Fluconazole

They inhibit the fungal cytochrome P450 enzyme ‘lanosterol 14-demethylase’ and thus impair ergosterol synthesis leading to a cascade of membrane abnormalities in the fungus.
lower affinity for mammalian CYP450 enzymes and lesser propensity to inhibit mammalian sterol synthesis – causes less side effects
It is a water-soluble triazole having a wider range of activity
Indications include cryptococcal meningitis, systemic and mucosal candidiasis in both normal and immunocompromised patients, coccidioidal meningitis and histoplasmosis
