Summary
Anticholinergics can improve some parkinsonian symptoms but may slow gastric emptying and reduce levodopa absorption. They may also worsen dyskinesia, confusion or other anticholinergic effects. Glycopyrrolate crosses the blood-brain barrier poorly, so central effects are limited.

Carbidopa-entacapone-levodopa and Glycopyrronium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
