Summary
Echothiophate is an ophthalmic irreversible cholinesterase inhibitor that can be absorbed systemically and reduces plasma cholinesterase. It would be expected to oppose vecuronium, a non-depolarizing blocker, and make neuromuscular blockade less predictable. Its major anesthetic concern is prolonged succinylcholine action rather than vecuronium.
What this interaction means in plain words
Echothiophate iodide 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
Irreversible acetylcholinesterase inhibition raises acetylcholine at the neuromuscular junction and may antagonize non-depolarizing blockade.
What to do
Inform the anesthesia team of echothiophate use and monitor neuromuscular function with a nerve stimulator. Titrate vecuronium to effect and avoid succinylcholine where possible.
