Posaconazole tablets, a new oral formulation of posaconazole, can be effective when given as antifungal prophylaxis to neutropenic patients at high risk for invasive fungal infection (e.g., those with acute myelogenous leukemia or myelodysplastic syndrome). Such effectiveness might be specifically important to patients with poor oral intake because of nausea, vomiting, or chemotherapy-associate...

A simple, rapid, and sensitive method for the detection of posaconazole using dispersive liquid-liquid microextraction (DLLME) coupled to surface-assisted laser desorption/ionization mass spectrometric detection (SALDI/MS) was developed. After the DLLME, posaconazole was detected using SALDI/MS with colloidal gold and α-cyano-4-hydroxycinnamic acid (CHCA) as the co-matrix. Under optimal extract...

Posaconazole is a commonly used medication for antifungal prophylaxis in patients with high-risk acute leukemia, such as acute myeloid leukemia. Despite clinical data that show that posaconazole is superior to other antifungal prophylaxis medications, posaconazole is known to have many side effects and drug-drug interactions. We present a patient who developed rhabdomyolysis after being started...

We have evaluated the efficacy of posaconazole, amphotericin B, and itraconazole in a murine model of disseminated infection by Fonsecaea monophora. Of these three antifungal drugs tested, posaconazole prolonged survival significantly and reduced the fungal load in most of the organs tested. Bioassay studies demonstrated the relationship between posaconazole levels and dose escalation in serum ...

OBJECTIVES To manage the interaction between fosamprenavir/ritonavir and posaconazole, we hypothesized that ritonavir can be replaced by posaconazole as an alternative booster of fosamprenavir with no significant influence on posaconazole pharmacokinetics. METHODS This was an open-label, randomized, three period, cross-over, single-centre trial in 24 healthy volunteers. All subjects received ...

Background. Posaconazole has a broad spectrum antifungal activity and it may be useful for salvage antifungal treatment for invasive fungal infection (IFI). The aim of this study was to evaluate the efficacy and outcomes of posaconazole salvage treatment (ST) in patients with IFI who were intolerant or refractory to other antifungal therapy with utilization of posaconazole oral suspension (os) ...

Posaconazole is a potent broad-spectrum azole antifungal agent in clinical development for the treatment of invasive fungal infections. This study evaluated the potential for a pH-dependent pharmacokinetic interaction between posaconazole and an antacid (Mylanta), under fasting and nonfasting conditions. Twelve men completed this randomized, four-period crossover, single-dose study. Subjects re...

BACKGROUND Posaconazole is effective as primary antifungal prophylaxis of invasive fungal diseases in patients with acute myeloid leukemia. DESIGN AND METHODS The impact of primary antifungal prophylaxis administered during front-line chemotherapy for acute myeloid leukemia was evaluated by comparing 58 patients who received oral amphotericin B (control group) to 99 patients who received oral...

Cladophialophora bantiana is associated with central nervous system infection and a poor outcome. C. bantiana tends to be resistant to amphotericin B. Accordingly, we evaluated amphotericin B and three triazoles--posaconazole, itraconazole, and fluconazole--for treatment of C. bantiana infection in mice. In immunosuppressed ICR mice infected intravenously, posaconazole, itraconazole, and amphot...
