What is Glycerol Phenylbutyrate

Glycerol phenylbutyrate is a nitrogen-binding agent. Chemically, it is a triglyceride in which three molecules of phenylbutyrate are linked to a glycerol backbone. FDA approved on February 1, 2013.

Glycerol Phenylbutyrate mechanism of action

The toxic accumulation of ammonia in the blood and brain arise from urea cycle disorders in which patients are deficient in critical enzymes or transporters that are involved in the synthesis of urea from ammonia. Glycerol phenylbutyrate is a prodrug – the major metabolite, phenylacetate (PAA) is the molecule that binds to nitrogen. PAA conjugates with glutamine (which contains 2 molecules of nitrogen) via acetylation in the liver and kidneys to form phenylacetylglutamine (PAGN), which is excreted by the kidneys. PAGN, like urea, contains 2 moles of nitrogen and provides an alternate vehicle for waste nitrogen excretion.
