Risperidone long-acting injectable was found to be effective in protecting from any mood/manic symptom compared to placebo , but not from depressive recurrences .
Add-on or monotherapy paliperidone palmitate in SAD patients  protected from psychotic , depressive , and manic symptoms .
In patients with BD-I with a manic episode at study enrolment , aripiprazole monohydrate significantly delayed time to recurrence of manic episodes without inducing depressive episodes .
LAIs  are effective and well-tolerated maintenance treatments for BD and SAD .
They showed better efficacy in preventing mania than depression .
LAIs may be first-line for BD-I and SAD patients with a manic predominant polarity and with non-adherence problems
Long-Acting Injectable Antipsychotics ( LAIs ) are used to overcome non-compliance in psychoses , mainly schizophrenia spectrum disorders .
We aim ed to summarize available evidence of studies comparing the efficacy of LAIs to placebo or oral medications for Bipolar Disorder ( BD ) and /or Schizoaffective Disorder ( SAD ) .
Head-to-head comparison of 1-year aripiprazole long-acting injectable (LAI) versus paliperidone LAI in comorbid psychosis and substance use disorder: impact on clinical status, substance craving, and quality of life
Background To overcome nonadherence in patients with psychosis switch to long-acting injectable ( LAI ) antipsychotic formulations is adopted . Most oral versus LAI comparisons showed similar antipsychotic responses . Psychoses often overlap with substance use disorder ( SUD ) . Head-to-head LAI comparisons have hitherto focused only on non-comorbid population s. Objective The objective of this study was to compare two LAIs , administered for 12 months , in initially hospitalized patients with psychosis comorbid with SUD in their clinical and quality of life ( QoL ) outcomes . Patients and methods In patients were recruited during 2016 and switched r and omly to 400 mg intramuscular aripiprazole monohydrate ( AM ) ( N=50 ) or to 100 mg intramuscular paliperidone palmitate ( PP ) once-monthly ( N=51 ) ; patients were discharged and followed up for 12 months . Patients were rated at baseline and after 1 year through the Clinical Global Impression scale – severity ( CGIs ) , substance craving intensity was rated through a visual analog scale for substance craving , and QoL through the World Health Organization ( WHOQOL-BREF ) scale . We addressed confounders with backward stepwise logistic regression and three-way analysis of variance . Results PP were older and had more cases of schizophrenia spectrum and less bipolar disorders than AM , but AM had a stronger craving for substances at baseline . Both LAIs were associated with significant improvements in all outcomes , with AM displaying stronger effect sizes than PP . The two groups did not differ on baseline WHOQOL-BREF scores in any domain , but at the 1-year follow-up , AM fared better on all domains . The two groups did not differ in final severity , but PP scored higher than AM in craving at the 1-year endpoint . Limitation : The CGIs is not a refined tool for severity and the substance craving may be subject to recall bias . Conclusion 1-year AM and PP was followed by improved clinical status and QoL and reduced substance craving in a population with psychosis and SUD comorbidity . AM , compared to PP , improved craving and QoL at the 1-year follow-up
