Donepezil transdermal and Vecuronium: moderate interaction.

For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Summary
Cholinesterase inhibitors such as donepezil may prolong or alter the effect of non-depolarizing neuromuscular blockers. During anesthesia, neuromuscular blockade with vecuronium may be less predictable, and recovery may be delayed or antagonized.
What this interaction means in plain words
Donepezil transdermal and Vecuronium 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 acetylcholine at the neuromuscular junction, which opposes non-depolarizing blockade and makes the response to vecuronium unpredictable.
What to do
Tell the anesthesia team about donepezil use before surgery and monitor neuromuscular function with a nerve stimulator. Titrate vecuronium to effect and watch for variable block depth and recovery.
