Summary
Donepezil can prolong or alter the response to neuromuscular blockers. Its cholinesterase inhibition may reduce the effect of nondepolarizing blockers such as atracurium, causing unpredictable neuromuscular blockade during anaesthesia.
What this interaction means in plain words
Atracurium and Memantine-donepezil 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.
Atracurium belongs to Musculoskeletal; Memantine-donepezil belongs to Central Nervous System.
Why it happens
Acetylcholinesterase inhibition raises acetylcholine at the neuromuscular junction, opposing nondepolarizing blockade.
What to do
Inform the anaesthetist about donepezil use and monitor neuromuscular function with a nerve stimulator, adjusting the blocker dose 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?
