Drug interactions

Moderate drug interactions

Moderate:

mitapivat taurursodiol

Applies to: mitapivat and sodium phenylbutyrate / taurursodiol

Taurursodiol may increase the blood levels and effects of mitapivat. 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

Major food/lifestyle interactions

Major:

mitapivat Food/Lifestyle

Applies to: mitapivat

Grapefruit juice can increase the blood levels of mitapivat. This may increase side effects such as joint pain, increased uric acid blood levels, back pain, and in men, decreased reproductive hormones. You should avoid consuming grapefruit and grapefruit juice during treatment with mitapivat. However, if you have been regularly consuming grapefruit or grapefruit juice with the medication, then it is advisable for you to talk with your doctor before changing the amounts of these products in your diet, as this may alter the effects of your medication. Talk to your doctor if you have any questions or concerns. 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.

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

13 potential interactions Applies to: 10 conditions, including Heart Failure, Peripheral Neuropathy, Gallbladder Disease, Fluid Retention, and Liver Disease.

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.

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.

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.
