Which antiviral is known for its use in the treatment of influenza?

• A. Valganciclovir
• B. Zanamivir
• C. Ribavirin
• D. Lamivudine

Answer: (B)

Zanamivir is an antiviral medication specifically indicated for the treatment of influenza. It belongs to a class of drugs known as neuraminidase inhibitors, which obstruct the action of the neuraminidase enzyme on the surface of the influenza virus. By inhibiting this enzyme, zanamivir effectively prevents the virus from spreading within the respiratory tract and reduces the severity and duration of influenza symptoms. This makes zanamivir a targeted treatment option during influenza outbreaks, distinguishing it from other antiviral agents that are not primarily focused on influenza. For example, valganciclovir is mainly used to treat cytomegalovirus (CMV) infections, ribavirin is utilized for chronic hepatitis C and some viral hemorrhagic fevers, and lamivudine is indicated for the treatment of HIV and hepatitis B virus infections. Therefore, zanamivir is the appropriate choice when considering antiviral agents specifically used for influenza treatment.
