Influence of naloxone on prolactin secretion in patients with acute and chronic renal failure

Abstract

The influence of the opiate antagonist naloxone on chlorpromazine induced prolactin secretion was examined in 12 patients with acute renal failure (ARF), 12 patients with chronic renal failure (CRF) and in 12 healthy subjects. In all examined groups naloxone showed a suppressive effect on chlorpromazine induced prolactin secretion, which was more accentuated in normals and patients with ARF then with CRF. The results of these investigations suggest that endogenous opiates may be of importance in the regulation of prolactin secretion both in normals and uremic patients.
