Potent synthetic mu-opioid receptor agonist (50-100x more potent than morphine). Rapid onset, short duration IV. Transdermal provides sustained release over 72 hours.
Potent respiratory depressant. Transdermal patch: 12-24 hour onset, variable absorption (shave area, do not cut patches). Controlled substance (Schedule II). Bradycardia. Fever increases absorption rate.
Species-specific contraindications and adverse-reaction reports for ferrets may differ from canine / feline reference data — consult the primary citations listed with each rule.
