Drug Mode of Action ::
Ribavirin is a synthetic nucleoside which has inhibitory action against respiratory syncytial virus, influenza virus and herpes simplex virus. The mechanism of action is not clear. It may act at several sites including cellular enzymes to interfere with viral nucleic acid synthesis. The mono- and triphosphate derivatives are known to be responsible for the antiviral action of the compound.
Drug Interactions ::
May worsen neutropenia induced by interferon alfa. May increase risk of adverse effects when used with nucleoside reverse transcriptase inhibitors. Potentially Fatal: Risk of fatal hepatic failure, peripheral neuropathy and pancreatitis when used with didanosine. Increased risk of severe neutropenia and anaemia when used with zidovudine.
