antifungal agent 

Any substance which destroys or prevents the growth of fungi. It is one of the antibiotic groups. There are several classes of antifungal drugs: Polyenes, which cause an increase in fungal cell wall permeability leading to its death. Examples: amphotericin B, natamycin, nystatin. Azoles, which act either by inhibiting the synthesis of ergosterol, a component of fungal cell wall or by causing direct wall damage. Examples: clotrimazole, econazole, fluconazole, itraconazole, ketoconazole, miconazole. Pyrimidines, which interfere with the normal function of fungal cells. Example: flucytosine. Syn antimycotic agent.
