Which drug is indicated for the treatment of RSV?

Ribavirin is indicated for the treatment of respiratory syncytial virus (RSV) due to its antiviral properties that specifically target RNA viruses. It works by interfering with the viral replication process, thereby helping to control the infection. Ribavirin is often used in a nebulized form for the treatment of severe RSV infections, particularly in infants and young children who are at high risk for complications.

Other antiviral agents mentioned have different primary indications: Oseltamivir and Zanamivir are primarily used to treat influenza viruses, while Ritonavir is an HIV protease inhibitor that is used in the management of HIV infection. Therefore, Ribavirin stands out as the effective choice for RSV due to its direct application in treating this specific viral infection.
