Summary
Anticholinergic agents slow gastrointestinal motility, which can increase digoxin absorption, particularly with slow-dissolving tablets. The effect is variable and the combination product is not clearly defined.
What this interaction means in plain words
Anticholinergic / sedative combos and Digoxin 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
Reduced gut motility prolongs dissolution and absorption time of digoxin; the sedative component has no established mechanism.
What to do
Monitor for signs of digoxin toxicity and check digoxin level if anticholinergic therapy is started or stopped.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
