Clinical needs for novel antifungal agents have altered steadily with the rise and fall of AIDS-related mycoses, and the change in spectrum of fatal disseminated fungal infections that has accompanied changes in therapeutic immunosuppressive therapies. The search for new molecular targets for antifungals has generated considerable research using modern genomic approaches, so far without generating new agents for clinical use. Meanwhile, six new antifungal agents have just reached, or are approaching, the clinic. Three are new triazoles, with extremely broad antifungal spectra, and three are echinocandins, which inhibit synthesis of fungal cell wall polysaccharides – a new mode of action. In addition, the sordarins represent a novel class of agents that inhibit fungal protein synthesis. This review describes the targets and mechanisms of action of all classes of antifungal agents in clinical use or with clinical potential. Le fluconazole est un agent antifongique bis-triazolé utilisable par voies orale et injectable intraveineuse. Le fluconazole agit en inhibant la biosynthèse de l'ergostérol d'origine fongique. Il est plus spécifique de la synthèse des stérols des champignons que de celle des stérols des mammifères. L'activité in vivo du fluconazole paraît nettement plus marquée que ne le laissent éventuellement prévoir les tests in vitro. Espèces habituellement sensibles : Candida et en particulier albicans, Cryptococcus neoformans. Espèces habituellement résistantes : Candida kruzeï, dermatophytes (microsporum, trichophyton), Aspergillus sp.

It was initially approved by the FDA in 1990. Ghannoum MA, Rice LB Antifungal agents mode of action, mechanisms of resistance, and correlation of these mechanisms with bacterial resistance. In this review, the mode of action of antifungals and their mechanisms of resistance are discussed. However, analysis after 90 min of incubation revealed thatC. krusei accumulated 60% less fluconazole than didC. albicans, implicating active efflux in the fluconazole resistance expressed by these C. It is active against most dermatophytes including epidermophyton, trichophyton, microsporum but not against Candida and other fungi causing mycosis. It is fungistatic in nature. It interferes with mitosis-multinucleated and stunned fungal hyphae result from its action. Itraconazole has a broader spectrum of activity than fluconazole (but not as broad as voriconazole or posaconazole). In particular, it is active against Aspergillus, which fluconazole is not. It is also licensed for use in blastomycosis, sporotrichosis, histoplasmosis, and onychomycosis. Itraconazole is over 99% protein-bound and has virtually no penetration into cerebrospinal fluid. Therefore, it should not be used to treat meningitis or other central nervous system infections. It is also prescribed for systemic infections, such as aspergillosis, candidiasis, and cryptococcosis, where other antifungal drugs are inappropriate or ineffective. Itraconazole has also recently been explored as an anticancer agent for patients with basal cell carcinoma, non-small cell lung cancer, and prostate cancer. Read the Patient Information Leaflet if available from your pharmacist before you start taking fluconazole and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food as directed by your doctor, usually once daily. If you are taking the liquid suspension form of this medication, shake the bottle well before each dose. Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Dosage is based on your medical condition and response to treatment. Generally in children, the dose should not exceed 600 milligrams daily unless directed by the doctor.

Recent trends in the discovery, development and evaluation of. Pharmacology. Mode of action. Like other imidazole- and triazole-class antifungals, fluconazole inhibits the fungal cytochrome P450 enzyme 14α-demethylase. Mammalian demethylase activity is much less sensitive to fluconazole than fungal demethylase. This inhibition prevents the conversion.
