PG - 750-755 LID - S0165-1781(16)30947-7 [pii] LID - 10.1016/j.psychres.2016.10.053 [doi] AB - This meta-analysis of randomized controlled trials (RCTs) investigated the advantages of long-acting injectable antipsychotics (LAI-APs) over oral antipsychotics (OAPs) with regard to efficacy and safety for patients with recent-onset psychotic disorders. Effect sizes and 95% confidence intervals (95%CIs) were calculated. We identified five RCTs (1022 patients, mean study duration=18+/-7.59 months) that compared LAI-APs (paliperidone or risperidone) with OAPs. Pooled LAI-APs did not outperform OAPs in terms of the preventing of relapse (N=3, n=875). However, there was significant heterogeneity (I(2)=76%), with one study showing no superiority of LAI-APs over OAPs [Malla 2013: risk ratio (RR)=1.83, 95%CI=0.70-4.77, n=77] and the other two studies showing LAI-APs to be superior [Schreiner 2015: [RR=0.71, 95%CI=0.51-0.97, number needed to treat (NNT)=-17, n=715, Subotnik 2015: RR=0.15, 95%CI=0.04-0.63, NNT=-4, n=83]. Pooling the studies, there were no significant differences between LAI-APs and OAPs in the improvement of Positive and Negative Syndrome Scale scores or in discontinuation due to all-cause, adverse events (AEs), and death, but LAI-APs outperformed OAPs in terms of discontinuation due to inefficacy (RR=0.34, NNT=-50) and nonadherence (RR=0.30, NNT=-33). However, the LAI-APs were associated with a higher incidence of at least one AE (RR=1.13) and tremor (RR=2.38) compared with OAPs. CI - Copyright (c) 2016 Elsevier Ireland Ltd. All rights reserved.
