SummaryPlasma concentration-time data for benzoic and hippuric acids and urinary excretion-time data for hippuric acid were analyzed simultaneously after oral doses of 40, 80 or 160 mg/kg sodium benzoate administered at least one week apart to 6 healthy subjects.The mean AUCs of benzoic acid after the doses of 80 and 160 mg/kg of sodium benzoate were 3.7- and 12.0-times greater, respectively, than after 40 mg/kg. However, the mean AUC of hippuric acid was roughly proportional to the benzoate… 

Effect of single oral dose of sodium benzoate on ureagenesis in healthy men and two patients with late onset citrullinaemia

Examination of aspects of ureagenesis after the single oral dosing of sodium benzoate in six healthy subjects who participated in the study previously reported and in two patients with citrullinaemia found no apparent inhibitory effects on the UNA.

The Effect of Oral Intake of Sodium Benzoate on the Activity of Liver Marker Enzymes and Electrolyte Level of the Wistar Albino Rats

In vivo effect of oral administration of sodium benzoate on serum liver marker enzyme activity and electrolyte levels of wistar albino rats were investigated to suggest possible changes in blood chemistry due to the preservative.

Influence of coffee intake on urinary hippuric acid concentration.

The findings suggest that toluene exposure in coffee-consuming workers may be overestimated, and components of coffee, such as chlorogenic, caffeic, and quinic acids, are metabolized to HA.

Adverse Effects of Some Food Additives in Adult Male Albino Rats

It is concluded that tartrazine, monosodium glutamate, sunset yellow, and sodium benzoate adversely affect and alter different biochemical parameters, especially those related to vital organs e.g. liver and kidney and that sunset yellow has the least adverse effects in comparison with the other food additives.

Pharmacokinetic parameters in patients with rheumatoid arthritis, osteoarthritis, chronic renal failure or liver disease are essentially the same, and no significant differences exist between the pharmacokinetics of the salicylates in the elderly or in children when compared with young adults.
