What is Posaconazole?

Posaconazole is a broad-spectrum, second generation, triazole compound with antifungal activity. Posaconazole strongly inhibits 14-alpha demethylase, a cytochrome P450-dependent enzyme. Inhibition of 14-alpha-demethylase prevents the conversion of lanosterol to ergosterol, an important component of the fungal cell wall. Inhibition of ergosterol synthesis changes the fungal cell membrane composition and integrity, alters membrane permeability and eventually leads to fungal cell lysis. Compared to other azole antifungals, posaconazole is a significantly more potent inhibitor of sterol 14-alpha demethylase. (Source: NCI Thesaurus (NCIt))

Posaconazole Uses And Synthesis

Posaconazole is a potent triazole antifungal agent used in the prevention of invasive fungal infections due to aspergillosis and candida in high risk patients. Posaconazole therapy is associated with transient, asymptomatic serum aminotransferase elevations and is a suspected but rare cause of clinically apparent acute drug induced liver injury.

Posaconazole  Clinical Use

-Invasive aspergillosis
-Fusarium infection
-Chromoblastomycosis and mycetoma
-Oropharyngeal candidosis
-Prophylaxis of invasive fungal infections in patients at serious risk
-With the exception of oropharyngeal candidosis and prophylaxis, use is presently restricted to patients with disease that is refractory to other antifungal drugs, or who are intolerant to them.
