Summary
Echothiophate is an irreversible cholinesterase inhibitor used in the eye, and systemic absorption can lower cholinesterase activity. This chiefly prolongs succinylcholine, whereas it may shorten or oppose the effect of nondepolarizing agents like rocuronium, making the response less predictable.
What this interaction means in plain words
Echothiophate iodide and Rocuronium 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
Cholinesterase inhibition raises acetylcholine at the neuromuscular junction and antagonizes competitive nondepolarizing blockade.
What to do
Tell the anesthesia team about echothiophate use before surgery, and titrate rocuronium using train-of-four monitoring. Avoid succinylcholine in these patients.
What to ask your pharmacist
