Summary
Cholinesterase inhibitors increase acetylcholine at the neuromuscular junction and may reduce or alter the effect of nondepolarizing blockers like cisatracurium, so blockade may be less predictable. Their effect on succinylcholine is potentiation, and anesthetic response in treated patients can be unpredictable.
What this interaction means in plain words
Cisatracurium and Donepezil transdermal 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
Acetylcholinesterase inhibition raises junctional acetylcholine, which competitively opposes nondepolarizing neuromuscular blockade.
What to do
Monitor neuromuscular function with train-of-four and titrate cisatracurium to effect, anticipating higher dose requirements or variable recovery. Inform the anesthesia team of donepezil use before surgery.
