NCIt definition : The sodium salt form of phenylacetate with ammonia detoxifying activity. Upon administration,
sodium phenylacetate binds to glutamine thereby forming phenylacetylglutamine and
is thus excreted by the kidneys. By serving as an alternative to urea for the excretion
of waste nitrogen, sodium phenylacetate is able to lower ammonia levels in the blood
and prevent hyperammonemia.;
