Which drug is used as antifungal in pharmacognosy?
Amphotericin B, an effective but relatively toxic drug, has long been the mainstay of antifungal therapy for invasive and serious mycoses.
What is the mechanism of action for antifungal drugs?
The two main mechanisms of action of antifungals targeting the cell wall are related to the inhibition of chitin and β-glucan synthesis. In the period between 2001 and 2006, the echinocandin class of drugs, represented by caspofungin, micafungin, and anidulafungin, was developed.
Is clotrimazole fungicidal or fungistatic?
Azole drugs such as miconazole, clotrimazole, and ketoconazole are fungistatic, limiting fungal growth but depending on epidermal turnover to shed the still-living fungus from the skin surface.
What are antifungal drugs give the classification with example?
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.
Is fluconazole an azole?
Azole antifungal agents have added greatly to the therapeutic options for treatment of systemic fungal infections. The azoles that are available for systemic use can be classified into two groups: the triazoles (fluconazole, itraconazole, voriconazole, posaconazole, and isavuconazole) and the imidazoles (ketoconazole).
Is clotrimazole an azole?
Two topical azole antifungal agents, miconazole and clotrimazole, were introduced in 1969; this was followed by the introduction of econazole in 1974 (109) and a parenteral formulation of miconazole in the late 1970s (21, 103).

Is flucytosine an antifungal?
Antimetabolite antifungals • Flucytosine [floo-SYE-toe-seen] (5-FC) is a synthetic pyrimidine antimetabolite that is often used in combination with amphotericin B. • This combination of drugs is administered for the treatment of systemic mycoses and for meningitis caused by • C. neoformans and • C. albicans. 22
What is the antifungal spectrum of amphotericin B?
Antifungal spectrum: • Amphotericin B is either fungicidal or fungistatic, depending on the organism and the concentration of the drug.
