All the above drugs are antivirals and work in the same way by inhibiting viral neuraminidase which reduces viral replication. They are most effective for the treatment of influenza if started within a few hours of the onset of symptoms. They are also used for prophylaxis (prevention) post exposure to influenza. The main difference is the way they are given, peramivir saved for more serious cases.

Oseltamivir is given in the form of a capsule or suspension.
Zanamivir is given as a dry power for inhalation.
