Summary
Rapacuronium is a non-depolarizing neuromuscular blocker with some vagolytic and muscarinic effects, so adding atropine may increase heart rate and heighten tachycardia. The interaction is mainly additive on cardiac muscarinic receptors rather than on neuromuscular blockade.
What this interaction means in plain words
Atropine and Rapacuronium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive muscarinic blockade, particularly of cardiac M2 receptors.
What to do
Monitor heart rate and blood pressure during anesthesia and adjust atropine dosing if marked tachycardia occurs.
