Summary
Parenteral magnesium sulfate enhances and prolongs neuromuscular blockade from pancuronium. Recovery can be delayed and postoperative respiratory weakness may occur.
What this interaction means in plain words
Magnesium and Pancuronium can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Magnesium belongs to Gastrointestinal Tract; Pancuronium belongs to Musculoskeletal.
Why it happens
Magnesium reduces presynaptic acetylcholine release and decreases postsynaptic sensitivity, adding to nondepolarizing blockade.
What to do
Reduce the neuromuscular blocker dose and monitor with quantitative train-of-four. Ensure full reversal before extubation in patients receiving magnesium.
