Drug interactions
Major drug interactions
Major:
SORAfenib quizartinib
Applies to: sorafenib and quizartinib
Using quizartinib together with SORAfenib can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these medications, whether together or alone. 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.
Therapeutic duplication warnings
Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition.
It can be intentional, when combining drugs with similar actions adds demonstrated therapeutic benefit — or unintentional, such as when a patient sees multiple prescribers or fills prescriptions at more than one pharmacy, which can lead to adverse effects.
Duplication:
Multikinase inhibitors
The recommended maximum number of medicines in the 'multikinase inhibitors' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'multikinase inhibitors' category:
- quizartinib
- sorafenib
Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
SORAfenib Food/Lifestyle
Applies to: sorafenib
You may experience reduced absorption of SORAfenib in the presence of food. Take SORAfenib on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. This will make it easier for your body to absorb the medication.
Moderate:
quizartinib Food/Lifestyle
Applies to: quizartinib
You should avoid the consumption of grapefruit(s) and grapefruit juice while taking quizartinib. Grapefruit may increase the levels of quizartinib in your body. This can affect the rhythm of your heart, which may be serious and potentially life-threatening. You may be more susceptible if you have a heart condition called congenital long QT syndrome, other cardiac diseases, conduction abnormalities, or electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting). The risk and/or severity of other side effects may also increase, including nausea, vomiting, diarrhea, abdominal pain, mouth sores, decreased appetite, 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 fever and infections due to low blood cell counts. You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with quizartinib. 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
9 potential interactions Applies to: 9 conditions, including High Blood Pressure, Underactive Thyroid, Hypokalemia, Heart Disease, and Liver Disease.
Heart Disease
Major:
quizartinib
Quizartinib has a major potential interaction with Heart Disease.
Quizartinib prolongs the QT interval in a dose and concentration dependent manner. Due to the serious risk of QTc prolongation, quizartinib is contraindicated in patients with long QT syndrome, a history of ventricular arrhythmias or torsades de points, severe hypokalemia, or severe hypomagnesemia. Additionally, avoid use in patients who are at significant risk of developing torsades de pointes, including uncontrolled or significant cardiac disease, recent myocardial infarction, heart failure, unstable angina, bradyarrhythmias, tachyarrhythmias, uncontrolled hypertension, high-degree atrioventricular block, severe aortic stenosis, or uncontrolled hypothyroidism. Perform an ECG and correct electrolyte abnormalities before and during treatment as indicated, especially in high-risk patients or during concomitant use with strong CYP450 3A4 inhibitors or drugs known to prolong the QT interval. Do not initiate or escalate therapy in patients with QTcF interval greater than 450 ms; dose adjustments based on QTcF interval may be required.
High Blood Pressure
Major:
quizartinib
Quizartinib has a major potential interaction with High Blood Pressure.
Quizartinib prolongs the QT interval in a dose and concentration dependent manner. Due to the serious risk of QTc prolongation, quizartinib is contraindicated in patients with long QT syndrome, a history of ventricular arrhythmias or torsades de points, severe hypokalemia, or severe hypomagnesemia. Additionally, avoid use in patients who are at significant risk of developing torsades de pointes, including uncontrolled or significant cardiac disease, recent myocardial infarction, heart failure, unstable angina, bradyarrhythmias, tachyarrhythmias, uncontrolled hypertension, high-degree atrioventricular block, severe aortic stenosis, or uncontrolled hypothyroidism. Perform an ECG and correct electrolyte abnormalities before and during treatment as indicated, especially in high-risk patients or during concomitant use with strong CYP450 3A4 inhibitors or drugs known to prolong the QT interval. Do not initiate or escalate therapy in patients with QTcF interval greater than 450 ms; dose adjustments based on QTcF interval may be required.
Hypokalemia
Major:
quizartinib
Quizartinib has a major potential interaction with Hypokalemia.
Quizartinib prolongs the QT interval in a dose and concentration dependent manner. Due to the serious risk of QTc prolongation, quizartinib is contraindicated in patients with long QT syndrome, a history of ventricular arrhythmias or torsades de points, severe hypokalemia, or severe hypomagnesemia.

Interstitial Lung Disease
Moderate:
sorafenib
SORAfenib has a moderate potential interaction with Interstitial Lung Disease.
The use of certain multikinase inhibitors has been associated with pulmonary toxicity. Serious cases of interstitial lung disease (ILD), including fatal cases and interstitial pneumonitis or pulmonary fibrosis have been reported. Caution is recommended when using these agents in patients with a history of interstitial pneumonitis or pulmonary fibrosis or those patients presenting with acute onset of new or progressive unexplained pulmonary symptoms such as dyspnea, cough, and fever pending diagnostic evaluation. If ILD is confirmed, these agents should be permanently discontinued and appropriate measures should be instituted.

Liver Disease
Moderate:
quizartinib
Quizartinib has a moderate potential interaction with Liver Disease.
Midostaurin and quizartinib should be used with caution in patients with severe hepatic or severe renal dysfunction as the pharmacokinetics of these agents have not been studied in these patients. No dosage adjustments are recommended in patients with mild or moderate hepatic or renal dysfunction.
