Effect of pimozide on levodopa-induced growth hormone release in man.
Serum growth hormone (GH) behaviour after levodopa administration was measured in twelve healthy subjects both in basal conditions and after a 4 day course of pimozide (4 mg daily), a specific blocker of dopamine (DA) receptors. In addition, fasting plasma GH was measured on the first, second and third day of treatment. No significant difference was found between GH response to levodopa in basal conditions and after pimozide; moreover, fasting GH was uninfluenced by pimozide.
