AbstractBipolar disorder is a complex mental illness. Pharmacological therapy, including antipsychotics and mood stabilizers, is the primary treatment approach for manic episode. The study aimed to analyze prescribing patterns over a 14-year period for patients with bipolar mania discharged from a psychiatric hospital in Taiwan. Patients with bipolar mania discharged from the study hospital between 2006 and 2019 (n = 2956) were included in the analysis. Prescribed drugs for the treatment of manic episode, included mood stabilizers (i.e., lithium, valproate, carbamazepine) and any antipsychotics (i.e., second- and first-generation antipsychotics; SGAs & FGAs). Monotherapy, simple polypharmacy, and complex polypharmacy were also examined. Simple polypharmacy was defined as being prescribed 2 different bipolar drugs (lithium, valproate, carbamazepine, and any antipsychotics), while complex polypharmacy at least 3 bipolar drugs. Temporal trends of each prescribing pattern were analyzed using the Cochran-Armitage Trend test. The prescription rates of valproate, SGAs, and complex polypharmacy significantly increased over time, whereas the prescription rates of any mood stabilizers, FGAs, and simple polypharmacy significantly decreased. Prescription rates of lithium and monotherapy did not significantly change. The study highlights the shifts in prescribing practices for bipolar mania. SGAs were prescribed more while FGAs declined, likely due to SGAs' favorable properties. Complex polypharmacy increased, reflecting the complexity of treating bipolar disorder. Long-term outcomes of these changes require further research.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
