Pheburane Disease Interactions

There are 3 disease interactions with Pheburane (sodium phenylbutyrate).

Major

Sodium phenylbutyrate (applies to Pheburane) fluid retention

Major Potential Hazard, High plausibility. Applicable conditions: Congestive Heart Failure, Renal Dysfunction

The use of sodium phenylbutyrate may cause fluid retention in patients with congestive heart failure, renal dysfunction, or sodium retention with edema. Sodium phenylbutyrate is primarily excreted by the kidney and these patients may exhibit reduced excretion. Therapy with sodium phenylbutyrate should be administered cautiously in these patients. Monitoring plasma levels of ammonia, arginine, branched-chain amino acids and serum proteins to maintain within normal limits and glutamine to less than 1000 mcmol/L is recommended.

Moderate

Sodium phenylbutyrate (applies to Pheburane) liver/kidney disease

Moderate Potential Hazard, High plausibility. Applicable conditions: Liver Disease, Renal Dysfunction

Sodium phenylbutyrate is primarily metabolized in the liver and kidney. Therapy with sodium phenylbutyrate should be administered cautiously in patients with liver disease. Monitoring plasma levels of ammonia, arginine, branched-chain amino acids and serum proteins to maintain within normal limits and glutamine to less than 1000 mcmol/L is recommended.

Moderate

Sodium phenylbutyrate (applies to Pheburane) neurotoxicity

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: CNS Disorder, Myoneural Disorder, Peripheral Neuropathy

Sodium phenylbutyrate is a pro-drug and is rapidly metabolized to the active, phenylacetate. Neurotoxicity, including exacerbation of a preexisting neuropathy, has been reported with the use of intravenous phenylacetate. The acute onset and reversibility when the phenylacetate infusion was discontinued suggested a drug effect. Care should be exercised when prescribing sodium phenylbutyrate to patients at risk for neurotoxicity.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
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 interaction information available.
