Summary
Cholinesterase inhibitors such as donepezil may reduce the effect of nondepolarizing blockers like atracurium by increasing acetylcholine at the junction, though they can also prolong succinylcholine-type blockade. The result is unpredictable neuromuscular blockade during anesthesia.
What this interaction means in plain words
Atracurium 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
Inhibition of acetylcholinesterase raises junctional acetylcholine, pharmacodynamically opposing competitive nondepolarizing blockade.
What to do
Inform the anesthesiologist of donepezil use and monitor neuromuscular function with train-of-four, adjusting atracurium dosing accordingly.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
