Prolactin responses to d-fenfluramine (d-FEN) challenge (0.5 mg/kg PO) were examined after pre-treatment with and without the 5-HT3 receptor antagonist ondansetron (16 mg PO) in 11 physically healthy male volunteers. Compared to pretreatment with placebo, pre-treatment with ondansetron did not significantly attenuate the PRL response to d-FEN challenge. These data are consistent with other data suggesting little role for 5-HT3 receptors in the PRL response to 5-HT agonist challenge in human subjects.
