Itraconazole is an antifungal medication used to treat a variety of fungal infections. It is available by prescription in oral capsule and oral solution forms, as well as an intravenous solution [1].
What fungal infections does itraconazole treat?
Itraconazole is prescribed for infections such as blastomycosis, histoplasmosis, and aspergillosis, and it can also be used to treat fungal infections of the nails [1]. It is effective against a broad spectrum of fungi, including yeasts and molds [2].
How does itraconazole work?
Itraconazole belongs to a class of drugs called triazole antifungals. It works by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes. This disruption leads to increased membrane permeability and ultimately cell death [3].
Where can I buy itraconazole?
Itraconazole is a prescription medication, meaning it can only be obtained with a valid prescription from a healthcare provider. Once you have a prescription, you can purchase it at most retail pharmacies [1]. Online pharmacies also offer itraconazole, but it is essential to ensure they are legitimate and require a prescription [4].
What is the difference between itraconazole capsules and solution?
The oral capsule and oral solution forms of itraconazole have different absorption rates. The oral solution is generally better absorbed than the capsules, especially when taken with food [1]. For certain indications, like nail fungus, the absorption characteristics are important for treatment efficacy [3].
When does the patent for itraconazole expire?

How does itraconazole compare to other antifungals?
Itraconazole is effective against a wide range of fungal pathogens, but its use can be limited by potential drug interactions and side effects. Other antifungal classes, such as azoles (e.g., fluconazole, voriconazole) and echinocandins, are also used depending on the specific infection and patient profile [2].
