Amisulpride withdrawal akathisia responding to aripiprazole with propranolol in first-onset psychosis: a case report

Comparative analysis of third-generation antipsychotics in first-episode schizophrenia: efficacy, safety, and cognitive impacts. A narrative review

BACKGROUND AND OBJECTIVES

Schizophrenia is a chronic, complex mental health disorder requiring effective management to mitigate its broad personal and societal impacts. This narrative review assesses the efficacy, effectiveness, and side effects of third-generation antipsychotics (TGAs) like aripiprazole, brexpiprazole, and cariprazine, focusing on their use in first-episode schizophrenia. These drugs aim to reduce side effects typical of earlier antipsychotics while more effectively addressing positive and cognitive symptoms.

METHODS

Our extensive literature review, using PubMed and Scopus , includes randomized controlled trials and observational studies, showing TGAs may match older antipsychotics in efficacy with fewer side effects, notably in reducing extrapyramidal symptoms and enhancing cognitive outcomes.

RESULTS

Aripiprazole appears effective in both acute and maintenance phases of schizophrenia, while brexpiprazole and cariprazine show potential in managing negative symptoms and improving social functioning, essential for patient recovery.

CONCLUSIONS

This review emphasizes the need for personalized treatment and further research to fully determine the long-term benefits and safety of TGAs. These findings can inform clinical decisions and underline the ongoing need for innovation in schizophrenia pharmacotherapy.

Strategies and Management for Psychiatric Drug Withdrawal: A Systematic Review of Case Reports and Series

In recent years, an increasing number of case reports on psychiatric drug withdrawal have emerged, offering detailed clinical insights and valuable real-world evidence on the withdrawal process. The objective of this review was to evaluate the strategies and management for withdrawing psychiatric drugs, as detailed in case reports and series. A systematic review of case reports and series published between 2013 and 2023 was conducted to capture the latest trends in psychiatric drug withdrawal. Cases were identified following the PRISMA guidelines by searching electronic databases Medline and Scopus. Finally, 47 case reports and series were included. The primary reason for drug withdrawal was attributed to the emergence of adverse events, followed by medication dependence or abuse, and clinical decision-making or symptom resolution. Gradual reduction of doses was implemented through various management approaches as the primary strategy for drug withdrawal, and drug substitution emerged as the second most employed strategy. Also, patients were mostly undergoing polypharmacy. Favorable treatment outcomes were reported in the majority of cases, suggesting that psychiatric drug withdrawal is feasible - though quite challenging in some situations. However, the remarkably low number of unsuccessful cases may create a misleading impression of the significant difficulty associated with withdrawing psychiatric drugs.
