Summary
Donepezil is a cholinesterase inhibitor and can antagonize nondepolarizing blockers like pancuronium, producing resistance to blockade. It may also exaggerate the effect of succinylcholine, and cause bradycardia.
What this interaction means in plain words
Donepezil transdermal and Pancuronium 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.
Why it happens
Inhibition of acetylcholinesterase increases acetylcholine at the end plate, opposing competitive neuromuscular blockade.
What to do
Monitor train-of-four and adjust pancuronium dosing, and monitor heart rate for bradycardia perioperatively.
