Abbreviations:5 However, benefit was limited to antipsychotics and tricyclic antidepressants. When only studies that excluded individuals with co-existent mood disorder were considered, there was no benefit. Total numbers of adverse events and adverse events leading to withdrawal were significantly more common, with a number needed to harm of 21 for both.
Conclusion:Psychotropic drugs may be an effective treatment for FD, but the effect appears to be limited to antipsychotics and tricyclic antidepressants with fewer trials for other agents, meaning that firm conclusions for efficacy cannot be made. More data from high quality RCTs are required to support their use in the treatment of FD.Ford et al.
of 48What is already known about this subject?Functional dyspepsia (FD) is common and difficult to treat.Helicobacter pylori eradication therapy and proton pump inhibitors are efficacious treatments for FD, but the benefits are modest.Estimates of the efficacy of psychotropic drugs in FD have been hampered by a paucity of randomised controlled trials (RCTs), and a failure to report extractable dichotomous data.
What are the new findings?We identified 13 RCTs, and successfully contacted original investigators to obtain supplementary dichotomous data.Psychotropic drugs were more effective than placebo for the treatment of FD, with a number needed to treat of 6 (95% confidence interval (CI) 4 to 16).However, this beneficial effect was limited to antipsychotic drugs, such as sulpiride and levosulpiride, and tricyclic antidepressants (TCADs), such as amitriptyline and imipramine.Adverse events were more common (number needed to harm 21 (95% CI 9 to 597)).How might it impact on clinical practice in the near future?
