    • These patients should be made aware of the symptoms and treatment options for HF.
    • If you notice HF symptoms or signs, discontinue treatment.
    • Post-marketing data showed that HF was more common in patients who received a daily total dose of 400mg, but there were cases among patients who took lower daily doses.
    • Itraconazole, according to the American Heart Association (magnitude : major), may cause underlying myocardial dysfunction (magnitude : major).
    • This should be avoided if you are treating serious fungal infections (AHA [Page 2016,]).
  • Hepatotoxicity:

    • Rare cases of severe hepatotoxicity (including death and liver failure) have been reported. Some cases occurred within the first week of treatment.
    • If you notice signs or symptoms of hepatotoxicity, discontinue treatment.
  • Hypersensitivity

    • Reports of hypersensitivity reactions have been made. If you experience one, stop using the medication and get supportive care.
    • Patients with a history or hypersensitivity to other Azoles should be cautious.
  • Neuropathy:

    • Patients on long-term itraconazole have been known to develop peripheral neuropathy.

Calcium Channel Blockers

Calcium channel blockers' negative/toxic effects may be increased by antifungal agents (systemic azole derivatives). In particular, itraconazole may make verapamil or diltiazem's unfavourable inotropic effects worse. Calcium Channel Blockers' metabolism may be slowed down by antifungal agents (systemic azole derivatives). Fluconazole and isavuconazonium, which are covered in different monographs, probably have less powerful effects than those of other azoles. Treatment: Itraconazole should not be used concurrently with felodipine or nisoldipine. With any such combination, regular monitoring is advised; calcium channel blocker dose decreases might be necessary. Clevidipine is an exception.

See prescribing information or full interaction monograph for details.

Ceritinib

CYP3A4 Inhibitors (Strong) may increase the serum concentration of Ceritinib. Management: If such combinations cannot be avoided, the ceritinib dose should be reduced by approximately one-third (to the nearest 150 mg).

Treatment: Patients receiving the combo drug elvitegravir/cobicistat/emtricitabine/tenofovir should not take more than 200 mg of itraconazole per day for adults. There are no dosage guidelines for other cobicistat-containing medicines.

Colchicine

CYP3A4 Inhibitors (Strong) may increase the serum concentration of Colchicine. Management: Colchicine is contraindicated in patients with impaired renal or hepatic function who are also receiving a strong CYP3A4 inhibitor. In those with normal renal and hepatic function, reduce colchicine dose as directed. See full monograph for details.

Colchicine

The serum concentration of colchicine may rise in response to P-glycoprotein/ABCB1 inhibitors. It's possible that colchicine will distribute more widely throughout some tissues, like the brain. Treatment: Patients receiving a p-glycoprotein inhibitor and having compromised renal or hepatic function should not take colchicine. Colchicine dosage should be decreased in patients with normal renal and hepatic function as instructed. For information, see the entire monograph.

Copanlisib

CYP3A4 Inhibitors (Strong) may increase the serum concentration of Copanlisib. Management: If concomitant use of copanlisib and strong CYP3A4 inhibitors cannot be avoided, reduce the copanlisib dose to 45 mg. Monitor patients for increased copanlisib effects/toxicities.

Refer to the dabigatran labelling or the complete monograph.

Daclatasvir

Daclatasvir's serum levels may rise in response to strong CYP3A4 inhibitors. Treatment: If daclatasvir is coupled with a potent CYP3A4 inhibitor, reduce the dose to 30 mg once day. When administered with darunavir/cobicistat, daclatasvir does not require a dose change.

Management: Increase ECG monitoring frequency if delamanid is combined with strong CYP3A4 inhibitors due to the risk for QTc interval prolongation. Continue frequent ECG assessments throughout full delamanid treatment period. Exceptions discussed separately.

Didanosine

Could reduce how well antifungal agents are absorbed (Azole Derivatives, Systemic). Didanosine capsules with an enteric coating shouldn't have any impact on these antifungals.

DOCEtaxel

Monitoring parameters:

  • Liver function in patients with preexisting hepatic dysfunction, and in all patients as clinically indicated;
  • renal function;
  • signs/symptoms of HF

Monitoring serum trough concentrations is advised for invasive aspergillosis (treatment or prolonged prophylaxis). Since itraconazole has a varied pharmacokinetic profile and high concentrations may raise the risk of adverse effects, it is advisable to monitor serum trough concentrations for other infections.


How to administer Itraconazole (Sporanox)?

Oral:

  • Formulations are not interchangeable; generally, the oral solution is the preferred formulation because of improved absorption.
  • Administer capsule and tablet with a full meal.
  • The oral solution should be taken on an empty stomach; when treating oropharyngeal and esophageal candidiasis, the solution should be swished vigorously in the mouth (10 mL at a time), then swallowed.
  • Swallow capsule whole; do not crush, chew, or break.

Mechanism of action of Itraconazole (Sporanox):

It inhibits cytochrome P450 activity and decreases ergosterol synthesis (principal sterol found in fungal cell membranes).

Absorption

  • Capsule: 100mg Sporanox capsule (Sporanox), requires gastric acidity (absorption increases when taken with food).
  • Tolsura 65 mg capsule (Tolsura 65 mg capsule), has a higher absorption when taken empty stomach. However, Tolsura (2x65 mg capsule) when combined with food can result in exposures similar those experienced when Sporanox (2x100 mg capsule) is taken with food.
  • Oral solution: Absorption increased when empty stomach.
  • Tablet: Prefers gastric acidity. Absorption is increased when taken with food.

Distribution:

  • Plasma concentrations are lower than plasma concentrations because they are highly lipophilic.
  • Concentrations of the highest amount are found in adipose and skin/nails, omentum and endometrium, cervical mucus, vaginal mucus and cervical mucus.
  • The concentrations of aqueous fluids, such as CSF and urine, are negligible. They can be distributed into bronchial exudate or sputum.

Protein binding, plasma:

  • 99.8%; metabolite hydroxy-itraconazole: 99.6%

Metabolism:

  • Extensively hepatic via CYP3A4 into >30 metabolites including hydroxy-itraconazole (major metabolite); appears to have in vitro antifungal activity.
  • The main metabolic pathway is oxidation; may undergo saturation metabolism with multiple dosing.

Bioavailability:

  • Variable, ~55% increases by 30% under fasted conditions (oral solution);
  • Note: The oral solution has a higher degree of bioavailability (149% ± 68%) relative to oral capsules; should not be interchanged

Half-life elimination:

  • Children (6 months to 12 years):
    • Oral solution: ~36 hours;
    • Metabolite hydroxy-itraconazole: ~18 hours
  • Adults: Oral:
    • Single-dose: 16 to 28 hours,
    • Multiple doses: 34 to 42 hours;
    • Cirrhosis (single dose): 37 hours (range: 20 to 54 hours)

Time to peak, plasma:

  • Capsules/tablets: 2 to 5 hours;
  • Oral solution: 2.5 hours

Excretion:

  • Urine (<1% active drug, 35% as inactive metabolites);
  • feces (54%; ~3% to 18% as unchanged drug)
