The neuroendocrinological profile of roxindole, a dopamine autoreceptor agonist, in schizophrenic patients.

abstract：RATIONALE:Asenapine, a psychopharmacologic agent developed for schizophrenia and bipolar disorder, has higher affinity for 5-HT(2A/C,6,7) and alpha(2) adrenergic receptors than for D(2) receptors. Asenapine exhibits potent antipsychotic-like effects without inducing catalepsy, increases cortical and subcortical dopamin...
