Itralase 200 Capsule contains Itraconazole 200 mg, a broad-spectrum triazole antifungal agent effective against a variety of fungal infections. Itraconazole works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting cell membrane integrity and leading to fungal cell death. It is indicated for the treatment of systemic and superficial mycoses, including aspergillosis, blastomycosis, histoplasmosis, and onychomycosis. Itralase 200 Capsule is suitable for adult patients requiring oral antifungal therapy. The medication should be administered as prescribed by a healthcare professional, with dosage and duration tailored to the specific infection and patient response. Common side effects may include gastrointestinal disturbances such as nausea, vomiting, and abdominal pain, as well as headache and rash. Caution is advised in patients with hepatic impairment or congestive heart failure, and it is contraindicated in patients with known hypersensitivity to itraconazole or other azole antifungals. Itraconazole has potential drug interactions due to its effect on cytochrome P450 enzymes; therefore, concomitant use with certain medications should be avoided or closely monitored. Regular liver function tests and clinical monitoring are recommended during prolonged therapy to ensure safety and efficacy.
