Buspirone 47-70 prolactin Homo sapiens 15-18 2274641-3 1990 completely suppressed the maximal PRL response to buspirone challenge. Buspirone 50-59 prolactin Homo sapiens 34-37 2274641-4 1990 Pretreatment with the nonselective beta-adrenergic/5-HT1-like antagonist, pindolol suppressed the maximal PRL response to buspirone challenge depending upon dose (i.e., between 49 to 90% suppression at best dose). Buspirone 122-131 prolactin Homo sapiens 106-109 2274641-5 1990 In personality disorder patients, PRL responses to buspirone challenge correlated inversely with self-assessed "irritability" (r = -.76, n = 10, p less than .01). Buspirone 51-60 prolactin Homo sapiens 34-37 2274641-6 1990 These data suggest that the PRL response to buspirone challenge reflects the responsivity of 5-HT1a receptors in the limbic-hypothalamus in humans and that reduced sensitivity of these receptors is associated with an important component of impulsive aggressive behaviors in personality disorder patients.
