A group of 28 patients was treated to compare the effects on akathisia of the following: propranolol (80 mg/day), benztropine (6 mg/day), or placebo. Both propranolol and benztropine significantly improved akathisia by Day 3-5 of treatment. Placebo had no significant effects of akathisia. Three patients developed confusion or forgetfulness by Day 3 of benztropine treatment; these effects cleared upon discontinuation of benztropine.

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

Department of Psychiatry, Chosun University Hospital, Gwangju, Republic of Korea.
Background: Akathisia tends to develop as an early complication of antipsychotic treatment in a dose-dependent manner. Although withdrawal akathisia has been reported after the discontinuation or dose reduction of typical antipsychotic drugs, akathisia following atypical antipsychotic drug withdrawal remains a rare phenomenon.
Case Presentation: A 24-year-old woman with an acute psychotic episode was admitted and initially treated with aripiprazole.
Effects of Paliperidone Palmitate on Healthcare Utilization and Costs for Patients with Schizophrenia: A Claim-based Mirror-image Study in South Korea.

Objective: Long-acting injectable (LAI) antipsychotics, such as paliperidone palmitate (PP), are known to improve treatment adherence in patients with schizophrenia, which can lead to reductions in relapse and hospitalization rates. However, relatively few studies have demonstrated the economic impact of LAIs, especially in Asian populations.
Methods: We conducted a claim-based mirror-image study to explore changes in healthcare utilization and associated costs, among 1,272 South Korean patients with schizophrenia (ICD-10-CM code F20), between the 1-year periods before and after the initiation of PP treatment.
Evaluation of postmortem redistribution phenomena for commonly encountered drugs.
Forensic Sci Int
June 2012
National Forensic Service, Yang-Chun Gu, Seoul, South Korea.
We described the findings of a study into the post-mortem redistribution (PMR) of 76 drugs found in 129 drug-related cases between 2006 and 2009. Seventy six drugs (psychotropic drugs (n=14), antidepressants (n=9), sedatives (n=6) and so on) were simultaneously quantified in cardiac and peripheral blood by gas chromatography-mass spectrometry (GC/MS) or liquid chromatography-tandem mass spectrometry (LC/MS/MS). The absence, possibility or presence of PMR of drugs was determined according to the ratios of cardiac to femoral blood concentrations (C/P ratios).

Objective: To document the effects of combining loxapine with aripiprazole for refractory hallucinations in 2 patients with chronic schizophrenia.
Case Summary: Two patients with schizophrenia and auditory hallucinations that were unresponsive to what was considered adequate treatment with multiple typical and atypical antipsychotic medications given over several years were prescribed a combination of aripiprazole 20-30 mg and high-dose loxapine (100-300 mg/day). Both patients had refused clozapine and depot antipsychotics.
