Antifongiques azolés

Les imidazolés sont historiquement les premiers antifongiques azolés qui ont été utilisés, Du fait de leur mauvaise absorption digestive et de leur hépatotoxicité, leur utilisation de nos jours se fait principalement par voie locale pour les mycoses superficielles touchant principalement les phanères, la peau ou les muqueuses,

List of Azole antifungals

Azole antifungals work by inhibiting the cytochrome P450 dependent enzyme lanosterol 14-alpha-demethylase, which converts lanosterol to ergosterol, the main sterol in the fungal cell membrane, Depletion of ergosterol damages the cell membrane resulting in cell death, Azole antifungal agents can be used to treat fungal infections of the body and skin, including athlete’s foot, onychomycosis

AN OVERVIEW OF AZOLE ANTIFUNGALS

AN OVERVIEW OF AZOLE ANTIFUNGALS, Abstract, Fungal infections in critically ill or immunosuppressed patients were increasing in incidence in the human population over the last 1-2 decades, There were few advances in antifungal therapy and, until recently, there were few choices from which to select a treatment for systemic mycoses,

Azole antifungal agents

The discovery of the antifungal activity of azole compounds represented an important therapeutic advance, Miconazole, ketoconazole, and fluconazole are currently commercially available, and itraconazole has undergone extensive clinical evaluation, Because of …

Current and Emerging Azole Antifungal Agents

The azole antifungal agents in clinical use contain either two or three nitrogens in the azole ring and are thereby classified as imidazoles e,g,, ketoconazole and miconazole, clotrimazole or triazoles e,g,, itraconazole and fluconazole, respectively, With the exception of ketoconazole, use of the imidazoles is limited to the treatment of superficial mycoses, whereas the triazoles have a

Role of azoles in antifungal therapy

The addition of itraconazole and fluconazole to the antifungal armamentarium has resulted in less toxic, easily administered therapy for both endemic and opportunistic mycoses, Itraconazole has become the treatment of choice for most patients with mild-to-moderate histoplasmosis, blastomycosis, and … Role of azoles in antifungal therapy Clin Infect Dis, 1996 May;22 Suppl 2:S148-53, doi: 10

Overview

Azoles: Mode of Antifungal Action and Resistance

For some azoles, their antifungal mode of action is not only characterized by inhibition of ergosterol biosynthesis, Recently, it was shown that generation of reactive oxygen species ROS is important for the antifungal activity of miconazole, pointing to an ancillary mode of action for this azole, We further analysed the effect of other azole antifungals on ROS generation in Candida albicans

Interactions métaboliques des antifongiques azolés

Azoles are generally metabolised through these systems and may also be concerned by such DDI rifampicin, protease inhibitors, But, as CYP3A4 inhibitors, an enzymatic metabolic pattern widely used by many drugs, azoles result in numerous moderate to severe DDI, Immunosuppressive drugs are especially concerned, i,e,, tacrolimus and cyclosporine calcineurin inhibitors as well as everolimus and

Antifongiques: classes thérapeutiques, mécanismes d’action

Epidemiologic surveys have permitted to establish risk factors associated to resistance to antifungal drugs, A selective pressure due to overprescription of azoles is one of the main factors, Intense immunodepression and prolonged neutropenic status play a major role as well, Analyses of molecular mechanisms of resistance to drugs of the azole group has notably progressed: an overexpression of
