Abstract
Endogenous and exogenous opiate-like compounds have been found to cause increased serum growth hormone and prolactin levels in animals, and, in some cases, humans. Naloxone, a relatively specific narcotic antagonist, decreases serum prolactin and growth hormone levels in animals. Naloxone (20 mg IV) did not significantly alter serum prolactin levels and, minimally but not significantly, increased growth hormone levels in humans to whom it was administered.
