Antivirals are medications that keep viruses from reproducing inside the body. To date, relatively few effective antiviral drugs have been developed. It is difficult to create effective antiviral medications because viruses are tiny (smaller than bacteria and fungi) and use a cellâs metabolic pathways to replicate.
The two main classes of antiviral drugs used against influenza are neuraminidase inhibitors, such as zanamivir and oseltamivir, or inhibitors of the viral M2 protein, such as amantadine and rimantadine. These drugs can reduce the severity of symptoms if taken soon after infection and can also be taken to decrease the risk of infection.
