[Action of trazodone on the secretion of pituitary hormones. Behavior of prolactin and somatotropin].

The effect of i.v. trazpdone on PRL and GH was studied in normal subjects and in patients with hypophyseal adenoma coupled with amenorrhoea and galactorrhoea or acromegaly. PRL levels were reduced, whereas the behaviour of GH was paradoxical. These results suggest that the dopaminergic and serotoninergic systems take part in regulating the secretion of these two hormones. An interesting comparison was made with their behaviour following the administration of bromoergocryptine in the adenoma series.
