(33) Oseltamivir and Zanamavir
remain effective against most strains, but resistance is rising.
Among the 2009 influenza A (H1N1) viruses, the 87 tested for resistance to oseltamivir were 100% sensitive, and the 33 tested for resistance to zanamavir
were 100% sensitive.
We are definitely going to produce, and are producing already, zanamavir
as an alternative.
Two antiviral medications, oseltamivir and Zanamavir
, would probably work to treat flu caused by the H5N1 virus, though studies still need to be done to prove that they would be effective.
Susceptibility testing continues for zanamavir
Two other antiviral medications, oseltamivir and zanamavir
, would probably work to treat influenza caused by H5N1 virus, but additional studies are needed to demonstrate their current and ongoing effectiveness.
Testing for susceptibility of the H5N1 isolates to the neuraminidase inhibitor oseltamivir has demonstrated the sensitivity of these viruses to the drug; testing to determine susceptibility to the neuraminidase inhibitor zanamavir
is under way.
