Spongouridine Description
Vidarabine or 9-β-D-arabinofuranosyladenine (ara-A) is an antiviral drug which is active against herpes simplex and varicella zoster viruses.

Clinical indication
Vidarabine is an antiviral, active against herpes viruses, poxviruses, rhabdoviruses, hepadnaviruses and some RNA tumour viruses. A 3% ophthalmic ointment Vira-A is used in the treatment of acute keratoconjunctivitis and recurrent superficial keratitis caused by HSV-1 and HSV-2. Vidarabine is also used to treat herpes zoster in AIDS patients, reducing lesions formation and the duration of viral shedding. Many of the previous uses of vidarabine have been superseded by acyclovir, due to the hospitalisation required for intra venous dosing, and acyclovir has a higher selectivity, lower inhibitory concentration and higher potency. Toxic side effects are rare, but have been reported with high concentrations of vidarabine, such as nausea, vomiting, leukopenia and thrombocytopenia in patients receiving high intravenous doses daily.
