Drug interactions

Moderate drug interactions

Moderate:

zafirlukast bosutinib

Applies to: zafirlukast and bosutinib

Zafirlukast may increase the blood levels of bosutinib. In some cases, this can increase side effects such as nausea, vomiting, abdominal pain, diarrhea, liver problems, fluid retention, and impaired bone marrow function resulting in low numbers of different types of blood cells. You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. 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:

zafirlukast Food/Lifestyle

Applies to: zafirlukast

Zafirlukast should be taken on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. You may experience reduced absorption of zafirlukast in the presence of food. This will make it easier for your body to absorb the medication.

Moderate:

bosutinib Food/Lifestyle

Applies to: bosutinib

Bosutinib should be taken with a meal to help with its absorption. Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with bosutinib unless directed otherwise by your doctor. Grapefruit juice can significantly increase the blood levels of bosutinib. You may be more likely to experience side effects such as nausea, vomiting, abdominal pain, diarrhea, liver damage, 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

11 potential interactions Applies to: 10 conditions, including Heart Failure, Diarrhea, Fluid Retention, Liver Disease, and Dehydration.

Bone Marrow Depression/Low Blood Counts

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Bone Marrow Depression/Low Blood Counts.

Thrombocytopenia, aplastic anemia, agranulocytosis, and neutropenia occur with BCR-ABL tyrosine kinase inhibitors. Therapy with these drugs should be administered cautiously in patients with preexisting bone marrow suppression. A complete blood count should be performed every 1 to 2 weeks for the first month of therapy and then monthly thereafter, or as clinically indicated. To manage myelosuppression, withhold, reduce dose, or discontinue therapy as necessary.

Cardiovascular Conditions and Disorders

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Cardiovascular Conditions and Disorders.

Cardiovascular events (including arterial vascular occlusive events, peripheral arterial occlusive disease, and ischemic cerebrovascular events) have been reported in patients receiving BCR-ABL tyrosine kinase inhibitors. Patients should seek immediate medical attention if acute signs or symptoms of cardiovascular events occur. Cardiovascular status should be evaluated, and cardiovascular risk factors should be monitored and actively managed during treatment.

Dehydration

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Dehydration.

Adequate hydration might be necessary during therapy with bosutinib as diarrhea, nausea, vomiting, and abdominal pain occur with treatment. Monitor and manage patients using standards of care, including antidiarrheals, antiemetics, and fluid replacement. To manage gastrointestinal toxicity, withhold, dose reduce, or discontinue bosutinib as necessary.

Diarrhea

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Diarrhea.

Adequate hydration might be necessary during therapy with bosutinib as diarrhea, nausea, vomiting, and abdominal pain occur with treatment. Monitor and manage patients using standards of care, including antidiarrheals, antiemetics, and fluid replacement. To manage gastrointestinal toxicity, withhold, dose reduce, or discontinue bosutinib as necessary.

Fluid Retention

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Fluid Retention.

Fluid retention occurs with BCR-ABL tyrosine kinase inhibitors therapy and may manifest as pericardial effusion, pleural effusion, pulmonary edema, and/or peripheral edema. Caution should be taken when using these drugs in patients with preexisting fluid retention or congestive heart failure. Monitor and manage patients using standards of care. Interrupt, reduce dose or discontinue therapy as necessary.

Heart Failure

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Heart Failure.

Fluid retention occurs with BCR-ABL tyrosine kinase inhibitors therapy and may manifest as pericardial effusion, pleural effusion, pulmonary edema, and/or peripheral edema. Caution should be taken when using these drugs in patients with preexisting fluid retention or congestive heart failure. Monitor and manage patients using standards of care. Interrupt, reduce dose or discontinue therapy as necessary.

Liver Disease

Major:

zafirlukast

Zafirlukast has a major potential interaction with Liver Disease.

The use of zafirlukast may be associated with elevations of one or more liver enzymes as well as life-threatening hepatic failure. Cases of liver injury without other attributable cause have been reported from postmarketing surveillance of patients treated with the recommended dosage of zafirlukast (40 mg/day). Although most cases have been reversible following drug discontinuation, fulminant hepatitis and progression to hepatic failure, liver transplantation, and death have rarely been reported. In patients with hepatic cirrhosis, serum zafirlukast concentrations may be 50% to 60% higher than in normal patients. Zafirlukast is contraindicated in patients with hepatic impairment including hepatic cirrhosis. Periodic serum transaminase testing is recommended to enable early detection of drug-induced hepatic injury. Patients should be advised to contact their physician immediately if they experience signs or symptoms of liver dysfunction (e.g., right upper quadrant abdominal pain, nausea, fatigue, lethargy, pruritus, jaundice, flu-like symptoms, anorexia, and enlarged liver). Zafirlukast should be discontinued, and liver function tests performed immediately if hepatic injury is suspected. The drug should not be resumed if hepatic injury is confirmed. Patients in whom zafirlukast was withdrawn because of hepatic injury where no other attributable cause is identified should not be re-exposed to zafirlukast.

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Liver Disease.

Bosutinib is primarily metabolized by the CYP 450 3A4. Therapy with bosutinib should be administered cautiously in patients with hepatic impairment and the starting dose should be 200 mg daily in patients with baseline hepatic impairment. The manufacturer recommends performing hepatic enzyme tests monthly for the first three months of bosutinib treatment and as clinically indicated. In patients with transaminase elevations, monitor liver enzymes more frequently. Withhold, reduce dose, or discontinue bosutinib as necessary.

Pleural Effusion

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Pleural Effusion.

Fluid retention occurs with BCR-ABL tyrosine kinase inhibitors therapy and may manifest as pericardial effusion, pleural effusion, pulmonary edema, and/or peripheral edema. Caution should be taken when using these drugs in patients with preexisting fluid retention or congestive heart failure. Monitor and manage patients using standards of care. Interrupt, reduce dose or discontinue therapy as necessary.

Renal Dysfunction

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Renal Dysfunction.

An on-treatment decline in estimated glomerular filtration rate (eGFR) has occurred in patients treated with bosutinib. The manufacturer recommends reducing the bosutinib starting dose in patients with severe (CrCl) less than 30 mL/min) or moderate (CrCl 30 to 50 mL/min) renal impairment at baseline. Consider dose adjustment in patients with baseline and treatment emergent renal impairment. It is recommended to monitor patients for renal function at baseline and during therapy with bosutinib, with particular attention to those patients who have preexisting renal impairment or risk factors for renal dysfunction.

Vomiting

Moderate:

bosutinib

Bosutinib has a moderate potential interaction with Vomiting.

Adequate hydration might be necessary during therapy with bosutinib as diarrhea, nausea, vomiting, and abdominal pain occur with treatment. Monitor and manage patients using standards of care, including antidiarrheals, antiemetics, and fluid replacement. To manage gastrointestinal toxicity, withhold, dose reduce, or discontinue bosutinib as necessary.
