Condition(s) targeted: Insulin Resistance; Dyslipidemia
Intervention: olanzapine (Drug); Haloperidol (Drug)
Phase: N/A
Status: Completed

Summary
We hypothesized that short-term treatment with AP drugs induces insulin resistance through a
mechanistic route that is independent of weight gain and that atypical drugs exert stronger
effects than typical compounds in this respect. We therefore treated healthy non-obese men
with olanzapine (atypical AP) or haloperidol (typical AP) for 8 days, and studied the impact
of these interventions on glucose and lipid metabolism by hyperinsulinemic euglycemic clamp,
isotope dilution technology and indirect calorimetry.
