Itrazole 100 Capsule contains Itraconazole 100 mg, a broad-spectrum triazole antifungal agent used for the treatment of various fungal infections. Itraconazole works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting membrane integrity and leading to fungal cell death. It is indicated for the treatment of systemic and superficial mycoses, including aspergillosis, blastomycosis, histoplasmosis, onychomycosis, and candidiasis. Itrazole 100 Capsule is administered orally and exhibits good bioavailability when taken with food, enhancing its absorption. The drug is metabolized primarily by the liver via the cytochrome P450 system, necessitating caution in patients with hepatic impairment and potential drug interactions. Common adverse effects include gastrointestinal disturbances such as nausea, vomiting, and abdominal pain, as well as headache and dizziness. Serious adverse reactions are rare but may include hepatotoxicity and congestive heart failure in susceptible individuals. Itrazole 100 Capsule should be used under medical supervision, with dosage adjustments based on the type and severity of infection. Regular monitoring of liver function tests is recommended during prolonged therapy. It is contraindicated in patients with known hypersensitivity to itraconazole or other azole antifungals.
