Synthetic corticosteroid with potent mineralocorticoid activity promoting sodium retention and potassium excretion at the distal tubule. Also has glucocorticoid activity.
Monitor electrolytes (Na/K ratio). Dose escalation over time is common. May cause PU/PD, weight gain, hypertension. Used for hypoadrenocorticism (Addison's).
Species-specific contraindications and adverse-reaction reports for ferrets may differ from canine / feline reference data — consult the primary citations listed with each rule.
