Summary

Anticholinergics such as glycopyrronium slow gastrointestinal motility, which may modestly increase metformin absorption and exposure. The effect is usually small and clinically minor in most patients.

What this interaction means in plain words

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

Glycopyrronium belongs to Respiratory; Metformin belongs to Endocrine.

Evidence level: Low

Why it happens

Reduced gastrointestinal motility from antimuscarinic action may prolong metformin absorption; the evidence for this is limited.

What to do

No routine dose change is needed; monitor glycemic control and gastrointestinal tolerance if glycopyrronium is started or stopped.
