Summary
Aminoglycosides have intrinsic neuromuscular blocking activity and can potentiate non-depolarizing blockers. Systemic absorption from inhaled tobramycin is low, so the effect is usually small but possible in patients with renal impairment or high doses.
What this interaction means in plain words
Tobramycin inhaled and Vecuronium 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
Aminoglycoside reduces presynaptic acetylcholine release and postsynaptic sensitivity, adding to non-depolarizing blockade.
What to do
Monitor neuromuscular blockade with train-of-four and reduce vecuronium dosing as needed, particularly in renal impairment. Watch for delayed recovery.
