus disease. Injection: Acyclovir Zovirax IV for infusion is indicated for the treatment of herpes simplex infections, prophylaxis of herpes simplex infections in immune-compromised patients, treatment of varicella zoster infections, herpes simplex infections in the neonate.

Tablet: Adults: Treatment of Herpes Simplex: For treatment of herpes simplex infections, mg Acyclovir Zovirax should be taken five times daily at approximately four-hourly intervals omitting the night time dose. Treatment should continue for five days but in severe initial infections may have to be extended. In severely immune-compromised patients e.

Dosing should begin as early as possible after the start of an infection; for recurrent episodes this should preferably be during the prodromal period or when lesions first appear.

Background and objectives: Valaciclovir, the L-valine ester prodrug of acyclovir, is much better absorbed than acyclovir and produces acyclovir exposures three to five times those attainable with the parent drug. Goals: To determine whether the improved bioavailability of valaciclovir and a more convenient, less frequent dose regimen can maintain the clinical efficacy previously demonstrated for acyclovir. Blood for herpes serology tests was obtained on days 1 and 14; hematology and chemistry toxicity screening was done on days 1 and 7. Results: Valaciclovir and acyclovir did not differ significantly in efficacy with respect to duration of viral shedding hazard ratio, 1. Adverse experiences were generally infrequent and mild and were comparable in the two treatment groups.
