약물 상호작용

• Anesthetics, Opiates, Sedative/Hypnotics: Effects may be additive; dosage reduction of one or both agents may be required. General anesthetic requirements may be reduced between 30-60%.
• Atropine, Glycopyrrolate: Can significantly increase arterial blood pressure and heart rate; use together is not recommended in dogs due to increased cardiac workload.
• Epinephrine: Possesses alpha agonist effects; do not use to treat cardiac effects caused by dexmedetomidine.
• Yohimbine: May reverse the effects, but atipamezole is preferred for clinical use.
