Summary
Cholinesterase inhibitors such as donepezil may reduce the effect of rocuronium by raising acetylcholine at the end plate, so higher doses or a slower block may be needed. Donepezil may also prolong the action of succinylcholine, although this concerns a different blocker.
What this interaction means in plain words
Donepezil and Rocuronium 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; Rocuronium belongs to Musculoskeletal.
Why it happens
Inhibition of acetylcholinesterase increases synaptic acetylcholine, which competitively opposes the non-depolarizing block of rocuronium.
What to do
Titrate rocuronium using train-of-four monitoring in patients taking donepezil. Expect variable response and reversal requirements.
