Effects of nalbuphine on anterior pituitary and adrenal hormones and subjective responses in male cocaine abusers.

Nalbuphine (Nubain) is a mixed action mu-kappa agonist used clinically for the management of pain. Nalbuphine and other mu-kappa agonists decreased cocaine self-administration in preclinical models. Cocaine stimulates the hypothalamic-pituitary-adrenal (HPA) axis, but the effects of nalbuphine on the HPA axis are unknown.

Alcohol effects on hCG-stimulated gonadal hormones in women.

Chronic alcohol abuse is associated with derangements of reproductive function in women. The mechanism of increased risk for alcohol-related abortions and fetal alcohol syndrome is unknown. The goal of this study was to determine if acute alcohol administration affected gonadal steroid hormone levels after administration of human chorionic gonadotropin (hCG) to normal healthy women.

Alcohol effects on LH and FSH in ovariectomized female monkeys.

The acute effects of alcohol (2.5, 3.0, 3.

Naltrexone effects on pituitary and gonadal hormones in male and female rhesus monkeys.

The long-acting opioid antagonist, naltrexone, stimulates LH and FSH in women during the early follicular phase of the menstrual cycle and is a new provocative test of hypothalamic-pituitary function (42,63). The acute effects of naltrexone (0.25, 0.
