Abstract
The neuroendocrine and behavioral responses to the potent mu opiate receptor agonist Fentanyl (FE) have been systematically investigated in healthy male volunteers. These volunteers received, according to a randomized block design, different doses of FE: 0.1 mg/70 kg (n = 11), 0.2 mg/70 kg (n = 11), 0.25 mg/70 kg (n = 8), and saline (n = 11). FE induced a pronounced dose-dependent increase of plasma prolactin concentrations, which was significant at the lowest dose. In contrast, growth hormone was significantly stimulated by the highest FE dose only. Moreover, FE induced a maximum reduction of plasma cortisol concentrations at the lowest dose (0.1 mg/70 kg). In parallel, marked euphoric responses were also observed at this lowest FE dose. These results suggest a mu specific influence on all neuroendocrine and behavioral parameters investigated. Different responses of these parameters to different doses of FE, however, suggest a differential modulation of these parameters by the mu receptor agonist FE.
