Which is an antifungal agent?
Azole Antifungal Drugs The clinically useful imidazoles are clotrimazole, miconazole, and ketoconazole. Two important triazoles are itraconazole and fluconazole. In general, the azole antifungal agents are thought to inhibit cytochrome P450-dependent enzymes involved in the biosynthesis of cell membrane sterols.
Why are antifungals used in commercial agriculture?
Moreover, antifungal drugs used in agriculture can serve as environmental drivers for the development of drug-resistant fungal strains [18]. To decrease the development of drug resistance of fungi in fields, the use of a mix of antifungals with different action mechanisms is encouraged [16,17].
How are antifungal agents classified?
Antifungals can be grouped into three classes based on their site of action: azoles, which inhibit the synthesis of ergosterol (the main fungal sterol); polyenes, which interact with fungal membrane sterols physicochemically; and 5-fluorocytosine, which inhibits macromolecular synthesis.
What are the types of antifungal?
Common names for antifungal medicines include:
- clotrimazole (Canesten)
- econazole.
- miconazole.
- terbinafine (Lamisil)
- fluconazole (Diflucan)
- ketoconazole (Daktarin)

What are antifungal drugs give the classification with example?
There are two subgroups of azole antifungals: imidazoles and triazoles. Examples of imidazole antifungals and the conditions they treat are: Ketoconazole: infections of the skin and hair, Candida infections of the skin and mucous membranes, blastomycosis, histoplasmosis. Clotrimazole: skin and mucous membrane …
What is antifungal drug with example?
Types of antifungal Of the clinically employed azole antifungals, only a handful are used systemically. These include ketoconazole, itraconazole, fluconazole, fosfluconazole, voriconazole, posaconazole, and isavuconazole. Examples of non-azole systemic antifungals include griseofulvin and terbinafine.
What are the three main types of fungi?
The three major groups of fungi are:
- Multicellular filamentous moulds.
- Macroscopic filamentous fungi that form large fruiting bodies.
- Single celled microscopic yeasts.
What are examples of fungicides?
Sulfur, sulfur-containing compounds, organic salts of iron, and heavy metals are all used as fungicides. Other fungicide types include carbamates or thiocarbamates such as benomyl and ziram, thiozoles such as etridiazole, triazines such as anilazine, and substituted organics such as chlorothalonil.
How many antifungal drugs are there?
In the United States, only 10 antifungal drugs are currently approved by the Food and Drug Administration (FDA) for the therapy of systemic fungal infections. As shown in table 1, these drugs belong to 3 principal classes: polyenes, pyrimidines, and azoles.

What is the mode of action of antifungal drugs?
The mode of action is obscure. Apart from side effects like altered estrogen levels and liver damage, many antifungal medicines can cause allergic reactions in people. For example, the azole group of drugs is known to have caused anaphylaxis . There are also many drug interactions.
Can oral antifungals treat nail fungus?
Before oral antifungal therapies are used to treat nail disease, a confirmation of the fungal infection should be made. Approximately half of suspected cases of fungal infection in nails have a non-fungal cause.
