Itraneed 100 Capsule contains Itraconazole 100 mg, a broad-spectrum triazole antifungal agent indicated for the treatment of various systemic and superficial fungal infections. Itraconazole exerts its antifungal effect by inhibiting the cytochrome P450-dependent enzyme lanosterol 14-α-demethylase, which is essential for the conversion of lanosterol to ergosterol, a critical component of fungal cell membranes. This disruption leads to increased membrane permeability and ultimately fungal cell death. Itraneed 100 Capsule is effective against infections caused by dermatophytes, yeasts, and molds, including conditions such as onychomycosis, blastomycosis, histoplasmosis, aspergillosis, and candidiasis. The capsule formulation ensures adequate bioavailability when taken with food, facilitating optimal absorption. Dosage and duration of therapy should be individualized based on the type and severity of infection, patient response, and clinical judgment. Caution is advised in patients with hepatic impairment, congestive heart failure, or those receiving concomitant medications metabolized via the cytochrome P450 system due to potential drug interactions. Common adverse effects include gastrointestinal disturbances, headache, and rash. Regular monitoring of liver function tests is recommended during prolonged therapy. Itraneed 100 Capsule should be used under medical supervision to ensure safe and effective treatment outcomes.
