Vidarabine monohydrate
Based on 7 publication(s) in Google Scholar
Vidarabine monohydrate is a Purine nucleoside derivative and Antiviral agent. The triphosphate derivative of Vidarabine monohydrate competitively inhibits DNA polymerase, incorporates into the terminus of elongating DNA molecules, and interferes with the early steps of viral DNA synthesis. Vidarabine monohydrate inhibits the replication of herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein-Barr virus and vaccinia virus, reduces viral shedding, and accelerates skin healing. Vidarabine monohydrate is metabolized to arabinosyl hypoxanthine, causes minimal impairment of corneal wound healing in rabbit models, and is associated with recurrence of herpes simplex encephalitis. Vidarabine monohydrate can be used in the research of herpetic keratoconjunctivitis, herpes simplex encephalitis, herpetic uveitis, and chronic active hepatitis associated with hepatitis B virus.

Biological Activity
Vidarabine monohydrate inhibits herpes simplex virus, varicella-zoster virus, and cytomegalovirus in in vitro cell culture systems[1].
Vidarabine monohydrate exerts its antiviral effect via phosphorylation to a triphosphate derivative that competitively inhibits DNA polymerase and is incorporated into terminal positions of growing DNA molecules[1].

Result:Achieved complete healing of 5 mm corneal lesions by 60 hours, with no significant difference in healing rate compared to placebo or idoxuridine.
Achieved complete healing of 10 mm corneal lesions by 8 days, with no significant difference in healing rate compared to placebo or idoxuridine.
Showed significantly better regenerated epithelium quality (lower scores) than idoxuridine-treated eyes on days 4 and 7 (p = 0.05), with results comparable to placebo.
Demonstrated less severe histological abnormalities compared to idoxuridine-treated eyes.
