Itrastar 100mg Capsule contains Itraconazole, a broad-spectrum triazole antifungal agent used to treat a variety of fungal infections. It is effective against infections caused by dermatophytes, yeasts, and molds, including conditions such as onychomycosis, blastomycosis, histoplasmosis, aspergillosis, and candidiasis. Itraconazole works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes, thereby disrupting cell membrane integrity and leading to fungal cell death. The recommended dosage and duration of therapy depend on the type and severity of the infection, and treatment should be guided by a healthcare professional. Itrastar 100mg Capsule is typically administered orally and should be taken with food to enhance absorption. Patients should be monitored for potential side effects, which may include gastrointestinal disturbances, headache, dizziness, and elevated liver enzymes. Caution is advised in patients with hepatic impairment or congestive heart failure. Itraconazole may interact with several medications due to its effect on cytochrome P450 enzymes; therefore, a thorough medication review is essential before initiating therapy. It is contraindicated in patients with known hypersensitivity to itraconazole or other azole antifungals. Proper adherence to prescribed dosing and duration is critical to ensure therapeutic efficacy and reduce the risk of resistance.
