Stomach acid drug may change how schizophrenia medication works

NCT ID NCT07262736

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at how a common stomach acid drug, pantoprazole, affects the levels of clozapine, a medication for schizophrenia. Thirty-three healthy volunteers took clozapine alone and again after several days of pantoprazole. Researchers measured drug concentrations in the blood to see if pantoprazole changes clozapine exposure, which could help personalize dosing in the future.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

clozapine and pantoprazole

What this could lead to

If successful, this study could help doctors adjust clozapine doses more safely when patients also take pantoprazole, reducing side effects or treatment failure.

What could go wrong

This is a small, early-phase trial in healthy volunteers, not patients. Results may not directly apply to people with schizophrenia or other medical conditions.
