Abstract
To investigate possible central dopaminergic regulation of betaendorphin-like immunoreactivity (βE-LI) and adrenocorticotropin (ACTH) release in humans, we gave the dopamine antagonist haloperidol or placebo intravenously to twelve normal male subjects and measured βE-LI and cortisol for 120 minutes following injection. Haloperidol, but not placebo, produced significant increases in plasma βE-LI and cortisol. These findings suggest that central dopaminergic pathways such as the tuberohypophyseal system may participate in regulation of the secretion of βE and ACTH from the human pituitary.
