Drug interactions

Moderate drug interactions

Moderate:

bitolterol nilotinib

Applies to: bitolterol and nilotinib

Using bitolterol together with nilotinib can increase the risk of an irregular heart rhythm that may be serious and potentially life-threatening, although it is a rare side effect.

You may be more susceptible if you have:

  • a heart condition called congenital long QT syndrome
  • other cardiac diseases
  • conduction abnormalities
  • electrolyte disturbances (for example, magnesium or potassium loss due to severe or prolonged diarrhea or vomiting)

The risk may exist even when bitolterol or similar medications are given by oral inhalation directly into the lungs, and more so if these products are overused. Do not exceed the dose and frequency of use recommended on the product label or prescribed by your doctor.

Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications.

You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with these 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

Major food/lifestyle interactions

Major:

nilotinib Food/Lifestyle

Applies to: nilotinib

Do not consume grapefruit or grapefruit juice during treatment with nilotinib unless directed otherwise by your doctor.

Grapefruit juice can increase the blood levels of nilotinib to dangerous levels, increasing the risk of an irregular heart rhythm that may be serious.

You should seek immediate medical attention if you develop sudden dizziness, lightheadedness, fainting, shortness of breath, or heart palpitations during treatment with nilotinib.

Food may also increase the blood levels of nilotinib. Therefore, you should take nilotinib on an empty stomach, meaning no food should be eaten for at least two hours before or one hour after taking nilotinib.

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.

Moderate food/lifestyle interactions

Moderate:

bitolterol Caffeine

Applies to: bitolterol

Both bitolterol and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects.

Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications.

Contact your doctor if your condition changes or you experience increased side effects.

Disease interactions

15 potential interactions Applies to: 14 conditions, including High Blood Pressure, Seizures, Hypokalemia, Hyperthyroidism, and Lactose Intolerance.

Cardiovascular Conditions and Disorders

Moderate:

nilotinib

Nilotinib 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.

Diabetes Mellitus

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with Diabetes Mellitus.

Adrenergic bronchodilators may cause increases in blood glucose concentrations. These effects are usually transient and slight, but may be significant with dosages higher than those normally recommended. Large doses of IV albuterol (not commercially available in the U.S.) and terbutaline sulfate have been reported to cause exacerbation of preexisting diabetes mellitus and ketoacidosis. Therapy with adrenergic bronchodilators should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate. Systemic adverse effects are minimized, but not abolished, by administration of these agents via oral inhalation.

Electrolyte Abnormalities

Moderate:

nilotinib

Nilotinib has a moderate potential interaction with Electrolyte Abnormalities.

Nilotinib can cause hypophosphatemia, hypokalemia, hyperkalemia, hypocalcemia, and hyponatremia. Electrolyte abnormalities should be corrected prior to initiating nilotinib and during therapy; these electrolytes should be monitored periodically during therapy.

Heart Disease

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with Heart Disease.

Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.

High Blood Pressure

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with High Blood Pressure.

Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.

Hyperthyroidism

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with Hyperthyroidism.

Adrenergic bronchodilators can stimulate cardiovascular beta- 1 and beta- 2 receptors, resulting in adverse effects such as tachycardia, palpitation, peripheral vasodilation, blood pressure changes, and ECG changes (e.g., flattening of the T wave; prolongation of the QT interval; ST segment depression). Direct stimulation of cardiac tissues is mediated by beta- 1 receptors and thus less likely to occur with beta-2-selective agents such as albuterol. However, beta-2-selectivity is not absolute and can be lost with larger doses. High dosages of these agents have been associated with precipitation or aggravation of angina, myocardial ischemia, and cardiac arrhythmias. Therapy with adrenergic bronchodilators should be administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, and/or underlying cardiovascular disorders such as coronary insufficiency, cardiac arrhythmias, or hypertension. The recommended dosages should not be exceeded.

Hypokalemia

Major:

nilotinib

Nilotinib has a major potential interaction with Hypokalemia.

The use of nilotinib is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome. Nilotinib prolongs the QT interval in a concentration-dependent manner; QT prolongation may lead to torsade de pointes, which can result in syncope, seizures, and/or death. Before initiating nilotinib and periodically, electrolyte, calcium, and magnesium blood levels should be tested. Hypokalemia or hypomagnesemia must be corrected before starting treatment and these electrolytes should be monitored periodically. ECGs should be obtained at baseline, 7 days after starting nilotinib, following dose adjustments, and periodically as clinically indicated.

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with Hypokalemia.

Adrenergic bronchodilators may cause decreases in serum potassium concentrations, primarily when given by nebulization or intravenous administration. Although this effect is usually transient and does not require supplementation, clinically significant hypokalemia may occur in some patients, with the potential to induce cardiovascular adverse effects. The relevance of these observations to oral or oral aerosol/powder for inhalation therapy is unknown. Therapy with adrenergic bronchodilators should be administered cautiously in patients with or predisposed to hypokalemia.

Intestinal Anastomoses

Moderate:

nilotinib

Nilotinib has a moderate potential interaction with Intestinal Anastomoses.

Nilotinib exposure is reduced in patients with total gastrectomy. More frequent monitoring of these patients is recommended; a dose increase or alternative therapy should be considered.

Lactose Intolerance

Moderate:

nilotinib

Nilotinib has a moderate potential interaction with Lactose Intolerance.

Nilotinib capsule formulations contain lactose and are not recommended for patients with rare hereditary problems of galactose intolerance, severe lactase deficiency with a severe degree of intolerance to lactose-containing products, or glucose-galactose malabsorption.

Liver Disease

Moderate:

nilotinib

Nilotinib has a moderate potential interaction with Liver Disease.

Nilotinib exposure is increased in patients with hepatic impairment. If possible, alternative therapies should be considered; if nilotinib use is necessary, the dosage should be reduced and the QT interval should be monitored closely. Nilotinib may cause hepatotoxicity as measured by elevations in bilirubin, AST, ALT, and alkaline phosphatase; liver function tests should be monitored monthly or as clinically indicated and after dosage adjustments.

Long QT Syndrome

Major:

nilotinib

Nilotinib has a major potential interaction with Long QT Syndrome.

The use of nilotinib is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome. Nilotinib prolongs the QT interval in a concentration-dependent manner; QT prolongation may lead to torsade de pointes, which can result in syncope, seizures, and/or death. Before initiating nilotinib and periodically, electrolyte, calcium, and magnesium blood levels should be tested. Hypokalemia or hypomagnesemia must be corrected before starting treatment and these electrolytes should be monitored periodically. ECGs should be obtained at baseline, 7 days after starting nilotinib, following dose adjustments, and periodically as clinically indicated.

Magnesium Imbalance

Major:

nilotinib

Nilotinib has a major potential interaction with Magnesium Imbalance.

The use of nilotinib is contraindicated in patients with hypokalemia, hypomagnesemia, or long QT syndrome. Nilotinib prolongs the QT interval in a concentration-dependent manner; QT prolongation may lead to torsade de pointes, which can result in syncope, seizures, and/or death. Before initiating nilotinib and periodically, electrolyte, calcium, and magnesium blood levels should be tested. Hypokalemia or hypomagnesemia must be corrected before starting treatment and these electrolytes should be monitored periodically. ECGs should be obtained at baseline, 7 days after starting nilotinib, following dose adjustments, and periodically as clinically indicated.

Pancreatitis

Moderate:

nilotinib

Nilotinib has a moderate potential interaction with Pancreatitis.

Nilotinib can increase serum lipase. Patients with a history of pancreatitis may be at greater risk of elevated serum lipase. Serum lipase should be monitored monthly or as clinically indicated. If lipase elevations occur with abdominal symptoms, treatment should be interrupted and appropriate diagnostic evaluation should be considered to exclude pancreatitis.

Seizures

Moderate:

bitolterol

Bitolterol has a moderate potential interaction with Seizures.
