Abstract
Introduction
Therapeutic Drug Monitoring (TDM) of antipsychotics in schizophrenia is a powerful tool that allows tailoring the treatment in an individualized approach. Our goals are to develop and validate a Dried Blood Spot (DBS) method for monitoring some commonly used antipsychotics (aripiprazole, clozapine, and paliperidone) and to evaluate its usefulness as a compliance biomarker, as well as in drug-dose adjustment to personalize the antipsychotic treatment to improve its efficacy and safety.
Methods
31 first-psychotic episode (FEP) and schizophrenia patients were included; 5 refer to naïve FEP who started antipsychotic treatment; 26, to patients with more than one episode and under antipsychotic treatment: aripiprazole (7 cases), clozapine (17), paliperidone (11). For DBS sample collection, 25 μl of capillary blood were placed in the spot of a FTA™DMPK-C-card. After completely dryness, antipsychotics were extracted and analyzed by a validated UHPLC-MS/MS-method. DBS antipsychotic results were compared with those obtained in venous blood/plasma.
Results
Aripiprazole, paliperidone and clozapine showed from good to excellent correlations between concentrations in venous blood and DBS capillary blood (r2, from 0.500 to 0.721). The correlation between conventional plasma and DBS concentrations for paliperidone, aripiprazole, clozapine, and their metabolites were moderate, suggesting that optimal drug target concentrations should be established for DBS.
Conclusions
In this study, for aripiprazole, dehydroaripiprazole, paliperidone, clozapine and desmethylclozapine, DBS has provided good analytical performance for TDM. Thus, DBS sampling can offer a great alternative over conventional sampling for plasma measurement. The assay provides good analytical performances for TDM and clinical research applicability, suggesting that DBS is a promising clinical application in TDM in psychiatry.
期刊介绍：
The Spanish Journal of Psychiatry and Mental Health (SJPMH), incorporated into ISSN 1888-9891, is the official scientific publication of the Spanish Society of Psychiatry and Mental Health. The journal focuses on studying mental illnesses, their pathological processes, and their psychosocial consequences, and aims to disseminate scientific advances in all areas related to mental health and illness. SJPMH accepts unpublished works on psychiatry and mental health, including their medical and social implications. The journal provides space for research in the biological, clinical, and psychosocial fields. Manuscripts undergo peer-review by external reviewers before being accepted for publication. SJPMH is indexed in Index Medicus/Medline, IBECS, Social Sciences Citation Index Journal Citation Reports/Social Sciences Edition, and Current Contents/Social and Behavioral Sciences.
