Itranox 100 Capsule contains Itraconazole 100 mg, a broad-spectrum antifungal agent belonging to the triazole class. It is indicated for the treatment of various systemic and superficial fungal infections caused by susceptible strains of fungi, including dermatophytes, yeasts, and molds. Itraconazole exerts its antifungal effect by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. This medication is commonly prescribed for conditions such as onychomycosis, blastomycosis, histoplasmosis, aspergillosis, and candidiasis. Itranox 100 Capsule is administered orally, with absorption enhanced when taken with food. Dosage and duration of therapy depend on the type and severity of the infection, as well as patient-specific factors. Caution is advised in patients with hepatic impairment, and liver function tests should be monitored during prolonged therapy. Itraconazole may interact with several drugs metabolized via the cytochrome P450 system, necessitating careful review of concomitant medications. Common adverse effects include gastrointestinal disturbances, headache, and rash. Itranox 100 Capsule should be used under medical supervision to ensure appropriate use and minimize potential risks.
