Summary
Both are nondepolarizing neuromuscular blockers, so combined use produces additive or prolonged paralysis. Rapacuronium has been withdrawn from most markets, so the combination is rarely relevant in practice.
What this interaction means in plain words
Pancuronium and Rapacuronium 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
Additive competitive antagonism of nicotinic acetylcholine receptors at the neuromuscular junction.
What to do
Monitor neuromuscular function with train-of-four stimulation and reduce the dose of the second agent accordingly. Ensure ventilatory support until full recovery.
