Posaconazole hydrate is a broad-spectrum, second generation, triazole compound with antifungal activity. | [in vivo]
Treatment of infected animals with amiodarone alone reduces parasitemia, increases survival 60 days pi (0% for untreated controls vs 40% for amiodarone-treated animals) and, when given in combination with Posaconazole, delays the development of parasitemia[1]. Coadministration of Posaconazole and Boost Plus increases drug exposure compared to the administration of Posaconazole alone in the fasted state. Food, particularly meals high in fat content, significantly increases Posaconazole bioavailability. Systemic exposure to Posaconazole increases 4- and 2.6-fold when it is consumed with a high-fat and nonfat meal, respectively[3]. Posaconazole and Amiodarone may constitute an effective anti-T. cruzi therapy with low side effect[4]. At twice-daily doses of ≥ 15 mg/kg of body weight, Posaconazole prolongs the survival of the mice and reduces tissue burden[5]. | [storage]
