Introduction Posaconazole is an azole used in treatment and prophylaxis of a broad spectrum of fungal infections. Antifungals such as ketoconazole have been shown to cause primary adrenal insufficiency (AI) as a result of direct inhibition on the steroidogenesis pathway. There is only one reported case of primary AI induced by posaconazole in a patient with mucormycosis. We report a case of pos...

Posaconazole (Noxafil, SCH 56592), an orally available broad-spectrum triazole antifungal, is currently in phase III clinical studies for treating serious opportunistic fungal infections. The major in vitro metabolite of posaconazole formed by human liver microsomes supplemented with uridine 5'-diphosphate-glucuronic acid was a glucuronide of posaconazole (m/z877). Screening of 10 cDNA-expresse...

BACKGROUND Voriconazole and posaconazole are used prophylactically against invasive fungal infection (IFI) in patients with acute myeloid leukaemia (AML). The current study attempted to evaluate the economics of voriconazole versus posaconazole for prophylaxis in AML. METHODS A 6 year (2003-09) retrospective chart review of AML patients was performed at a major Australian tertiary hospital. P...

Posaconazole is an orally bioavailable triazole antifungal agent for the treatment and prophylaxis of invasive fungal infection. We evaluated plasma posaconazole concentration data from juvenile (younger than 18 years; n = 12) and adult (18 to 64 years; n = 194) patients who participated in a multicenter, phase 3, open-label study that assessed the efficacy and safety of posaconazole treatment ...

INTRODUCTION Posaconazole is superior to fluconazole (FLU) and itraconazole (ITRA) in the prevention of invasive fungal diseases (IFDs) in neutropenic patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). A new tablet formulation of posaconazole with improved pharmacokinetic and pharmacodynamic properties compared to posaconazole oral solution has recently been appr...

Presently, therapy of eumycetoma in Sudan is still based on surgery combined with prolonged ketoconazole therapy. This usually results in a poor clinical outcome. To determine if posaconazole and terbinafine could offer better therapeutic alternatives, the in vitro susceptibilities of 34 Madurella mycetomatis strains were determined. It appeared that posaconazole was highly active against M. my...

The new antifungal derivative posaconazole was tested against three clinical isolates of Cryptococcus neoformans var. neoformans using a broth microdilution procedure performed according to the guidelines established by the NCCLS. Posaconazole MICs were 0.125, 0.25 and 1.0 mg/L for isolates 491, 2337 and 486, respectively. To investigate the in vivo activity of this new compound, we established...

Invasive aspergillosis due to azole-resistant Aspergillus fumigatus is difficult to manage. We describe a case of azole-resistant invasive aspergillosis in a female bottlenose dolphin, who failed to respond to voriconazole and posaconazole therapy. As intravenous therapy was precluded, high dose posaconazole was initiated aimed at achieving trough levels exceeding 3 mg/l. Posaconazole serum lev...

OBJECTIVES Posaconazole is an extended-spectrum triazole with proven efficacy as antifungal treatment and prophylaxis. The marketed oral suspension should be taken with food to maximize systemic absorption. A new solid oral tablet has been developed with improved bioavailability that can be administered without regard to food. The aim of this study was to evaluate rising single- and multiple-do...
