    What is Oseltamivir phosphate ? 

    Oseltamivir is an drug,a neuramini-dase inhibi-tor used in the treatment and prophylaxis of both influenza A and influenza B.

    Oseltamivir is a prodrug (usually administered as phosphate),Oseltamivir phosphate is hydrolysed hepatically to the active metabolite, the free carboxylate of oseltamivir (GS4071).
    Like zanamivir,oseltamivir acts as a transition-state analogue inhibitor of influenza neuraminidase.

    Oseltamivir phosphate is an ethyl ester prodrug requiring ester hydrolysis for conversion to the active form, oseltamivir
    carboxylate. The proposed mechanism of action of oseltamivir is inhibition of influenza virus neuraminidase with the possibility of alteration of virus particle aggregation and release.
