Oropharyngeal candidiasis, a common fungal infection in people living with HIV/AIDS (PLWHA), arises from Candida species colonizing the oral cavity. Fluconazole is the preferred treatment and is often used empirically. Few studies have investigated the prevalence of fluconazole resistance in Nigeria. This study aimed at determining the burden of fluconazole resistance among Candida species in t...

Onychomycosis is a common nail disorder thought to occur in approximately 7-9% of the North American population.v" Until quite recently, there was a paucity of effective and safe therapies for onychomycosis, particularly pedal disease. Griseofulvin was the first significant oral antifungal agent to become available for the treatment of onychomycosis.v? Since then, other oral antifungal agents h...

We studied fluconazole penetration in the brain in five patients who had a deep cerebral tumor whose removal required the excision of healthy brain tissue. Plasma and brain samples were simultaneously obtained after oral ingestion of 400 mg of fluconazole daily for 4 days (90% of steady state). Fluconazole penetration in healthy cerebral parenchyma was determined. Plasma and brain samples were ...

The goal of the study was to test the assumption that a competitive inhibition constant determined in vivo, Kiiv, like its corresponding in vitro counterpart, Ki, is independent of inhibitor concentration. Inhibition of the CYP2C9-dependent formation of (S)-7-hydroxy-warfarin from (S)-warfarin was measured in seven healthy subjects at three different doses of fluconazole. Prothrombin time measu...

The allosteric effect of fluconazole (effector) on the formation of 1'-hydroxymidazolam (1'-OH-MDZ) and 4-hydroxymidazolam (4-OH-MDZ) from midazolam (MDZ), a substrate of CYP3A4/5--members of the cytochrome P450 superfamily of enzymes--was examined in healthy volunteers. Following pretreatment with fluconazole, the ratio of the areas under the curve (AUCs) for 4-OH-MDZ and MDZ (AUC(4-OH)/AUC(MD...

Fluconazole disk-diffusion susceptibility was evaluated in 230 blood isolates and 344 non-blood clinical isolates of Candida spp. collected in 2002 at National Taiwan University Hospital. Up to 93.5% of blood isolates were susceptible to fluconazole, 3% were susceptible dose-dependent, and 3.5% were resistant. The minimum inhibitory concentrations at which 50% of tested isolates were inhibited ...

BACKGROUND Candida guilliermondii has been recognized as an emerging pathogen showing a decreased susceptibility to fluconazole and considerably high echinocandin MICs. AIMS Evaluate the in vitro activity of anidulafungin in comparison to amphotericin B and fluconazole against different isolates of C. guilliermondii, and their efficacy in an immunosuppressed murine model of disseminated infec...

The echinocandin class of antifungal agents is considered to be the first-line treatment of bloodstream infections (BSI) due to Candida glabrata. Recent reports of BSI due to strains of C. glabrata resistant to both fluconazole and the echinocandins are of concern and prompted us to review the experience of two large surveillance programs, the SENTRY Antimicrobial Surveillance Program for the y...

Candida albicans is responsible for most fungal infections in humans. Fluconazole is well established as a first-line management option for the treatment and prophylaxis of localized and systemic C. albicans infections. Fluconazole exhibits predictable pharmacokinetics and is effective, well tolerated and suitable for use in most patients with C. albicans infections, including children, the eld...

The combination of lactoferrin with fluconazole has been reported to synergistically enhance the antifungal activity of fluconazole against Candida spp. and inhibit the hyphal formation in fluconazole-resistant strains of Candida albicans. In this study, we investigated the association between the therapeutic effects of this combination and the pharmacological characteristics of fluconazole and...
