Ravicti (glycerol phenylbutyrate) Disease Interactions

There are 4 disease interactions with Ravicti (glycerol phenylbutyrate):


Glycerol Phenylbutyrate (Includes Ravicti) ↔ Fat Malabsorption

Moderate Potential Hazard, Moderate plausibility

Applies to: Malabsorption Syndrome

Pancreatic enzymes hydrolyze glycerol phenylbutyrate in the small intestine. Intestinal disease resulting in fat malabsorption may result in reduced digestion of glycerol phenylbutyrate. It is recommended to monitor the ammonia levels closely in patients with pancreatic insufficiency or intestinal malabsorption.


Glycerol Phenylbutyrate (Includes Ravicti) ↔ Hepatic Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Liver Disease

Patients with hepatic impairment may have higher plasma phenylacetate (PAA) and phenylacetate to phenylacetylglutamine (PAGN) ratio due to a reduced conversion capability of PAA to PAGN in the liver. Patients with moderate to severe hepatic impairment may require lower dosages of glycerol phenylbutyrate than normal to control the patient's ammonia levels. Caution is recommended in patients with hepatic impairment as no studies have been conducted.


Glycerol Phenylbutyrate (Includes Ravicti) ↔ Neuropathy

Moderate Potential Hazard, Moderate plausibility

Applies to: Peripheral Neuropathy

The major metabolite of glycerol phenylbutyrate, PAA, is associated with neurotoxicity. Cases of exacerbation of preexisting neuropathy have been documented in patients using this agent. It is recommended to exercise caution when using glycerol phenylbutyrate in patients with neuropathy.


Glycerol Phenylbutyrate (Includes Ravicti) ↔ Renal Impairment

Moderate Potential Hazard, Moderate plausibility

Applies to: Renal Dysfunction

The efficacy and safety of glycerol phenylbutyrate in patients with renal impairment are unknown. It is recommended to monitor ammonia levels closely when using this agent in patients with impaired renal function.

Drug Interaction Classification

The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No information available.
