Once drugs reach the site of action, therapeutic success is impeded by the nature of fungal infections. fungal growth is slow, yet most antifungal drugs work better in rapidly growing organisms. likewise, most antifungal agents are fungistatic in action, with clearance of infection largely dependent on host response. The antifungal agents essentially assist the host immune system with the fight against the fungus. in general, these drugs are poorly soluble and, therefore, distribution to the site of action is often a problem. The azole antifungal drugs act by inhibiting the synthesis of the sterol components of the fungal membrane. azoles are predominantly fungistatic. they inhibit c 14 α demethylase (a cytochrome p450 [cyp450] enzyme), thereby blocking the demethylation of lanosterol to ergosterol, the principal sterol of fungal membranes.
