the disposition of sodium benzoate was monitored in four hyperammonemic newborn infants , using a simple and newly developed assay for benzoate and hippurate , to assess ( 1 ) the metabolic capability of patients of this age to utilize this pathway for nitrogen removal , ( 2 ) the potential risks of benzoate toxicity at clinically achieved serum benzoate concentrations , and ( 3 ) the value of routine monitoring of serum benzoate concentrations in this patient population .
