Drug interactions
Moderate drug interactions
Moderate:
itraconazole almotriptan
Applies to: Sporanox (itraconazole) and almotriptan
Itraconazole may increase the blood levels and effects of almotriptan, which in some cases can lead to excessive narrowing of blood vessels in the body. This can reduce blood flow to vital organs and increase the risk of rare but serious side effects such as high blood pressure, heart attack, stroke, and gangrene (death of tissues, usually in the arm or leg, that may require surgical amputation). You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if you experience numbness, tingling, chest pain or tightness, shortness of breath, or irregular heartbeat, as these may be signs and symptoms of excessive almotriptan levels. Do not take larger doses or use the drug more frequently than prescribed. 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.
Disease interactions
28 potential interactions Applies to: 24 conditions, including High Cholesterol, Weight Loss, COPD, Angina, and Menopause.
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.
Angina
Major:
almotriptan
Almotriptan has a major potential interaction with Angina.
The use of 5-hydroxytryptamine receptor (5-HT1) agonists is contraindicated in patients with a history or current symptoms or signs of ischemic coronary artery disease (CAD), coronary artery vasospasm (including Prinzmetal's angina), cerebrovascular syndromes (stroke or TIA), peripheral vascular disease (including ischemic bowel disease), uncontrolled hypertension, and any other significant underlying cardiovascular disease. 5-HT1 agonists can cause vasospastic reactions, including coronary vasospasm, peripheral vascular ischemia, and colonic ischemia. Some serious adverse cardiac events including acute myocardial infarction, arrhythmia, cardiac arrest, and death have been reported within a few hours following the administration of 5-HT1 agonists, in some cases even in patients with no prior history or findings of CAD. Significant elevation in blood pressure, including hypertensive crisis, has also been reported on rare occasions in patients with and without a history of hypertension, as have transient increases in blood pressure and peripheral vascular resistance. Cerebrovascular events have included cerebral hemorrhage, subarachnoid hemorrhage, and stroke, some resulting in fatalities. However, the relationship to 5-HT1 agonists is uncertain and, in a number of cases, the cerebrovascular events may have been primary where symptoms were mistaken to be migraine.
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.
Cardiovascular Conditions and Disorders
Major:
almotriptan

However, the relationship to 5-HT1 agonists is uncertain and, in a number of cases, the cerebrovascular events may have been primary where symptoms were mistaken to be migraine.
COPD
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.
Diabetes Mellitus
Major:
almotriptan
Almotriptan has a major potential interaction with Diabetes Mellitus.
The group of drugs known as 5-hydroxytryptamine1 receptor (5-HT1) agonists can cause vasospastic reactions, including coronary vasospasm, peripheral vascular ischemia, and colonic ischemia. Rarely, serious adverse cardiac events including acute myocardial infarction, arrhythmia, cardiac arrest, and death have been reported within a few hours following the administration of 5-HT1 agonists, in some cases even in patients with no prior history or findings of coronary artery disease (CAD). Significant elevation in blood pressure, including hypertensive crisis, has also been reported on rare occasions in patients with and without a history of hypertension, as have transient increases in blood pressure and peripheral vascular resistance. In general, patients with potentially unrecognized CAD as predicted by the presence of risk factors (e.g., hypertension, hypercholesterolemia, tobacco use, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) should not be administered 5-HT1 agonists unless a cardiovascular evaluation provides satisfactory clinical evidence indicating the lack of CAD, ischemic heart disease, or other significant underlying cardiovascular disease. As a precaution, the manufacturers recommend that the first dose be administered under medical surveillance in such patients, and that electrocardiographic monitoring be considered during the interval immediately following administration to help detect any asymptomatic cardiac ischemia that may occur. Periodic cardiovascular evaluations should be performed during intermittent, long-term use.
Fluid Retention
Major:

Liver Disease
Major:
almotriptan
Almotriptan has a major potential interaction with Liver Disease.
Almotriptan is partially metabolized by the liver. The pharmacokinetics of almotriptan have not been assessed in patients with hepatic impairment. Based on the known mechanisms of clearance of almotriptan, the maximum decrease in clearance expected due to hepatic impairment would be 60%. The manufacturer recommends that a starting dose of 6.25 mg be used in patients with significantly impaired hepatic function, and that the maximum dosage not exceed 12.5 mg per 24-hour period.
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.
