How does TAMIFLU works...

hii..friends as all of are now well aware SWINE FLU..there are several drugs coming to the market..one of which is TAMIFLU..which has being widely used in majority of the cases..so it'll be interesting to know about its functioning..
Its an antiviral drug marketed by Swiss pharmaceutical company ROCHE it belongs to the group of drugs called neuraminidase inhibitors and can shorten and lessen the severity of both Type A and B strains of flu as well as bird flu. It targets the neuraminidase protein which is present in the flu virus cells.the protein helps the virus to break to the cell walls
so it can move on to the other cells and replicate itself. Tamiflu inhibits the neuraminidase protein ,so that virus cannot leave the cell and cannot infect the other cells. Eventually the virus dies.
