File 1. Demographic characteristics of the volunteers from the aripiprazole study. File 2. Prolactin pharmacokinetic parameters after aripiprazole and ibuprofen administration. This xls file shows the modifications in the prolactin concentrations after the administration of aripiprazole or ibuprofen A It is been shown the prolactin concentrations versus time in women and men treated with aripiprazole compared to ibuprofen File 3 Genotype Matrix. The xls file show the detected genetic polymorphism associated with the effects of aripiprazole File 4 Aripiprazole and dehydro-aripiprazole pharmacokinetic parameters. File 5 The influence of polymorphisms on prolactin concentrations., Aripiprazole treatment in schizophrenic patients was previously associated with lower or normalized prolactin levels. Genetic variants in cytochrome P450 (CYP) (CYP2D6), dopamine receptor (DRD2, DRD3) and serotonin receptor (HTR2A, HTR2C) genes were previously associated with antipsychotic-induced hyperprolactinaemia. Our aim was to evaluate whether aripiprazole affects prolactin secretion and its relationship with pharmacogenetics. Thirty-one healthy volunteers receiving a 10-mg single oral dose of aripiprazole were genotyped for 12 polymorphisms in CYP2D6, DRD2, DRD3, HTR2A and HTR2C genes by qPCR. Aripiprazole and dehydro-aripiprazole plasma concentrations were measured by HPLC-MS/MS. Prolactin concentrations of the 31 volunteers taking aripiprazole and 12 volunteers receiving ibuprofen were determined by ELISA. Prolactin concentrations after ibuprofen intake were considered as control, since it is known to cause no effect. Prolactin concentrations were slightly higher in the aripiprazole group compared to the ibuprofen group. All prolactin pharmacokinetic parameters were higher in females than in males. CYP2D6 poor and intermediate metabolizers had notably higher prolactin Cmax and AUC0-12 than normal and ultrarapid metabolizers. The DRD3 rs6280 polymorphism affected prolactin levels: volunteers carrying Ser/Ser genotype had significantly lower prolactin levels than volunteers carrying the Gly allele. Furthermore, HTR2C rs3813929 C/C homozygotes had significantly lower prolactin levels than T allele carriers. Nevertheless, aripiprazole did increase prolactin levels compared to ibuprofen., European Comission ITN Treatment H2020-MSCA-ITN-721236, Peer reviewed
