Summary
Anticholinergics can add to the motor benefit of levodopa but may worsen dyskinesia, including tardive dyskinesia, and cause confusion. At higher doses they slow gastric emptying and may delay levodopa absorption.
What this interaction means in plain words
Atropine and Carbidopa-entacapone-levodopa have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Atropine belongs to Miscellaneous; Carbidopa-entacapone-levodopa belongs to Central Nervous System.
Why it happens
Anticholinergic effects delay gastric emptying, increasing gastric degradation of levodopa, and pharmacodynamically modify basal ganglia cholinergic-dopaminergic balance.
What to do
Monitor for reduced levodopa response, dyskinesia and cognitive effects, and use the lowest effective anticholinergic dose.
