Summary
Neostigmine enhances parasympathetic activity and slows the heart, and pindolol blocks beta-adrenergic stimulation of the heart. The combination can cause additive bradycardia or AV block, especially in patients with conduction disease.
What this interaction means in plain words
Neostigmine and Pindolol 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 pharmacodynamic effects on heart rate and AV conduction through cholinesterase inhibition and beta-adrenergic blockade.
What to do
Monitor heart rate and ECG when neostigmine is given to patients taking pindolol. Have atropine or glycopyrrolate available to treat symptomatic bradycardia.
