Input: We include one RCT with relevant data on 29 participants in this review. The trial had a parallel design and was double-blind, but blinding procedures were not described. The trial included people who were non-responsive to fluphenazine 20 mg/day administered for 4 weeks. Participants were randomly assigned to continuing treatment with fluphenazine 20 mg/day, increasing the dose to fluphenazine 80 mg/day or switching to haloperidol 20 mg/day for four additional weeks. Data were reported only for 47 out of 58 initially randomised participants. The trial was published in 1993. The fact that only one RCT with a small sample size (N = 29) was included in the analysis limits the quality of the evidence. Overall, no clear difference was found between groups in terms of the three available outcomes: global state (number of participants with clinically relevant response (RR 1.63, 95% CI 0.17 to 15.99, very low quality evidence); general mental state (endpoint score, BPRS total) (MD 2.00, 95% CI −4.20 to 8.20, very low quality evidence); and negative symptoms (endpoint score, SANS) (MD 3.40, 95% CI −12.56 to 19.36). No data were reported for leaving the study early, adverse effects, time in hospital, quality of life, satisfaction with care and functioning. There is extremely limited evidence and no clear conclusions can be drawn. There is an urgent need for further trials in order to determine the optimal treatment strategy for people with schizophrenia who do not respond to their initial antipsychotic treatment.
Output:

The Information Specialist of Cochrane Schizophrenia ran an electronic search (up to 30 March 2017) for trials that randomised people with schizophrenia who were not responding to their initial antipsychotic treatment to receive either an increased antipsychotic dose or switch to a different antipsychotic drug. Nine hundred and two records were found and checked by the review authors. Only one trial met the review requirements and provided usable data. Data were reported for the number of participants who responded to treatment, the general mental state of participants at endpoint of the trial and the presence of negative symptoms at endpoint. There were no data available for any other outcome. No clear difference between increasing the dose of the antipsychotic drug and switching to a different antipsychotic was shown. The available evidence was extremely limited and of very low quality. The results of the present review show that there is no good-quality evidence to help clinicians decide between increasing the antipsychotic dose or switching to a different antipsychotic drug for people not responding to their initial antipsychotic treatment. Therefore, no clear conclusions can be drawn. Larger, well-designed trials are needed.
