Summary
Pancuronium given before succinylcholine can reduce or antagonize its depolarizing block, while succinylcholine given first may modify the onset and potency of a later non-depolarizing dose. Net effect varies with the sequence and dose, so response may be unpredictable.
What this interaction means in plain words
Pancuronium and Succinylcholine 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.
Pancuronium belongs to Musculoskeletal; Succinylcholine belongs to Musculoskeletal.
Why it happens
Competing actions at the nicotinic receptor: depolarizing agonist versus competitive antagonist, with possible phase II block.
What to do
Wait until succinylcholine effect has clearly receded before giving pancuronium, and titrate using train-of-four monitoring. Adjust the pancuronium dose to observed response.
