Usage

Funtion of Oseltamivide phosphate
Oseltamivide phosphate is rapidly metabolized to oseltamivir carboxylate by absorption through the gastrointestinal tract and at least 75% of the oral dose is involved in systemic circulation in the form of oseltamivir carboxylate.

The active ingredient Is a potent and unique neuraminidase inhibitor that acts on all aspects of influenza virus infection andprevents the replication of all clinically relevant strains of influenza A or B viruses. In vitro in very low nanomolar concentrations that have inhibitory effect.
The active metabolite was observed to inhibit the growth of influenza virus in vitro and it was also observed in vivo to inhibit the replication and pathogenicity of influenza virus.

Oseltamivide phosphate reduces the spread of influenza A or B viruses by inhibiting the release of the virus from the infected cells.
