Abstract
Akathisia is a common and distressing extrapyramidal side-effect, which usually results from the use of antipsychotic medication. Previous reviews and meta-analyses have demonstrated a lack of evidence for the effectiveness of treatment strategies, which are traditionally used against neuroleptic-induced akathisia (NIA), i.e. beta-blockers, anticholinergic agents and benzodiazepines. In the last fifteen years, randomized trials have studied the effect of drugs with antiserotonergic properties on NIA. We conducted a systematic review of randomized control trials and used meta-analytic methods to quantify the overall effect size. PubMed and the Cochrane libraries were searched for eligible trials. Six randomized controlled trials were found, five of which included a placebo control group and qualified for our meta-analysis. The overall effect size in the analysis is RR = 7.10 with 95% CI 3.08-16.40 (p < 0.0001). Our findings suggest that 5-HT(2A) antagonists are effective in the treatment of NIA.
