Glycerol phenylbutyrate binds with other substances in the liver and kidneys to help eliminate nitrogen from the body.

Ammonia is very toxic when it circulates in blood and tissues and can cause permanent brain damage, coma, or death.

Glycerol phenylbutyrate helps prevent a build-up of ammonia in the blood in people with urea cycle disorder. glycerol phenylbutyrate is used in adults and children who are at least 2 months old. Glycerol phenylbutyrate will not treat hyperammonemia.

Glycerol phenylbutyrate is usually given together with a low-protein diet and sometimes dietary supplements.
