Description
Curator's Comment:: https://www.ncbi.nlm.nih.gov/pubmed/6313598 | https://www.ncbi.nlm.nih.gov/pubmed/2828440 | https://www.ncbi.nlm.nih.gov/pubmed/202961

Acyclovir is a synthetic antiviral nucleoside analogue. A screening program for antiviral drugs begun at Burroughs Wellcome in the 1960s resulted in the discovery of acyclovir in 1974. Preclinical investigation brought the drug to clinical trials in 1977 and the first form of the drug (topical) was available to physicians in 1982. Activity of acyclovir is greatest against herpes 1 and herpes 2, less against varicella zoster, still less against Epstein-Barr, and very little against cytomegalovirus. Acyclovir is an antiviral agent only after it is phosphorylated in infected cells by a viral-induced thymidine kinase. Acyclovir monophosphate is phosphorylated to diphosphate and triphosphate forms by cellular enzymes in the infected host cell where the drug is concentrated. Acyclovir triphosphate inactivates viral deoxyribonucleic acid polymerase.

CNS Activity

Curator's Comment:: Valacyclovir hydrochloride is rapidly converted to acyclovir which was detected in CSF after oral administration of valacyclovir.

Sample Use Guides

Valacyclovir may be given without regard to meals. Cold Sores (Herpes Labialis): The recommended dosage of Valacyclovir for treatment of cold sores is 2 grams twice daily for 1 day taken 12 hours apart. Therapy should be initiated at the earliest symptom of a cold sore. Genital Herpes: Initial Episode: The recommended dosage of Valacyclovir for treatment of initial genital herpes is 1 gram twice daily for 10 days. Therapy was most effective when administered within 48 hours of the onset of signs and symptoms. Recurrent Episodes: The recommended dosage of Valacyclovir for treatment of recurrent genital herpes is 500 mg twice daily for 3 days. Initiate treatment at the first sign or symptom of an episode.
Route of Administration: Oral
In uptake studies using valacyclovir, the extraction solution (water/methanol, 50:50) was added to the Caco-2 cells after the uptake period. After standing for 1 h at room temperature, the solutions were centrifuged and the supernatants were filtered. The filtrate was analyzed by highperformance liquid chromatography (HPLC). Valacyclovir showed a marked inhibitory effect (K=440 +/- 29mkM) on [14C]glycylsarcosine uptake via the apical PEPT1.
