Inhibits lanosterol 14-alpha-demethylase (CYP51), blocking ergosterol synthesis in fungal membranes. At high doses, inhibits adrenal and gonadal steroidogenesis.
Hepatotoxic — monitor liver enzymes. Strong CYP inhibitor (many drug interactions). Requires gastric acid for absorption (do not give with antacids). Also used for Cushing's disease (adrenal steroidogenesis inhibition).
Species-specific contraindications and adverse-reaction reports for ferrets may differ from canine / feline reference data — consult the primary citations listed with each rule.
