Abstract:
The purposes of this study were to compare the difference of prolactin responses to risperidone and haloperidol, the sex difference in prolactin responses to each drug and the difference of prolactin responses to both drug in each sex. METHODS: The patients with schizophrenia, schizophreniform disorder, schizoaffective disorder, delusional disorder, brief psychotic disorder diagnosed by the criteria of DSM-IV were randomly assigned to risperidone group (n=18) or haloperidol group (n=15). Prolactin levels were measured before drug administration and at week 1, 2, 3, 4, 6 after drug administration by immunoradiometric assay. RESULTS: Prolactin levels after risperidone administration were significantly (p<0.05) higher than those after haloperidol. There was no sex difference in the prolactin responses to haloperidol administration. As for risperidone administration, female showed significantly (p<0.05) higher prolcatin levels than male. There was no difference of prolactin responses to both drugs in male, but in female, prolactin levels after risperidone administration were significantly (p<0.05) higher than those after haloperidol. CONCLUSION: Compared to haloperidol, risperidone can cause significantly higher prolactin response in female than male. Therefore one should consider whether there is a sexual side effects related to the elevated prolactin level especially in female during risperidone administration.
