Condition(s) targeted: Insulin Resistance; Dyslipidemia

Intervention: Haloperidol (Drug)

Phase: N/A

Status: Completed

Sponsored by: Leiden University Medical Center


We hypothesized that short-term treatment with haloperidol induces insulin resistance through a mechanistic route that is independent of weight gain. We therefore treated healthy non-obese men with haloperidol for 8 days, and studied the impact of these intervention on glucose and lipid metabolism by hyperinsulinemic euglycemic clamp, isotope dilution technology and indirect calorimetry.
