Mechanism of action of Oseltamivir (Tamiflu) as an antiviral agent is:
Inhibition of M2 receptor
Neuraminidase inhibition
Inhibition of RNA dependent DNA polymerase
Apoptosis of infected cells
Answer- B. Neuraminidase inhibitionThe neuraminidase inhibitors oseltamivir and zanamivir, analogs of sialic ocid, interfere with release of progenyinfluenza vitus from infected host cells, thas halting the spread of infection within the respiratory tract. These agentscompetitively and reversibly interact with the active enzyme site to inhibit viral neuraminidase activity at low nanomolar concentrations.
