Lantraz 100mg Capsule contains Itraconazole, a broad-spectrum triazole antifungal agent indicated for the treatment of various systemic and superficial fungal infections. Itraconazole exerts its antifungal activity 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. Lantraz is commonly prescribed for infections such as aspergillosis, histoplasmosis, blastomycosis, onychomycosis, and candidiasis, including oropharyngeal and esophageal candidiasis. The recommended dosage and duration of therapy depend on the type and severity of the infection, patient response, and clinical judgment. Lantraz should be administered with food to enhance absorption. Caution is advised in patients with hepatic impairment, congestive heart failure, or those taking concomitant medications that may interact via the cytochrome P450 system, as itraconazole has the potential for significant drug interactions. Common adverse effects include gastrointestinal disturbances, headache, and rash. Liver function tests should be monitored periodically during prolonged therapy. Lantraz 100mg Capsule offers an effective antifungal option when used according to prescribing guidelines and under appropriate medical supervision.
