Can you take Dabrafenib with 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.

Dabrafenib has a moderate potential interaction with Bleeding Disorder.

The use of dabrafenib may increase the chance of hemorrhagic events. Care should be exercised when using this drug in patients who have had bleeding problems or who plan to have surgery, dental, or other medical procedures. Dabrafenib should be permanently discontinued for all grade 4 hemorrhagic events and for any grade 3 hemorrhagic events that do not improve. Dabrafenib should be withheld for grade 3 hemorrhagic events; if improved, this drug should resume at the next lower dose level.

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.

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

The use of dabrafenib may result in severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome and drug reaction with eosinophilia and systemic symptoms (DRESS), which can be life-threatening or fatal. Care should be exercised when using this drug in patients at risk of skin toxicities. Patients should be monitored for new or worsening serious skin reactions. Dabrafenib should be permanently discontinued for SCARs. For other skin toxicities, dabrafenib should be withheld for intolerable or severe skin toxicity and should resume at a lower dose upon improvement or recovery within 3 weeks. Dabrafenib should be permanently discontinued if skin toxicity has not improved within 3 weeks.

Dabrafenib has a moderate potential interaction with Diabetes Mellitus.

In clinical trials, patients with a history of diabetes who received dabrafenib required more intensive hypoglycemic therapy. Care should be exercised when using this drug in patients with preexisting diabetes or hyperglycemia. Serum glucose levels should be monitored at the start of therapy and as clinically indicated in these patients. Antihyperglycemic medications should be started or optimized as clinically indicated.

Dabrafenib has a moderate potential interaction with Fever.

Serious febrile reactions and fever of any severity complicated by rigors/chills, hypotension, dehydration, and/or renal failure have been observed with the use of dabrafenib. The incidence and severity of pyrexia are increased when this drug is administered in combination with trametinib compared with dabrafenib as a single agent. It is recommended to withhold therapy for temperature of 38C (100.4F) or higher; in case of recurrence, therapy can be interrupted at first symptom of pyrexia. Patients should be evaluated for signs/symptoms of infection, and it is recommended to monitor serum creatinine and other evidence of renal function during and after severe pyrexia. Antipyretics should be administered as secondary prophylaxis when resuming therapy for patients with prior episode of severe febrile reaction or fever associated with complications. Corticosteroids (e.g., prednisone 10 mg/day) should be administered for at least 5 days for second or subsequent pyrexia if temperature does not return to baseline within 3 days of pyrexia onset, or for pyrexia associated with complications, and there is no evidence of active infection. Upon resolution of pyrexia, dose reduction and/or permanent therapy discontinuation may be required.

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.

Dabrafenib has a moderate potential interaction with G-6-PD Deficiency.

Dabrafenib contains a sulfonamide moiety. Care should be exercised when using this drug in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency as it may increase the risk of hemolytic anemia. Patients with G6PD deficiency should be monitored for signs of hemolytic anemia while taking dabrafenib.

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.

Caution is advised.

Dabrafenib has a moderate potential interaction with Heart Disease.

Cardiomyopathy (defined as a reduction in left ventricular ejection fraction [LVEF] at least 10% from baseline and below the institutional lower limit of normal [LLN]) has been reported with the use of dabrafenib in combination with trametinib. Caution should be exercised when using this drug in patients with heart problems. It is recommended to assess LVEF by echocardiogram or multigated acquisition (MUGA) scan before starting therapy, 1 month after starting, and then every 2 to 3 months while on treatment. Dabrafenib should be withheld for symptomatic cardiomyopathy or asymptomatic left ventricular dysfunction of greater than 20% from baseline that is below institutional LLN. Dabrafenib should resume at the same dose level upon recovery of cardiac function to at least the institutional LLN for LVEF and absolute decrease up to 10% compared to baseline.

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.

Upon resolution of pyrexia, dose reduction and/or permanent therapy discontinuation may be required.

Dabrafenib has a moderate potential interaction with Liver Disease.

Hepatic metabolism and biliary secretion are the primary routes of elimination of dabrafenib and its metabolites; thus, patients with moderate (bilirubin greater than 1.5 to 3 times the upper limit of normal [1.5 to 3 x ULN] and any AST) or severe (bilirubin greater than 3 to 10 x ULN and any AST) liver dysfunction may have increased exposure. An appropriate dosage has not been established for patients with moderate or severe liver dysfunction; care should be exercised when using dabrafenib in these patients. Dose adjustment is not recommended for patients with mild liver dysfunction (bilirubin up to ULN and AST greater than ULN or bilirubin greater than 1 to 1.5 x ULN and any AST).
