Summary
Trimipramine is a tricyclic antidepressant with anticholinergic and quinidine-like properties, and pancuronium has vagolytic activity that raises heart rate. Together they may add to tachycardia and arrhythmia risk, particularly during anesthesia.
What this interaction means in plain words
Pancuronium and Trimipramine 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.
Pancuronium belongs to Musculoskeletal; Trimipramine belongs to Central Nervous System.
Why it happens
Additive anticholinergic (vagolytic) effects of pancuronium and trimipramine, with tricyclic-related sensitization of the myocardium to sympathetic stimulation.
What to do
Monitor ECG and heart rate during anesthesia and consider a less vagolytic neuromuscular blocker in patients with cardiac disease or on higher tricyclic doses. Treat arrhythmias promptly and avoid additional sympathomimetics.
