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.

You should be warned not to exceed recommended dosages and to avoid activities requiring mental alertness. If your doctor prescribes these medications together, you may need a dose adjustment to safely take this combination. 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.

Disease interactions

20 potential interactions Applies to: 18 conditions, including Heart Failure, Peripheral Neuropathy, Myasthenia Gravis, Dementia, and Inflammatory Bowel Disease.

Autonomic Neuropathy

Major:

oxybutynin

oxyBUTYnin has a major potential interaction with Autonomic Neuropathy.

Agents with anticholinergic activity can exacerbate many of the manifestations of autonomic neuropathy, including tachycardia, anhidrosis, bladder atony, obstipation, dry mouth and eyes, cycloplegia and blurring of vision, and sexual impotence in males. Therapy with antimuscarinic agents and higher dosages of antispasmodic agents (e.g., dicyclomine or oxybutynin) should be administered cautiously in patients with autonomic neuropathy.

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:

oxybutynin

oxyBUTYnin has a moderate potential interaction with Central Nervous System Disorders.

Oxybutynin is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Oxybutynin should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.

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.

Dementia

Moderate:

oxybutynin

oxyBUTYnin has a moderate potential interaction with Dementia.

Oxybutynin is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Oxybutynin should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.

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.

Gastrointestinal Obstruction

Major:

oxybutynin

oxyBUTYnin has a major potential interaction with Gastrointestinal Obstruction.

The use of oxybutynin is contraindicated in patients with GI obstruction, ileus, atony, megacolon, toxic megacolon associated with ulcerative colitis, severe colitis, and obstructive uropathy. Oxybutynin exerts direct antispasmodic effects on smooth muscles and possesses anticholinergic activity (1/5 that of atropine).

Glaucoma/Intraocular Hypertension

Major:

oxybutynin

oxyBUTYnin has a major potential interaction with Glaucoma/Intraocular Hypertension.

The use of oxybutynin is contraindicated in patients with uncontrolled angle-closure (narrow angle) or narrow anterior chamber glaucoma. Oxybutynin exerts anticholinergic activity (1/5 that of atropine) and can result in increased intraocular pressure and loss of accommodation.

Heart Failure

Major:

sodium phenylbutyrate / taurursodiol

The sodium phenylbutyrate in sodium phenylbutyrate / taurursodiol has a major potential interaction with Heart Failure.

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.

Infectious Gastroenteritis

Major:

oxybutynin

oxyBUTYnin has a major potential interaction with Infectious Gastroenteritis.

The use of drugs with antiperistaltic activity (primarily antidiarrheal and antimuscarinic agents, but also antispasmodic agents such as dicyclomine or oxybutynin at high dosages) is contraindicated in patients with diarrhea due to pseudomembranous enterocolitis or enterotoxin-producing bacteria. These drugs may prolong and/or worsen diarrhea associated with organisms that invade the intestinal mucosa, such as toxigenic E. coli, Salmonella and Shigella, and pseudomembranous colitis due to broad-spectrum antibiotics. Other symptoms and complications such as fever, shedding of organisms and extraintestinal illness may also be increased or prolonged. In general, because antiperistaltic agents decrease gastrointestinal motility, they may delay the excretion of infective gastroenteric organisms or toxins and should be used cautiously in patients with any infectious diarrhea, particularly if accompanied by high fever or pus or blood in the stool. Some cough and cold and other combination products may occasionally include antimuscarinic agents for their drying effects and may, therefore, require careful selection when necessary.

Inflammatory Bowel Disease

Major:

oxybutynin

oxyBUTYnin has a major potential interaction with Inflammatory Bowel Disease.

The use of oxybutynin is contraindicated in patients with GI obstruction, ileus, atony, megacolon, toxic megacolon associated with ulcerative colitis, severe colitis, and obstructive uropathy.
