Which medication is effective against Influenza Type A?

Amantadine is recognized for its effectiveness against Influenza Type A. This medication operates by interfering with the viral replication process and has been shown to reduce the duration and severity of influenza symptoms when administered early in the course of illness.

In contrast, foscarnet, ribavirin, and acyclovir are primarily used against different viral infections and do not have a significant effect on Influenza Type A. Foscarnet is mainly utilized to treat herpes virus infections, ribavirin is commonly used in the treatment of respiratory syncytial virus (RSV) and certain chronic hepatitis C cases, while acyclovir is focused on managing infections caused by the herpes simplex and varicella zoster viruses. Thus, amantadine stands out as the medication specifically targeting Influenza Type A.
