Drug interactions

Moderate drug interactions

Moderate:

bitolterol osilodrostat

Applies to: bitolterol and osilodrostat

Using bitolterol together with osilodrostat 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

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.

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

14 potential interactions Applies to: 13 conditions, including High Blood Pressure, Heart Failure, Seizures, Arrhythmia, and Hypokalemia.

Adrenal Insufficiency

Moderate:

osilodrostat

Osilodrostat has a moderate potential interaction with Adrenal Insufficiency.

Osilodrostat lowers cortisol levels and can lead to hypocortisolism and sometimes life-threatening adrenal insufficiency. Patients should be evaluated for precipitating causes of hypocortisolism. Serum/plasma cortisol, 24-hour urine free cortisol, and patient's signs/symptoms should be monitored periodically during treatment. Osilodrostat should be decreased or temporarily discontinued if urine free cortisol levels fall below the target range, there is a rapid decrease in cortisol levels, and/or patients report hypocortisolism symptoms. Therapy should be stopped and exogenous glucocorticoid replacement therapy should be administered if serum/plasma cortisol levels are below the target range and patients have symptoms of adrenal insufficiency. Osilodrostat should be restarted at a lower dose when urine free cortisol and serum/plasma cortisol levels are within the target range, and/or patient symptoms have resolved.

Arrhythmia

Moderate:

osilodrostat

Osilodrostat has a moderate potential interaction with Arrhythmia.

The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.

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:

osilodrostat

Osilodrostat has a moderate potential interaction with Electrolyte Abnormalities.

The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.

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.

Heart Failure

Moderate:

osilodrostat

Osilodrostat has a moderate potential interaction with Heart Failure.

The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds. Hypokalemia and hypomagnesemia should be corrected before initiating treatment and monitored regularly during treatment. Electrolyte abnormalities should be corrected if indicated. Care should be exercised when using this agent in patients with risk factors for QT prolongation and more frequent ECG monitoring should be considered.

Hypokalemia

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.

Moderate:

osilodrostat

Osilodrostat has a moderate potential interaction with Hypokalemia.

The use of osilodrostat is associated with a dose-dependent QT interval prolongation, which may cause cardiac arrhythmias. It is recommended to perform an ECG to obtain a baseline QTc interval measurement before starting therapy and to monitor for an effect on the QTc interval thereafter. Temporary discontinuation of osilodrostat should be considered in the case of an increase in QTc interval greater than 480 milliseconds.
