Itradan 100 Capsule contains Itraconazole 100 mg, a broad-spectrum triazole antifungal agent indicated for the treatment of various fungal infections. 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 effective against a wide range of dermatophytes, yeasts, and molds, including Candida species, Aspergillus species, and dermatophytes responsible for infections such as onychomycosis, tinea corporis, tinea pedis, and tinea cruris. Additionally, Itraconazole is used in the management of systemic mycoses such as histoplasmosis, blastomycosis, and aspergillosis. The recommended dosage and duration of therapy depend on the type and severity of the infection, and it is essential to adhere to prescribed treatment regimens to achieve optimal therapeutic outcomes. Itradan 100 Capsule should be taken with food to enhance absorption. Caution is advised in patients with hepatic impairment, congestive heart failure, or those receiving concomitant medications metabolized by the cytochrome P450 system due to potential drug interactions. Common adverse effects include gastrointestinal disturbances, headache, and rash. Liver function tests should be monitored periodically during prolonged therapy.
