title: Use of naltrexone as a provocative test for hypothalamic-pituitary hormone function.
abstract: Naltrexone (50 mg) administration to normal adult women during the early follicular phase of the menstrual cycle (day 1 to day 4 following onset of menstruation) induced a significant elevation in plasma LH, prolactin, ACTH and cortisol levels. Orally administered naltrexone appears to be a safe and effective compound for assessing function of the hypothalamic-anterior pituitary axis in women.
