A stability-indicating liquid chromatographic (LC) method was developed for the determination of posaconazole in bulk. Chromatographic separation was achieved using an isocratic elution in a reversed-phase system, with a mobile phase composed of methanol-water (75:25, v/v), at 1.0 mL min(-1) flow. Samples were exposed to degradation under thermal, oxidative and acid/basic conditions, and no int...

We prospectively determined the antifungal susceptibility of yeast isolates causing fungemia using the Etest on direct blood samples (195 prospectively collected and 133 laboratory prepared). We compared the Etest direct (24 h of incubation) with CLSI M27-A3 and the standard Etest methodologies for fluconazole, voriconazole, posaconazole, isavuconazole, caspofungin, and amphotericin B. Strains ...

Although there are currently three generations of antifungal azoles on the market, even the third-generation agents show undesirable interactions with human cytochrome P450 (P450) enzymes. CYP46A1 is a cholesterol-metabolizing P450 in the brain that tightly binds a number of structurally distinct azoles. Previously, we determined the crystal structures of CYP46A1 in complex with voriconazole an...

Posaconazole is a potent broad-spectrum triazole antifungal. Little is known about the prevalence and risk factors for low plasma posaconazole concentrations (PPCs). We retrospectively reviewed all adult patients whose PPCs were measured after at least 5 days of treatment between April 2006 and July 2008 at the Hôpital Necker Enfants Malades. A low PPC was defined as a concentration lower than ...

Posaconazole oral suspension, a marketed extended-spectrum triazole with proven efficacy as antifungal treatment and prophylaxis, should be taken with food to maximize absorption. New tablet and capsule formulations have been developed in an attempt to optimize absorption and bioavailability. The aims of this exploratory open-label, partially randomized, 2-part, 4-way, single-dose crossover stu...

BACKGROUND Invasive aspergillosis is an important cause of morbidity and mortality in immunocompromised patients. Current treatments provide limited benefit. Posaconazole is an extended-spectrum triazole with in vitro and in vivo activity against Aspergillus species. METHODS We investigated the efficacy and safety of posaconazole oral suspension (800 mg/day in divided doses) as monotherapy in...

OBJECTIVES The broad-spectrum triazole posaconazole showed promising results in preventing invasive fungal infections (IFIs) in high-risk patients. Concerns rise over the relevance of breakthrough IFIs (bIFIs) and the emergence of azole-resistant strains. The current retrospective analysis was undertaken to evaluate the incidence of bIFIs and to study fungal colonization and resistance followin...

Invasive aspergillosis and candidemia are important causes of morbidity and mortality in immunocompromised and critically ill patients. The triazoles voriconazole, fluconazole, and posaconazole are widely used for the treatment and prophylaxis of these fungal infections. Due to the variability of the pharmacokinetics of the triazoles among and within individual patients, therapeutic drug monito...
