Drug interactions

Moderate drug interactions

Moderate:

itraconazole propafenone

Applies to: Sporanox (itraconazole) and propafenone

Itraconazole may significantly increase the blood levels of propafenone in some patients. This can increase serious side effects such as: new or worsening irregular heart rhythm or heart failure; chest pain; difficulty breathing; fluid retention and swelling; and slow heart rate and pulse. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both 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:

itraconazole Food/Lifestyle

Applies to: Sporanox (itraconazole)

Food increases the absorption of itraconazole capsules but decreases the absorption of itraconazole oral solution. Capsules should be taken immediately after a full meal and the solution be taken on an empty stomach to ensure best results.

Moderate:

propafenone Food/Lifestyle

Applies to: propafenone

Consumption of grapefruit, grapefruit juice, and supplements that contain grapefruit should be avoided during treatment with propafenone as they may increase the blood levels of propafenone in some patients. This can cause serious side effects such as new or worsening irregular heart rhythm or heart failure; chest pain; difficulty breathing; fluid retention and swelling; and slow heart rate and pulse. Talk to your doctor if you have any questions or concerns. 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

24 potential interactions Applies to: 19 conditions, including Heart Failure, Asthma, COPD, Arrhythmia, and Hypokalemia.

Achlorhydria

Moderate:

Sporanox

The itraconazole in Sporanox has a moderate potential interaction with Achlorhydria.

Itraconazole 100-mg capsules should be administered after a full meal. Under fasted conditions, absorption of itraconazole from the 100-mg capsule formulation was diminished with decreased gastric acidity. Studies conducted under fasted conditions showed that taking the 100-mg capsule formulation with 8 ounces of a non-diet cola beverage enhanced absorption of itraconazole in AIDS patients with relative or absolute achlorhydria; this increase relative to the effects of a full meal is unknown.

Arrhythmia

Moderate:

Sporanox

The itraconazole in Sporanox has a moderate potential interaction with Arrhythmia.

Some azole antifungals have been associated with prolongation of the QT interval on the ECG. Rare cases of QT prolongation and torsade de pointes have been reported during postmarketing experience; such reports usually involved seriously ill patients with multiple confounding risk factors, such as structural heart disease, electrolyte abnormalities, and concomitant medications. These drugs should be administered with caution to patients with potentially proarrhythmic conditions, such as congenital/acquired QT prolongation, cardiomyopathy (especially when heart failure is present), sinus bradycardia, and existing symptomatic arrhythmias. Concomitant use with other medications that have potential to increase the risk of cardiotoxicity should be avoided.

Asthma

Major:

propafenone

Propafenone has a major potential interaction with Asthma.

The use of propafenone is contraindicated in patients with bronchospastic disorders or severe obstructive pulmonary disease. Propafenone has beta-adrenergic blocking properties.

COPD

Major:

propafenone

Propafenone has a major potential interaction with COPD.

The use of propafenone is contraindicated in patients with bronchospastic disorders or severe obstructive pulmonary disease. Propafenone has beta-adrenergic blocking properties.

Major:

Sporanox

The itraconazole in Sporanox has a major potential interaction with COPD.

Itraconazole may possess a dose-related negative inotropic effect. Transient, asymptomatic decreases in left ventricular ejection fraction were observed with IV administration in healthy volunteers; these resolved before the next infusion. Additionally, cases of congestive heart failure (CHF), peripheral edema, and pulmonary edema have been reported during postmarketing experience in patients treated for onychomycosis and/or systemic fungal infections. Itraconazole should not be used to treat onychomycosis in patients with evidence of ventricular dysfunction such as CHF or history of CHF; itraconazole should not be used for other indications in such patients unless the benefit clearly outweighs the risk. The risks and benefits of itraconazole therapy should be reviewed carefully in patients with risk factors for CHF (including cardiac disease [e.g., ischemic and valvular disease], significant pulmonary disease [e.g., chronic obstructive pulmonary disease], renal failure and other edematous disorders). Patients with risk factors for CHF should be advised of the signs/symptoms of CHF, treated with caution, and monitored for signs/symptoms of CHF during therapy.

Cystic Fibrosis

Moderate:

Sporanox

The itraconazole in Sporanox has a moderate potential interaction with Cystic Fibrosis.

In a study using itraconazole oral solution in cystic fibrosis patients, therapeutic drug levels varied and were not reached in some patients. Alternative therapy should be considered for patients who do not respond to itraconazole oral solution or itraconazole 100-mg capsules.

Fluid Retention

Major:

Sporanox

The itraconazole in Sporanox has a major potential interaction with Fluid Retention.

Itraconazole may possess a dose-related negative inotropic effect. Transient, asymptomatic decreases in left ventricular ejection fraction were observed with IV administration in healthy volunteers; these resolved before the next infusion. Additionally, cases of congestive heart failure (CHF), peripheral edema, and pulmonary edema have been reported during postmarketing experience in patients treated for onychomycosis and/or systemic fungal infections. Itraconazole should not be used to treat onychomycosis in patients with evidence of ventricular dysfunction such as CHF or history of CHF; itraconazole should not be used for other indications in such patients unless the benefit clearly outweighs the risk. The risks and benefits of itraconazole therapy should be reviewed carefully in patients with risk factors for CHF (including cardiac disease [e.g., ischemic and valvular disease], significant pulmonary disease [e.g., chronic obstructive pulmonary disease], renal failure and other edematous disorders). Patients with risk factors for CHF should be advised of the signs/symptoms of CHF, treated with caution, and monitored for signs/symptoms of CHF during therapy.

Heart Block

Major:

propafenone

Propafenone has a major potential interaction with Heart Block.

The use of propafenone is contraindicated in patients with conduction disorders such as second- or third-degree AV block, right bundle-branch block when associated with a left hemiblock(bifascicular block), sick sinus syndrome, or bradycardia-tachycardia syndrome in the absence of a functional artificial pacemaker.

Major:

propafenone

Propafenone has a major potential interaction with Heart Block.

The use of propafenone is contraindicated in patients with uncontrolled congestive heart failure, cardiogenic shock, bradycardia, or marked hypotension. Propafenone can exacerbate congestive heart failure by beta blockade of sympathetic stimulation necessary for circulatory support. Propafenone also has negative inotropic activity that can depress cardiac output and cardiac index.

Heart Disease

Major:

Sporanox

The itraconazole in Sporanox has a major potential interaction with Heart Disease.

Propafenone has a moderate potential interaction with Hypokalemia.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.

Hypotension

Major:

propafenone

Propafenone has a major potential interaction with Hypotension.

The use of propafenone is contraindicated in patients with uncontrolled congestive heart failure, cardiogenic shock, bradycardia, or marked hypotension. Propafenone can exacerbate congestive heart failure by beta blockade of sympathetic stimulation necessary for circulatory support. Propafenone also has negative inotropic activity that can depress cardiac output and cardiac index.

Immunodeficiency

Moderate:

Sporanox

The itraconazole in Sporanox has a moderate potential interaction with Immunodeficiency.

The oral bioavailability of itraconazole 100-mg capsules may be decreased in some immunocompromised patients (e.g., neutropenic patients, AIDS patients, organ transplant recipients); in addition, since hypochlorhydria has been reported in HIV-infected patients, the absorption of itraconazole may be reduced in these patients. The dose of itraconazole 100-mg capsules should be adjusted based on the clinical response of such patients.

Itraconazole oral solution is not recommended for initial treatment in severely neutropenic patients at immediate risk of systemic candidiasis.

Liver Disease

Major:

Sporanox

The itraconazole in Sporanox has a major potential interaction with Liver Disease.

Limited data are available on the use of oral itraconazole in patients with liver dysfunction. Itraconazole has been associated with rare cases of serious hepatotoxicity (including liver failure and death). Caution is recommended when this drug is used in patients with liver dysfunction; such patients should be carefully monitored during therapy. Treatment with itraconazole is strongly discouraged in patients with elevated or abnormal liver enzymes, with active liver disease, or who had liver toxicity with other drugs unless the situation is serious or life-threatening and the expected benefit exceeds the risk. Liver function monitoring is recommended for patients with preexisting hepatic function abnormalities or those who had liver toxicity with other drugs.

Moderate:

propafenone

Propafenone has a moderate potential interaction with Liver Disease.

Propafenone is extensively metabolized by the liver. The bioavailability of propafenone in patients with normal hepatic function is approximately 3% to 40%, but increases to approximately 70% in patients with severe hepatic impairment. Therapy with propafenone should be administered cautiously and the dosage reduced to 20% to 30% of that given patients with normal hepatic function. Clinical monitoring of cardiac function (ECG) and hepatic function is recommended.

Lupus Erythematosus

Moderate:

propafenone

Propafenone has a moderate potential interaction with Lupus Erythematosus.

Reversible (+) ANA titers have been reported during administration of propafenone. Therapy with propafenone should be administered cautiously in patients with established systemic lupus erythematosus (SLE). Clinical monitoring, including ANA titers, is recommended. Patients without a previous history of (+) ANA titer or SLE who develop a (+) ANA while receiving propafenone should be evaluated and, if ANA titers persist or worsen, discontinuation of therapy should be considered.

Magnesium Imbalance

Moderate:

propafenone

Propafenone has a moderate potential interaction with Magnesium Imbalance.

Electrolyte imbalance can alter the therapeutic effectiveness of antiarrhythmic agents. Hypokalemia and hypomagnesemia can reduce the effectiveness of antiarrhythmic agents. In some cases, these disorders can exaggerate the degree of QTc prolongation and increase the potential for torsade de pointes. Hyperkalemia can potentiate the toxic effects of antiarrhythmic agents. Electrolyte imbalance should be corrected prior to initiating antiarrhythmic therapy. Clinical monitoring of cardiac function and electrolyte concentrations is recommended.
