Summary
Cholinesterase inhibitors such as donepezil can reduce the effect of non-depolarizing neuromuscular blockers like pancuronium. Onset of blockade may be less predictable and recovery may be altered. This matters mainly around anesthesia.
What this interaction means in plain words
Memantine-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.
Memantine-donepezil belongs to Central Nervous System; Pancuronium belongs to Musculoskeletal.
Why it happens
Increased acetylcholine at the neuromuscular junction competes with non-depolarizing blockade.
What to do
Inform the anesthesia team of donepezil use and monitor neuromuscular blockade with a nerve stimulator. Adjust the blocker dose to the observed response.
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?
