Summary
Both are non-depolarizing neuromuscular blockers, so giving them together produces additive or synergistic muscle paralysis. This can lead to prolonged blockade and delayed recovery of respiratory function.
What this interaction means in plain words
Rapacuronium 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
Additive competitive antagonism of acetylcholine at the nicotinic receptors of the neuromuscular junction.
What to do
Avoid combining two non-depolarizing blockers where possible and titrate dosing using quantitative train-of-four monitoring. Ensure ventilatory support until full recovery is confirmed.
