Answer

The azoles are a group of synthetic antimycotic agents with a broad spectrum of activity. The primary drugs available include ketoconazole, miconazole, fluconazole, itraconazole, and econazole. The mechanism of action of azoles is blocking the synthesis of ergosterol, the primary sterol in the fungal cell membrane. The depletion of ergosterol alters the fluidity of the cell membrane and alters the action of the membrane-associated enzymes. This results in inhibition of replication and inhibition of the transformation of candidal yeast forms into hyphae, which is the invasive and pathogenic form of the parasite.

Nystatin and amphotericin are polyenes, which are active against some fungi but have little action on mammalian cells and no action on bacteria. They bind to cell membranes and interfere with permeability and transport functions. These antibiotics act as ionophores and cause leakage of cations.
