Drug interactions

Moderate drug interactions

Moderate:

potassium bitartrate cabozantinib

Applies to: Ceo-Two (potassium bitartrate / sodium bicarbonate) and cabozantinib
Monitor

Bowel cleansing as well as overuse of certain laxatives may cause electrolyte loss and increase the risk of torsade de pointes ventricular arrhythmia in patients treated with drugs that prolong the QT interval. Electrolyte disturbances including hypokalemia and hypomagnesemia have been reported with laxative abuse and are known risk factors for torsade de pointes associated with QT interval prolongation.

Management

Patients treated with drugs that prolong the QT interval should exercise caution when self-medicating with laxatives. The recommended dosage and duration of use should not be exceeded. Patients treated with lactulose for more than six months should be monitored periodically for electrolyte imbalance. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Food/lifestyle interactions

Moderate food/lifestyle interactions

Moderate:

cabozantinib Food/Lifestyle

Applies to: cabozantinib
Adjust dosing interval

Food may alter the oral bioavailability of cabozantinib. When healthy subjects were given a single 140 mg oral dose with a high-fat meal, cabozantinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 41% and 57%, respectively, relative to administration under fasting conditions. In clinical studies, patients were administered cabozantinib without food.

Generally avoid

Coadministration with grapefruit juice is likely to increase the plasma concentrations of cabozantinib, which is primarily metabolized by CYP450 3A4. However, the interaction has not been studied. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.

Management

Cabozantinib should be administered at least one hour before or two hours after a meal. The consumption of grapefruit, grapefruit juice, and supplements that contain grapefruit extract should be avoided.

Disease interactions

18 potential interactions Applies to: 17 conditions, including High Blood Pressure, Heart Failure, Heart Attack, Diverticulitis, and Inflammatory Bowel Disease.

Alkalosis

Moderate:

Ceo-Two

The sodium bicarbonate in Ceo-Two has a moderate potential interaction with Alkalosis.

Alkalinizing agents act as proton acceptors and/or dissociate to provide bicarbonate ions. Elimination of bicarbonate is decreased in patients with renal impairment and can result in metabolic alkalosis. Symptoms of metabolic alkalosis include hyperirritability or tetany, arrhythmia, and/or seizures (altered pH = altered calcium), or lactic acidosis due to impaired oxygen release. Therapy with alkalinizing agents should be administered with extreme caution in patients with compromised renal function. Clinical monitoring of renal function, acid/base balance and electrolytes is recommended.

Bleeding Disorder

Major:

cabozantinib

Cabozantinib has a major potential interaction with Bleeding Disorder.

Fatal hemorrhagic events have been reported with the use of cabozantinib. Therapy with cabozantinib is not recommended in patients that have or are at risk for severe hemorrhage.

Diverticulitis

Moderate:

cabozantinib

Cabozantinib has a moderate potential interaction with Diverticulitis.

Therapy with cabozantinib should be used with caution in patients who may be at increased risk for gastrointestinal perforation, such as those with a history of diverticulitis. Patients presenting with new onset of abdominal symptoms should be evaluated promptly for early identification of gastrointestinal perforation. It is recommended to monitor for symptoms of gastrointestinal perforation or fistula periodically throughout the treatment. Discontinue cabozantinib in patients who experience a fistula which cannot be appropriately managed or a GI perforation.

Fluid Retention

Major:

Ceo-Two

The sodium bicarbonate in Ceo-Two has a major potential interaction with Fluid Retention.

Alkalinizing agents containing sodium can induce sodium and water retention and result in hypernatremia, hypokalemia, hyperosmolality, edema and aggravation of congestive heart failure. Therapy with sodium- containing alkalinizing agents should not be used in patients with hypernatremia or fluid retention. Clinical monitoring of acid/base balance and electrolytes prior to, during, a following completion of therapy with alkalinizing agents is recommended.

Gastrointestinal Obstruction

Major:

Ceo-Two

The potassium bitartrate in Ceo-Two has a major potential interaction with Gastrointestinal Obstruction.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

Gastrointestinal Perforation

Moderate:

cabozantinib

Cabozantinib has a moderate potential interaction with Gastrointestinal Perforation.

Therapy with cabozantinib should be used with caution in patients who may be at increased risk for gastrointestinal perforation, such as those with a history of diverticulitis. Patients presenting with new onset of abdominal symptoms should be evaluated promptly for early identification of gastrointestinal perforation. It is recommended to monitor for symptoms of gastrointestinal perforation or fistula periodically throughout the treatment. Discontinue cabozantinib in patients who experience a fistula which cannot be appropriately managed or a GI perforation.

Heart Attack

Moderate:

cabozantinib

Cabozantinib has a moderate potential interaction with Heart Attack.

Arterial and venous thromboembolic events have been reported with the use of cabozantinib. Use with caution in patients who are at risk, or have a history of these events. It is recommended to monitor closely for signs and symptoms of thromboembolism. Discontinue cabozantinib in patients who develop an acute myocardial infarction or any other arterial thromboembolic complication.

Heart Failure

Major:

Ceo-Two

The sodium bicarbonate in Ceo-Two has a major potential interaction with Heart Failure.

Alkalinizing agents containing sodium can induce sodium and water retention and result in hypernatremia, hypokalemia, hyperosmolality, edema and aggravation of congestive heart failure. Therapy with sodium- containing alkalinizing agents should not be used in patients with hypernatremia or fluid retention. Clinical monitoring of acid/base balance and electrolytes prior to, during, a following completion of therapy with alkalinizing agents is recommended.

High Blood Pressure

Moderate:

cabozantinib

Cabozantinib has a moderate potential interaction with High Blood Pressure.

The use of cabozantinib causes hypertension. Blood pressure should be well-controlled prior to initiating cabozantinib and monitored and treated as needed with standard anti-hypertensive therapy. It is recommended to reduce the dose in case of persistent hypertension despite use of anti-hypertensive medications and to discontinue therapy if hypertension is severe and persistent despite these measures. Discontinue cabozantinib therapy for severe hypertension that cannot be controlled with anti-hypertensive therapy and if there is evidence of hypertensive crisis or severe hypertension despite optimal medical management. Close monitoring is recommended.

Hypernatremia

Major:

Ceo-Two

The sodium bicarbonate in Ceo-Two has a major potential interaction with Hypernatremia.

Alkalinizing agents containing sodium can induce sodium and water retention and result in hypernatremia, hypokalemia, hyperosmolality, edema and aggravation of congestive heart failure. Therapy with sodium- containing alkalinizing agents should not be used in patients with hypernatremia or fluid retention. Clinical monitoring of acid/base balance and electrolytes prior to, during, a following completion of therapy with alkalinizing agents is recommended.

Inflammatory Bowel Disease

Major:

Ceo-Two

The potassium bitartrate in Ceo-Two has a major potential interaction with Inflammatory Bowel Disease.

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.
