The short term effects of five second-generation antipsychotics on serum prolactin in the first-episode schizophrenia patients / 中国神经精神疾病杂志

ABSTRACT

Objective To explore the short term effects of five second-generation antipsychotics on the serum pro?lactin levels of first-episode schizophrenia patients. Methods Two hundred fifty first-episode schizophrenia patients were randomly divided into five groups and were then treated with risperidone, olanzapine, paliperidone, quetiapine or ziprasidone, respectively. The serum prolactin were tested at baseline, and every week following initiation of treatment. The positive and negative symptom scale (PANSS) and the treatment emergent symptom scale (TESS) were used to evalu?ate the effect and side effect of treatment. Results Repeated measure ANOVA for serum prolactin showed that the main effects of time, the main effect of group, and the interactive effect of time and group were significant (all P0.05). Conclusion The level of serum prolactin gradually increases in schizophrenia patients receiving treatment of antipsychotics. The short term effects of different second generation antipsy?chotics on serum prolactin vary differently. Risperidol and olanzapine result in the elevation of serum prolactin level in the early period of treatment.
