title: Hyperprolactinemia after low dose of amisulpride.
abstract: OBJECTIVE
  Amisulpride in antipsychotic doses can induce hyperprolactinemia. The aim of this study was to prove whether the same is true for low doses of amisulpride.
  
  
  METHODS
  Plasma prolactin levels were measured in 5 males and 5 females with depressive symptoms who were treated with 50 mg of amisulpride per day as an augmentation to antidepressants (n=5), benzodiazepine anxiolytics (n=8) or in monotherapy (n=1). Six of these patients were assessed prior to onset of amisulpride treatment and after 10 days of amisulpride use. Four patients had been using amisulpride for more than a month.
  
  
  RESULTS
  There was a significant increase of prolactin levels from mean 16+/-6 ng/ml to 113+/-65 ng/ml (median 14.5 ng/ml to median 92 ng/ml; Wilcoxon matched pair test, p=0.027). All patients had hyperprolactinemia (30-200 ng/ml). The prolactinemia was significantly higher in females (mean 160+/-50 ng/ml; median 198 ng/ml) than in males (mean 48+/-12 ng/ml; median 48 ng/ml; Mann-Whitney U test, p=0.041).
  
  
  CONCLUSIONS
  Even low doses of amisulpride used as an augmentation to antidepressant treatment, benzodiazepines or in monotherapy seem to be associated with hyperprolactinemia. The co-medication of antidepressants and benzodiazepines can potentially increase intensity of prolactinemia.
