Summary
Zotepine has anticholinergic properties, so combining it with glycopyrronium may increase antimuscarinic effects and slow gut motility. The claimed reduction in absorption or antipsychotic effect is not well established.
What this interaction means in plain words
Glycopyrronium and Zotepine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive antimuscarinic effects; slowed gastric emptying could alter zotepine absorption but this is not well established.
What to do
Monitor for constipation, urinary retention and tachycardia, and review the antipsychotic response. Reduce the antimuscarinic dose if gastrointestinal hypomotility develops.
What to ask your pharmacist
