Drug interactions

Moderate drug interactions

Moderate:

ribociclib taurursodiol

Applies to: ribociclib and sodium phenylbutyrate / taurursodiol

Using taurursodiol together with ribociclib may lead to a buildup of bile salts in the liver and cause liver problems. 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. 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.

Moderate:

ribociclib Food/Lifestyle

Applies to: ribociclib

Patients should not consume pomegranates, pomegranate juice, grapefruit, or grapefruit juice during treatment with ribociclib unless directed otherwise by your doctor. Pomegranate juice or grapefruit juice can increase the blood levels of ribociclib. You may be more likely to experience side effects such as nausea; vomiting; diarrhea; loss of appetite; abdominal pain; mouth sores; hair loss; weakness; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. 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: 17 conditions, including High Blood Pressure, Underactive Thyroid, Heart Failure, Peripheral Neuropathy, and Heart 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.

Dermatitis, Drug-Induced

Moderate:

ribociclib

Ribociclib has a moderate potential interaction with Dermatitis, Drug-Induced.

Patients receiving ribociclib have developed severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug-induced hypersensitivity syndrome/drug reaction with eosinophilia and systemic symptoms. This drug must not be reintroduced in patients who have experienced SCARs or other life-threatening cutaneous reactions during ribociclib treatment.

Electrolyte Abnormalities

Moderate:

ribociclib

Ribociclib has a moderate potential interaction with Electrolyte Abnormalities.

Ribociclib has been shown to prolong the QT interval in a concentration-dependent manner.

ECG should be performed in all patients prior to initiation of treatment; ribociclib should be started only in patients with QTcF (QT corrected for heart rate using Fridericia's formula) values less than 450 milliseconds. ECG should be repeated at Day 14 of the first cycle, and as clinically indicated. Serum electrolytes (including potassium, calcium, phosphorous, and magnesium) should be monitored before the initiation of treatment, at the beginning of the first 6 cycles, and as clinically indicated; any electrolyte abnormality should be corrected before starting this drug. Ribociclib may require dose interruption, dose reduction, or discontinuation according to observed QT prolongation during therapy.

Moderate:

ribociclib

Ribociclib has a moderate potential interaction with Liver Disease.

Ribociclib undergoes extensive hepatic metabolism mainly via CYP450 3A4 in humans. Increases in transaminases and drug-induced liver injury have occurred in clinical studies. The starting dose of ribociclib should be reduced to 400 mg in patients with advanced or metastatic breast cancer who have moderate or severe liver dysfunction (Child-Pugh B or C).
