Summary
Oral neomycin can be absorbed, particularly with bowel damage or renal impairment, and aminoglycosides have neuromuscular blocking activity. This can intensify and prolong pancuronium paralysis, with a risk of apnea.
What this interaction means in plain words
Neomycin po 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.
Why it happens
Aminoglycosides reduce presynaptic acetylcholine release and postsynaptic sensitivity, adding to nondepolarizing blockade.
What to do
Monitor with train-of-four and keep ventilatory support available until full recovery. Reduce pancuronium dosing if needed, especially in renal impairment.
