Summary
Isoflurane may sensitize the heart to catecholamines, so dopamine may provoke arrhythmias and blood pressure instability, although isoflurane is less arrhythmogenic than older agents like halothane. Isoflurane vasodilation also modifies the dopamine dose-response.
What this interaction means in plain words
Dopamine and Isoflurane can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dopamine belongs to Cardiovascular; Isoflurane belongs to Central Nervous System.
Why it happens
Volatile anesthetic sensitization of myocardium to catecholamines and altered vascular tone.
What to do
Titrate dopamine carefully with continuous ECG and blood pressure monitoring.
What to ask your pharmacist
