Could a Parkinson's drug fix antipsychotic side effects?
NCT ID NCT03575000
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This small pilot study tests whether bromocriptine, a drug used for Parkinson's, can safely improve blood sugar problems in people with schizophrenia who have prediabetes from antipsychotic medications. Fifteen adults will take bromocriptine for 6 weeks, with researchers monitoring safety, blood sugar, and psychiatric symptoms. The goal is to see if it's worth studying further as a way to prevent type 2 diabetes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
bromocriptine (a dopamine agonist pill)
What this could lead to
If it works, this could point toward a safe, cheap way to prevent or delay type 2 diabetes in people with schizophrenia who take antipsychotics.
What could go wrong
This is a very small, early pilot study with only 15 people and no placebo group. It focuses on safety, not proof of effectiveness, so results may not lead to a treatment.
