Assignee: The Johns Hopkins University (Baltimore, MD)
Application Number:06/135,685
Patent Claims: 1. A process for controlling waste nitrogen accumulation diseases in humans, caused by an impairment in the normal synthesis of urea from ordinary waste nitrogen in the body or in the normal excretion thereof, said process comprising administering an effective amount of at least one compound selected from the group consisting of benzoic acid, phenylacetic acid and the non-toxic, pharmaceutically-acceptable salts of said acids to a human suffering from such waste nitrogen accumulation disease, the amount of said compound used being sufficient to react with the waste nitrogen to form an amino acid acylation product for urinary discharge of said product.

2. The process of claim 1 wherein a mixture of benzoic acid and phenylacetic acid, or salts thereof, is administered.

3. The process of claim 1 wherein the administration is continued until the accumulated waste nitrogen is discharged as urinary nitrogen.

4. The process of claim 1 wherein the human is one with a urea-cycle enzymopathy.

5. The process of claim 1 wherein the human is one suffering from uremia.

6. The process of claim 1 wherein the human is one suffering from a hepatic disorder.

7. The process of claim 1 wherein the human is one suffering from Reye's syndrome.

8. The process of claim 1 wherein the administration of the benzoic acid or phenylacetic acid, or salts thereof, synthesizes hippuric acid and phenylacetylglutamine, respectively, and the synthesized product is discharged as urinary nitrogen.

9. The process of claim 1 wherein the salt is sodium salt.
