Itaspor 200 Capsule contains Itraconazole 200 mg, a broad-spectrum triazole antifungal agent used to treat a variety of 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. Itaspor 200 is indicated for the treatment of systemic and superficial mycoses, including blastomycosis, histoplasmosis, aspergillosis, onychomycosis, and candidiasis. The capsule formulation allows for oral administration, with absorption enhanced when taken with food. It 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. Rare but serious side effects may involve hepatotoxicity and congestive heart failure exacerbation. Itaspor 200 should be used under medical supervision with appropriate monitoring of liver function tests and clinical response. Dosage and duration depend on the type and severity of infection. It is contraindicated in patients with known hypersensitivity to itraconazole or related azoles, and in those taking medications that may cause serious interactions.
