    Fluconazole mode of action


    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.

Fluconazole is a triazole antifungal agent. Its primary mode of action is the inhibition of fungal cytochrome P-450-mediated 14 alpha-lanosterol demethylation, an essential step in fungal ergosterol biosynthesis. Marriott MS, Richardson K.

    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.

    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. Itraconazole has a broader spectrum of activity than fluconazole. The mechanism of action of itraconazole is the same as the other azole antifungals. Fig. 1.

    OBJECTIVE To determine whether long term doxycycline improves symptoms in patients with chronic seronegative or reactive arthritis. METHODS A randomised, triple blind, controlled clinical trial of three months' treatment with doxycycline or placebo of patients with chronic reactive or seronegative arthritis was conducted. The primary study end points were three month pain and functional status measured by a self administered Arthritis Impact Measurement Scales version 2 (AIMS2) quality of life questionnaire. Secondary end points were pain and functional status at 6–12 months, three month rheumatologist assessed joint count, pain, and arthritis activity, and treatment efficacy in those with previous exposure to chlamydia. RESULTS Of 60 patients randomly allocated to receive doxycycline or placebo, results from 37 were evaluable at three months. Groups were well balanced for major prognostic variables. Doxycycline had no detectable effect at three months on pain change scores (mean difference 1.5, 95% CI −1.2 to 4.2, p=0.25) or composite functional change scores (mean difference 0.8, 95% CI −5.6 to 7.1, p=0.81).
