Introduction: The management of pediatric bipolar disorder (PBD) requires pharmacotherapy to control acute symptoms, reduce relapse, prevent suicide, and improve psychosocial functioning. The purpose of this study was to investigate prescribing patterns among PBD patients discharged from two public mental hospitals in Taiwan, from 2006 to 2019.
Methods: PBD patients discharged from the two study hospitals, from 1 January 2006 to 31 December 2019 (n = 420), were included in the analysis. Prescribed drugs at discharge, including mood stabilizers (i.e., lithium, valproate, carbamazepine, and lamotrigine), antipsychotics (i.e., second- and first-generation antipsychotics, SGAs and FGAs), and antidepressants, were explored. Complex polypharmacy was defined as the use of 3 or more agents among the prescribed drugs. Time trends of each prescribing pattern were analyzed using the Cochran-Armitage Trend test.
Results: The most commonly prescribed psychotropic agents were SGAs (76.0%), followed by valproate (65.7%) and FGAs (24.8%). The prescription rates of SGAs, antidepressants, antidepressant plus antipsychotic, and antidepressant without mood stabilizer significantly increased over time, whereas the prescription rates of mood stabilizers, lithium, and FGAs significantly decreased.
Discussions: Prescribing patterns changed greatly for PBD patients over time. However, much more evidence supporting the effectiveness of psychotropic agents in PBD patients is required.
