Indications & Clinical Uses

Itraconazole is a triazole antifungal that interferes with fungal cell membrane synthesis, making it effective against several systemic mycoses.

  • Invasive aspergillosis: treatment of life‑threatening lung infection caused by Aspergillus species.
  • Candidiasis (oropharyngeal and esophageal): eradication of Candida infections in the mouth and esophagus.
  • Dermatophytosis: clearance of skin infections caused by dermatophyte fungi.
  • Blastomycosis: resolution of infection caused by Blastomyces dermatitidis.
  • Histoplasmosis: management of disease due to Histoplasma capsulatum.
  • Sporotrichosis: therapy for infection by Sporothrix schenckii.

How It Works

  • Itraconazole inhibits the fungal enzyme lanosterol 14α‑demethylase, a cytochrome P450 isoform essential for converting lanosterol to ergosterol. By blocking ergosterol synthesis, the drug disrupts fungal cell membrane integrity, leading to impaired growth and eventual cell death.

Side Effects

Common Side Effects

  • Nausea: mild to moderate stomach upset.
  • Headache: transient cranial discomfort.
  • Rash: skin irritation or mild erythema.
  • Elevated liver enzymes: mild, often reversible increase.

Serious or Rare Side Effects

  • Hepatotoxicity: severe liver injury requiring monitoring.
  • Stevens‑Johnson syndrome: rare but severe skin reaction.
  • Cardiac failure: worsening of pre‑existing heart conditions.
  • Visual disturbances: blurred vision or photophobia.
  • Severe allergic reactions: anaphylaxis or angioedema.

Precautions & Warnings

Itraconazole requires careful monitoring due to its potential impact on liver function and drug interactions.

  • Assess liver function: obtain baseline tests and repeat periodically.
  • Review concomitant medications: check for known interactions before prescribing.
  • Monitor cardiac status: use cautiously in patients with heart failure.
  • Avoid use in pregnancy: potential fetal risk, discuss alternatives.
  • Store at room temperature: keep in the original pack, protect from moisture and light.

Avoid Interactions

Itraconazole interacts with many medicines that affect hepatic metabolism or share toxicity pathways.

Major Interactions (Avoid)

  • Rifampin: markedly reduces itraconazole exposure.
  • Ketoconazole: additive hepatotoxic risk.
  • Erythromycin: increases itraconazole levels, risk of toxicity.
  • St. John’s wort: induces metabolism, lowering efficacy.
  • Other azole antifungals (e.g., voriconazole): may cause excessive plasma concentrations.

Moderate Interactions (Monitor Closely)

  • Warfarin: may raise INR, require coagulation monitoring.
  • Simvastatin: increased risk of myopathy, consider dose adjustment.
  • Oral contraceptives: reduced effectiveness, advise backup contraception.

Frequently Asked Questions

Itraconazol Stada contains itraconazole, which is prescribed for serious fungal infections such as invasive aspergillosis, oropharyngeal and esophageal candidiasis, dermatophytosis, blastomycosis, histoplasmosis, and sporotrichosis. The drug targets the fungal cell membrane, helping to clear the infection when used under medical supervision.

Itraconazole blocks the fungal enzyme lanosterol 14α‑demethylase, a key step in ergosterol synthesis. Without ergosterol, the fungal cell membrane becomes unstable, inhibiting growth and leading to cell death. This mechanism makes itraconazole effective against a broad range of pathogenic fungi.

The dosage of Itraconazol Stada is determined by the prescribing clinician based on the specific infection, patient weight, age, renal and hepatic function, and other clinical factors. Only a qualified health professional can set the appropriate regimen.

Safety data for itraconazole in pregnancy are limited, and the drug is generally avoided unless the benefit outweighs potential risk. It is also excreted in breast milk, so breastfeeding mothers should discuss alternatives with their health care provider.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Itraconazole belongs to the triazole class, offering oral convenience and broad-spectrum activity. Compared with polyenes like amphotericin B, itraconazole has fewer infusion‑related reactions but shares hepatic metabolism risks. Azoles such as fluconazole have a narrower spectrum, while newer agents like voriconazole may provide better coverage for certain molds but can have higher cost.

Itraconazol Stada should be stored at room temperature, below 25 °C, in its original packaging. Keep the product away from moisture, direct sunlight, and excessive heat to maintain stability throughout its shelf life.

The medication is taken orally, usually with a full glass of water. Depending on the formulation, it may be recommended to take it with food to improve absorption, but patients should follow the specific instructions provided by their prescriber.

Serious risks include hepatotoxicity, severe skin reactions such as Stevens‑Johnson syndrome, and worsening of heart failure. Patients should be monitored for signs of liver injury, skin changes, or cardiac symptoms, and the drug should be discontinued if these occur.

Individuals with known hypersensitivity to itraconazole or any component of the formulation should avoid the product. It is also contraindicated in patients with severe liver disease, uncontrolled heart failure, or those taking medications that cause dangerous interactions without appropriate monitoring.
