Fentanyl
MOA Adverse Effects: Schedule # of drug: Effect: Contraindications:
Mu opiate agonist (80-100x’s more than morphine)
AE: sedation, constipation, bradyardia, resp. distress, dangerous behavior in horses
Schedule II controlled drug
Effect: Analgesic, Opiate
Contra: chronic use leads to tolerance and dependance

- Schedule II controlled drug
- Analgesic, opiate
- may cause AV block in some patients, cats, horses more sens. to excitement, may cause bradycardia
