Post-traumatic stress disorder is a disabling condition resulting from a range of traumas and affecting many people worldwide. This month’s Cochrane Corner review systematically searched and reported findings from 66 randomised controlled trials of pharmacotherapy for PTSD, 54 of which were included in a meta-analysis. Evidence was shown for the benefit of selective serotonin reuptake inhibitors, mirtazapine and amitriptyline in treatment response. This Round the Corner commentary critically appraises the review’s findings, concluding that the summative evidence was of poor quality owing to the low number of studies, the high risk of bias and significant heterogeneity.
