zinc + fluconazole

Zinc + fluconazole is an experimental or investigational combination of the essential trace element zinc (in various forms such as zinc salt, zinc complex, or zinc oxide) and the antifungal drug fluconazole. There is evidence from in vitro and in vivo studies that the combination can exert synergistic antifungal effects against species of Candida, including *Candida albicans* and *Candida glabrata*. Fluconazole, a triazole antifungal, acts by inhibiting fungal cytochrome P450 sterol 14α-demethylase (CYP51), thereby blocking ergosterol biosynthesis, a key component of fungal cell membranes. Zinc may potentiate this effect via several mechanisms, including direct antifungal activity, disruption of fungal cell membrane integrity, and enhanced permeability to fluconazole when used as zinc complexes or in nanoparticle form (e.g., zinc oxide quantum dots). The combination has shown reduced minimal inhibitory concentrations (MIC) for various Candida species compared to fluconazole alone, and can inhibit fungal biofilm formation and filamentation. However, clinical data for this specific combination as a marketed or approved therapy is lacking, and most reports relate to experimental use, topical formulations, or metal-drug complex studies[3][4].
