Randomized, double-blind, controlled study of glycerol phenylbutyrate in hepatic encephalopathy

Abstract

GPB reduced HE events as well as ammonia in patients with cirrhosis and HE and its safety profile was similar to placebo. The findings implicate ammonia in the pathogenesis of HE and suggest that GPB has therapeutic potential in this population. (Clinicaltrials.gov, NCT00999167).
