Because the enzyme that eliminates ammonia in the brain is present only in astrocytes, neurons are virtually defenseless against increased ammonia concentrations and therefore are likely to suffer ammonia–related damage..

What are the symptoms of high ammonia levels?

What medication is given to reduce ammonia levels?

Lactulose is also used to reduce the amount of ammonia in the blood of patients with liver disease. It works by drawing ammonia from the blood into the colon where it is removed from the body.

It can also be used to form a chemical compound called urea. Your bloodstream moves the urea to your kidneys, where it is eliminated in your urine.

What is a critical ammonia level?
