Drug interactions
Moderate drug interactions
Moderate:
alvimopan taurursodiol
Applies to: alvimopan and sodium phenylbutyrate / taurursodiol
Taurursodiol may increase the blood levels and effects of alvimopan. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
sodium phenylbutyrate Food/Lifestyle
Applies to: sodium phenylbutyrate / taurursodiol
Food may affect the absorption of sodium phenylbutyrate. A high-fat, high-calorie meal (approximately 800 to 1000 calories; 500 to 600 calories from fat, 250 calories from carbohydrate, 150 calories from protein) has been shown to reduce the absorption of sodium phenylbutyrate, although it is unknown what impact this may have on the overall effectiveness of the medication. The manufacturer recommends taking sodium phenylbutyrate before a meal or snack. This is especially important if you weigh less than 70 kg (approximately 154 pounds). Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

Disease interactions
15 potential interactions Applies to: 14 conditions, including Heart Failure, Peripheral Neuropathy, Diverticulitis, Inflammatory Bowel Disease, and Peptic Ulcer.
Biliary Obstruction
Moderate:
sodium phenylbutyrate / taurursodiol
The taurursodiol in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Biliary Obstruction.
Sodium phenylbutyrate-taurursodiol contains taurursodiol, a bile acid. In patients with disorders that interfere with bile acid circulation, there may be an increased risk for diarrhea and patients should be monitored appropriately. Other conditions such as pancreatic insufficiency, intestinal malabsorption, or intestinal diseases that may alter the concentration of bile acids, may also lead to decreased absorption of this drug and its components. Consider consulting with a GI specialists with experience managing these GI disorders. Patients with disorders of enterohepatic circulation (e.g., biliary infection, active cholecystitis, etc.), severe pancreatic disorders (e.g., pancreatitis), and intestinal disorders that may alter concentrations of bile acids (e.g., ileal resection, regional ileitis, etc.) were excluded from clinical studies and there is no experience in patients with these conditions. Caution is advised.
Central Nervous System Disorders
Moderate:
sodium phenylbutyrate / taurursodiol
The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Central Nervous System Disorders.
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.
Diverticulitis
Major:
alvimopan
Alvimopan has a major potential interaction with Diverticulitis.
Peripheral opioid receptor antagonists are contraindicated in patients with known or suspected gastrointestinal obstruction, and in patients at increased risk of recurrent obstruction, due to the potential for gastrointestinal perforation. Cases of gastrointestinal perforation have been reported in patients with opioid-induced constipation and advanced illness with conditions that may be associated with localized or diffuse reduction of structure integrity in the wall of the GI tract such as peptic ulcer, diverticular disease, Crohn's disease, infiltrative GI tract malignancies or peritoneal metastases. It is recommended to monitor for the development of severe, persistent, or worsening abdominal pain and to discontinue treatment in patients who develop symptoms. The overall risk- benefit profile should be carefully evaluated before using these agents in patients with these conditions.
Fluid Retention
Major:
sodium phenylbutyrate / taurursodiol
The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a major potential interaction with Fluid Retention.
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.
Gallbladder Disease
Moderate:
sodium phenylbutyrate / taurursodiol
The taurursodiol in sodium phenylbutyrate / taurursodiol has a moderate potential interaction with Gallbladder Disease.
Sodium phenylbutyrate-taurursodiol contains taurursodiol, a bile acid. In patients with disorders that interfere with bile acid circulation, there may be an increased risk for diarrhea and patients should be monitored appropriately. Other conditions such as pancreatic insufficiency, intestinal malabsorption, or intestinal diseases that may alter the concentration of bile acids, may also lead to decreased absorption of this drug and its components. Consider consulting with a GI specialists with experience managing these GI disorders. Patients with disorders of enterohepatic circulation (e.g., biliary infection, active cholecystitis, etc.), severe pancreatic disorders (e.g., pancreatitis), and intestinal disorders that may alter concentrations of bile acids (e.g., ileal resection, regional ileitis, etc.) were excluded from clinical studies and there is no experience in patients with these conditions. Caution is advised.
