Sporanox PulsePak (itraconazole) Disease Interactions
There are 5 disease interactions with Sporanox PulsePak (itraconazole):
Itraconazole (Includes Sporanox PulsePak) ↔ Chf
Severe Potential Hazard, High plausibility
Applies to: Renal Dysfunction, Fluid Retention, Heart Disease, Chronic Obstructive Pulmonary Disease
Itraconazole may possess a dose-related negative inotropic effect. Transient, asymptomatic decreases in left ventricular ejection fraction have been observed following intravenous administration in healthy volunteers. Additionally, cases of congestive heart failure (CHF), peripheral edema, and pulmonary edema have been reported during postmarketing use for onychomycosis and/or systemic fungal infections. Therapy with itraconazole should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as CHF or a history of CHF. It is also not recommended for other indications in such patients unless benefit clearly outweighs the risk. Cautious use is advised in patients with risk factors for CHF, including cardiac disease such as ischemic and valvular disease; significant pulmonary disease such as chronic obstructive pulmonary disorder; and renal disease and other edematous disorders. These patients should be informed of and monitored for signs and symptoms of CHF during treatment.

Itraconazole (Includes Sporanox PulsePak) ↔ Hepatotoxicity
Severe Potential Hazard, Low plausibility
Applies to: Liver Disease
The use of itraconazole has been rarely associated with hepatotoxicity. Reversible idiosyncratic hepatitis and fatalities have been reported, the latter occurring primarily in patients with serious underlying medical conditions and taking multiple concomitant medications. Liver function tests should be performed periodically in patients with preexisting hepatic abnormalities, particularly when itraconazole therapy is administered continuously for more than one month. Therapy should be withdrawn if persistent elevations or worsening of liver enzyme levels occur. Because itraconazole is also extensively metabolized by the liver, patients with liver disease should be monitored carefully during treatment with itraconazole, and the dosing adjusted or discontinued if necessary.

Azole Antifungals (Includes Sporanox PulsePak) ↔ Qt Prolongation
Moderate Potential Hazard, Moderate plausibility
Applies to: Long QT Syndrome, Arrhythmias
Most of the azole antifungals have been associated with prolongation of the QT interval. There have been postmarketing rare reports of QT prolongation, and torsade de pointes usually involving patients with 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. Concomitant use with other medications that have potential to increase the risk of cardiotoxicity should be avoided.
Itraconazole (Includes Sporanox PulsePak) ↔ Achlorhydria
Moderate Potential Hazard, High plausibility
Applies to: Achlorhydria
The absorption of itraconazole from the capsule formulation diminishes with decreased gastric acidity. Patients with achlorhydria should be advised to take itraconazole capsules with 8 oz. of a cola beverage, which has been shown to enhance absorption in AIDS patients with relative or absolute achlorhydria.

Itraconazole (Includes Sporanox PulsePak) ↔ Renal Dysfunction
Moderate Potential Hazard, Moderate plausibility
Applies to: Renal Dysfunction
Limited data are available on the use of oral itraconazole in patients with renal impairment. Caution is advised when using itraconazole in these patients. A dose reduction may be needed.
