Itrostred 100 Capsule contains Itraconazole 100 mg, a broad-spectrum triazole antifungal agent used for the treatment of various fungal infections. Itraconazole exerts its antifungal activity by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. Itrostred 100 is indicated for the management of systemic and superficial mycoses, including aspergillosis, histoplasmosis, blastomycosis, onychomycosis, and candidiasis. The capsule formulation allows for convenient oral administration with good bioavailability when taken with food. Dosage and duration of therapy depend on the type and severity of infection, and treatment should be guided by clinical response and microbiological findings. Caution is advised in patients with hepatic impairment, and periodic liver function monitoring is recommended during prolonged therapy. Itrostred 100 may interact with several drugs metabolized via the cytochrome P450 system, necessitating careful review of concomitant medications to avoid adverse effects or reduced efficacy. Common adverse reactions include gastrointestinal disturbances, headache, and rash. This medication should be used under medical supervision, with adherence to prescribed dosing to ensure optimal therapeutic outcomes and minimize resistance development.
