I-Win 100 Capsule contains Itraconazole 100 mg, a broad-spectrum antifungal agent belonging to the triazole class. It is indicated for the treatment of various fungal infections including blastomycosis, histoplasmosis, aspergillosis, and onychomycosis, as well as other systemic and superficial mycoses caused by susceptible fungi. 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. The capsule formulation ensures optimal bioavailability when taken with food, enhancing absorption. I-Win 100 is typically administered orally once or twice daily, depending on the severity and type of infection. Dosage adjustments may be necessary in patients with hepatic impairment or those receiving concomitant medications that interact with the cytochrome P450 enzyme system, particularly CYP3A4. Common adverse effects include gastrointestinal disturbances such as nausea, vomiting, and abdominal pain, as well as headache and dizziness. Liver function tests should be monitored during prolonged therapy due to potential hepatotoxicity. I-Win 100 is contraindicated in patients with known hypersensitivity to itraconazole or other azole antifungals and should be used cautiously during pregnancy. Proper medical supervision is essential to ensure efficacy and safety.
