Inhibits fungal CYP51 (lanosterol 14-alpha-demethylase), blocking ergosterol synthesis. Broader spectrum than fluconazole including Aspergillus.
Drug of choice for aspergillosis. Hepatotoxic — monitor liver enzymes. Many CYP-mediated drug interactions. Visual disturbances in humans. Non-linear pharmacokinetics in some species.
Species-specific contraindications and adverse-reaction reports for chickens may differ from canine / feline reference data — consult the primary citations listed with each rule.
