Tamiflu May Not Prevent Spread of Flu Saturday April 17, 2010
A new study conducted in Hong Kong showed that oseltamivir (Tamiflu) may not prevent the spread of the flu even though it does shorten the duration of symptoms. This is important because one of the primary reasons that oseltamivir is prescribed in many cases is to reduce the chance that the flu will be spread to other household contacts that may be at high risk for complications.
The study casts doubt over whether or not the medication is useful to prevent the spread of the virus. However, there are a few things about this study that are important to remember:
* The study was relatively small (only 90 participants actually took the medication) * It was conducted over the 2007 and 2008 flu seasons - the results may not be the same with the pandemic H1N1 virus (swine flu) * Results indicate that there may be some protection for others when the oseltamivir is started within the first 24 hours ----------------------
GOOD for Glaxo´s Relenza sales and Biota´s royalities and a open door / big chance for Daiichi´s and Biota´s new drug Laninamivir
