Summary
Atropine may slightly increase atenolol absorption by slowing gastric emptying and gut motility. This is unlikely to be clinically important. Atropine's heart rate raising effect may partly counter atenolol's bradycardia.
What this interaction means in plain words
Atenolol and Atropine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Atenolol belongs to Cardiovascular; Atropine belongs to Miscellaneous.
Why it happens
Anticholinergic slowing of gastrointestinal transit may modestly increase atenolol absorption.
What to do
