Input: The review currently includes seven randomised trials and 1567 participants that compared fluphenazine with low-potency antipsychotic drugs. The size of the included studies was between 40 and 438 participants. Overall, sequence generation, allocation procedures and blinding were poorly reported. Fluphenazine was not significantly different from low-potency antipsychotic drugs in terms of response to treatment (fluphenazine 55%, low-potency drug 55%, 2 RCTs, n = 105, RR 1.06 CI 0.75 to 1.50, moderate quality evidence). There was also no significant difference in acceptability of treatment with equivocal numbers of participants leaving the studies early due to any reason (fluphenazine 36%, low-potency antipsychotics 36%, 6 RCTs, n = 1532, RR 1.00 CI 0.88 to 1.14, moderate quality evidence). There was no significant difference between fluphenazine and low-potency antipsychotics for numbers experiencing at least one adverse effect (fluphenazine 70%, low-potency antipsychotics 88%, 1 RCT, n = 65, RR 0.79 CI 0.58 to 1.07, moderate quality evidence). However, at least one movement disorder occurred significantly more frequently in the fluphenazine group (fluphenazine 15%, low-potency antipsychotics 10%, 3 RCTs, n = 971, RR 2.11 CI 1.41 to 3.15, low quality of evidence). In contrast, low-potency antipsychotics produced significantly more sedation (fluphenazine 20%, low-potency antipsychotics 64%, 1 RCT, n = 65, RR 0.31 CI 0.13 to 0.77, high quality evidence). No data were available for the outcomes of death and quality of life. The results of the primary outcome were robust in a number of subgroup and sensitivity analyses. Adverse effects such as akathisia (fluphenazine 15%, low-potency antipsychotics 6%, 5 RCTs, n = 1209, RR 2.28 CI 1.58 to 3.28); dystonia (fluphenazine 5%, low-potency antipsychotics 2%, 4 RCTs, n = 1309, RR 2.66 CI 1.25 to 5.64); loss of associated movement (fluphenazine 20%, low-potency antipsychotics 2%, 1 RCT, n = 338, RR 11.15 CI 3.95 to 31.47); rigor (fluphenazine 27%, low-potency antipsychotics 12%, 2 RCTs, n = 403, RR 2.18 CI 1.20 to 3.97); and tremor (fluphenazine 15%, low-potency antipsychotics 6%, 2 RCTs, n = 403, RR 2.53 CI 1.37 to 4.68) occurred significantly more frequently in the fluphenazine group. For other adverse effects such as dizziness (fluphenazine 8%, low-potency antipsychotics 17%, 4 RCTs, n = 1051, RR 0.49 CI 0.32 to 0.73); drowsiness (fluphenazine 18%, low-potency antipsychotics 25%, 3 RCTs, n = 986, RR 0.67 CI 0.53 to 0.86); dry mouth (fluphenazine 11%, low-potency antipsychotics 18%, 4 RCTs, n = 1051, RR 0.63 CI 0.45 to 0.89); nausea (fluphenazine 4%, low-potency antipsychotics 15%, 3 RCTs, n = 986, RR 0.25 CI 0.14 to 0.45); and vomiting (fluphenazine 3%, low-potency antipsychotics 8%, 3 RCTs, n = 986, RR 0.36 CI 0.18 to 0.72) results favoured fluphenazine with significantly more events occurring in the low-potency antipsychotic group for these outcomes. The results do not show a clear difference in efficacy between fluphenazine and low-potency antipsychotics. The number of included studies was low and their quality moderate. Therefore, further studies would be needed to draw firm conclusions about the relative effects of fluphenazine and low-potency antipsychotics.
Output:

This review examined the effects of the high-potency antipsychotic fluphenazine compared with those of low-potency antipsychotics. A search for randomised trials comparing these types of drugs was carried out in 2010. The review includes seven studies with 1567 participants. Pooled data from two of these trials did not show a clear difference in effectiveness between fluphenazine and low-potency antipsychotics. However, evidence showed fluphenazine produced more movement disorders than low-potency antipsychotics, whereas the low-potency drugs were more likely to cause dizziness, drowsiness and sedation, a dry mouth, nausea and sometimes even vomiting. The number of included studies was low and the quality of evidence provided was moderate. Therefore, further good quality studies would be needed to draw firm conclusions about the relative effectiveness of fluphenazine compared to low-potency antipsychotics. Important information on service use, going into hospital again (rehospitalisation), costs and quality of life was missing and not reported.
