Posaconazole is an antifungal from the triazole group . It inhibits ergosterol biosynthesis and has been on the market since October 2005 under the trade name Noxafil (Essex Pharma). Posaconazole is currently considered an antifungal agent to be used in severe or itraconazole or amphotericin B- resistant fungal infections, especially in immunocompromised patients. It is also currently only approved for the treatment of adults. In other patients or uncomplicated fungal infections, the azoles itraconazole and fluconazole continue to be the first choice.

Scedosporium apiospermum and Sporothrix species show gaps in their effectiveness .

pharmacology

Posaconazole inhibits 14 α- demethylase, a fungus-specific cytochrome P450 isoenzyme ( CYP51A1 ) which is responsible for the conversion of lanosterol into ergosterol . Ergosterol precursors are built into the membrane and the permeability for cell components increases.
