OBJECTIVE Amphotericin B failure is frequently seen in patients with candidaemia caused by Candida rugosa. We evaluated amphotericin B, fluconazole, posaconazole and voriconazole as alternative treatments against infection in mice with two isolates of C. rugosa. METHODS Neutropenic mice were inoculated intravenously with C. rugosa. Amphotericin B, fluconazole, posaconazole and voriconazole we...

OBJECTIVES During extracorporeal membrane oxygenation (ECMO), drug disposition changes significantly. Plasma concentrations are altered due to an expanded circulating volume leading to a decreased elimination. In addition, adsorption and sequestration of drugs by the ECMO circuit components may further alter pharmacokinetics. Treating patients during the ECMO period with antifungals is difficul...

We investigated the antifungal activities of itraconazole and voriconazole on Aspergillus species by time kill studies, and the results were compared with those obtained for Candida species. Exposure of Aspergillus fumigatus conidia to varying concentrations (1.25 to 10 microg/ml) of itraconazole and voriconazole resulted in cellular death; the cytocidal effect was time and concentration depend...

Reversed phase high performance liquid chromatographic method was developed and validated for the estimation of voriconazole in bulk and formulation using prominence diode array detector. Selected mobile phase was a combination of water:acetonitrile (35:65 % v/v) and wavelength selected was 256 nm. Retention time of voriconazole was 3.95 min. Linearity of the method was found to be 0.1 to 2 mug...

The in vitro activity of voriconazole was compared with that of itraconazole and fluconazole against 181 isolates of Candida albicans, 124 isolates of Candida glabrata, and 20 isolates of Candida krusei obtained from the early 1980s through the mid-1990s. Voriconazole had greater intrinsic activity than fluconazole or itraconazole against all three Candida species. For C. glabrata, C. krusei, a...

BACKGROUND Voriconazole is a new antifungal agent that has been recently introduced into clinical practice. We found no published reports of painful peripheral neuropathy associated with its use. OBJECTIVE To describe a unique case of painful peripheral neuropathy associated with voriconazole use. SETTING University hospital. PATIENT A 43-year-old patient who had undergone liver transplan...

Fungal keratitis is one of the major causes of ophthalmic mycosis and is difficult to treat. The range of common antifungal agents available for fungal keratitis remains inadequate and is generally associated with poor clinical outcomes. Voriconazole is a new generation triazole antifungal agent. Only marketed in systemic formulation and, with broad-spectrum activity and high intraocular penetr...

INTRODUCTION Amphotericin B, azole or sulfamide drugs are used for treatment of patients with paracoccidioidomycosis. Among the azole drugs, voriconazole was active in vitro against Paracoccidioides brasiliensis and showed efficacy in the treatment of patients infected with this fungus.In the present study the antifungal activity of voriconazole and of other drugs was compared in a rat model of...

INTRODUCTION Voriconazole and posaconazole are often used to treat invasive Aspergillus infections. We describe a patient with chronic pulmonary aspergillosis (CPA) who experienced peripheral eosinophilia and eosinophilic colitis while on voriconazole, and also experienced gastrointestinal symptoms and recurrent eosinophilia while on subsequent posaconazole therapy. CASE PRESENTATION A 75-yea...
