Summary
Donepezil is an acetylcholinesterase inhibitor and can oppose the effect of non-depolarizing blockers such as pancuronium, so a higher dose of the blocker may be needed or recovery may differ from expected. Donepezil may also exaggerate the effect of succinylcholine-type agents, but for pancuronium the main concern is reduced blockade and unpredictable neuromuscular monitoring in patients on chronic therapy.
What this interaction means in plain words
Donepezil 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.
Donepezil belongs to Central Nervous System; Pancuronium belongs to Musculoskeletal.
Why it happens
Pharmacodynamic antagonism: increased synaptic acetylcholine from cholinesterase inhibition competes with pancuronium at nicotinic receptors of the motor endplate.
What to do
Monitor neuromuscular function with train-of-four during anesthesia and titrate pancuronium to effect. Inform the anesthesia team of chronic donepezil use before surgery.
What to ask your pharmacist
