Summary

This study tests whether two medications, amitriptyline and trifluoperazine, can reduce stomach symptoms in people with functional dyspepsia—a condition where the stomach feels upset without a clear cause. About 120 adults will take one of the drugs or stick with standard treatment for 8 weeks, then be monitored for 4 more weeks. Researchers will track symptom changes and any side effects.

What this could mean

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

Active substance
amitriptyline and trifluoperazine
What this could lead to
If successful, this could point toward a new treatment option for people with functional dyspepsia who don't get enough relief from standard care.
What could go wrong
This is a mid-stage trial with only 120 participants, so results may not apply to everyone. Both drugs can cause side effects like drowsiness or dizziness.
