Summary
Giving two nondepolarizing neuromuscular blockers together can produce additive or unpredictable blockade. The depth and duration of paralysis may exceed what either drug would cause alone, and the effect depends on the order of administration.
What this interaction means in plain words
Atracurium 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.
Atracurium belongs to Musculoskeletal; Pancuronium belongs to Musculoskeletal.
Why it happens
Both agents competitively antagonize acetylcholine at postsynaptic nicotinic receptors at the neuromuscular junction, producing additive blockade.
What to do
Avoid combining where possible, or reduce the dose of the second agent and monitor with train-of-four. Confirm full recovery before extubation.
