Neuraminidase inhibitors are a class of antivirals that have activity against both influenza A and B viruses. Influenza neuraminidase cleaves terminal sialic acid residues and damages the receptors recognized by viral hemagglutinin, thereby facilitating release of virus from infected cells. In the presence of a neuraminidase inhibitor, release of virus from infected cells is impaired and the progeny viruses that are freed clump together, as sialic acid has not been cleaved.
