Curator's Comment: description was created based on several sources, including https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=adf16e64-345f-469a-b987-3fbdd17e0ac2 | http://www.news-medical.net/health/Ribavirin-History.aspx

Ribavirin is a synthetic nucleoside analogue, which was first discovered and developed in 1970 by researchers from the International Chemical & Nuclear Corporation (ICN), today known as Valeant Pharmaceuticals. Ribavirin was initially approved for use in humans to treat pediatric respiratory syncytial virus infections (RSV). In cell cultures the inhibitory activity of ribavirin for RSV is selective. The mechanism of action is unknown. Reversal of the in vitro antiviral activity by guanosine or xanthosine suggests ribavirin may act as an analogue of these cellular metabolites. There were no other significant advancements in the treatment of hepatitis C until 1998, when the combination of ribavirin and interferon-alpha gained approval. Clinically, ribavirin showed a small, additive antiviral effect in combination with interferon, but its main effect was dose-dependent prevention of virological relapse. The mechanism by which the combination of ribavirin and an interferon product exerts its effects against the hepatitis C virus has not been fully established. However, it could be thorough the inhibition of inosine monophosphate dehydrogenase (IMPDH), which is the key step in de novo guanine synthesis, a requirement for viral replication.

Treatment early in the course of severe lower respiratory tract infection may be necessary to achieve efficacy. Only severe RSV lower respiratory tract infection should be treated with VIRAZOLE. The vast majority of infants and children with RSV infection have disease that is mild, self-limited, and does not require hospitalization or antiviral treatment. Many children with mild lower respiratory tract involvement will require shorter hospitalization than would be required for a full course of VIRAZOLE aerosol (3 to 7 days) and should not be treated with the drug. Thus the decision to treat with VIRAZOLE should be based on the severity of the RSV infection. The presence of an underlying condition such as prematurity, immunosuppression or cardiopulmonary disease may increase the severity of clinical manifestations and complications of RSV infection. Use of aerosolized VIRAZOLE in patients requiring mechanical ventilator assistance should be undertaken only by physicians and support staff familiar with this mode of administration and the specific ventilator being used Launch Date 5.04835211E11

Sample Use Guides

In Vivo Use Guide

respiratory syncytial virus infection: 20 mg/mL VIRAZOLE (Ribavirin for inhalation solution) as the starting solution in the drug reservoir of the SPAG-2 unit, with continuous aerosol administration for 12-18 hours per day for 3 to 7 days. Using the recommended drug concentration of 20 mg/mL the average aerosol concentration for a 12 hour delivery period would be 190 micrograms/liter of air. Aerosolized VIRAZOLE should not be administered in a mixture for combined aerosolization or simultaneously with other aerosolized medications. Chronic hepatitis C virus infection: The recommended duration of treatment for patients previously untreated with ribavirin and interferon is 24 to 48 weeks. The daily dose of COPEGUS (ribavirin) tablets is 800 mg to 1200 mg administered orally in two divided doses. The dose should be individualized to the patient depending on baseline disease characteristics (eg, genotype), response to therapy, and tolerability of the regimen.

Route of Administration: Other

In Vitro Use Guide

To determine the optimal concentration and timing of ribavirin treatment for the inhibition of viral transcription, Human A549 pulmonary type II epithelial cells pretreated (2 h) or posttreated (1 h) with increasing concentrations of ribavirin (from10 to 100 microg/ml) were exposed to pRSV (Respiratory syncytial virus). Total cellular RNA was harvested 36 h later, and the abundance of the 1.1-kb RSV N transcript was measured by Northern blotting. Ribavirin treatment potently inhibited RSV transcription, thereby reducing the level of RSV N transcripts to approximately 13% of levels in nontreated cells. In RSV-infected epithelial cells, ribavirin reduces plaque formation, the release of infectious virions, and F glycoprotein expression.
