Summary
Systemic atropine blocks muscarinic receptors and counteracts the effects of bethanechol. Bethanechol efficacy is lost, and atropine is in fact used to reverse excessive cholinergic effects from bethanechol.
What this interaction means in plain words
Atropine iv / and Bethanechol 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
Competitive muscarinic receptor antagonism by atropine opposes the direct agonist action of bethanechol.
What to do
Avoid routine co-administration because the effects cancel out. Keep atropine available to treat bethanechol cholinergic toxicity.
