Summary
Volatile anesthetics such as desflurane sensitize the myocardium to catecholamines, and isoproterenol is a potent beta-agonist that increases heart rate and arrhythmia risk. Ventricular arrhythmias and marked blood pressure changes may occur.
What this interaction means in plain words
Desflurane and Isoproterenol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Desflurane belongs to Central Nervous System; Isoproterenol belongs to Respiratory.
Why it happens
Myocardial sensitization to catecholamines by halogenated anesthetics combined with beta-adrenergic stimulation.
What to do
If isoproterenol is required, give it by careful titration with continuous ECG and blood pressure monitoring. Be ready to lighten anesthetic depth and treat arrhythmias.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
