Pipotiazine

Pipotiazine (Piportil), also known as pipothiazine, is a typical antipsychotic of the phenothiazine class[1] used in the United Kingdom and other countries for the treatment of schizophrenia.[2] Its properties are similar to those of chlorpromazine. A 2004 systematic review investigated its efficacy for people with schizophrenia:

Pipotiazine palmitate compared to oral antipsychotics for schizophrenia[3]

Summary
Although well-conducted and reported randomized trials are still needed to fully inform practice (no trial data exists reporting hospital and services outcomes, quality of life, satisfaction with care and economics) pipotiazine palmitate is a viable choice for both clinician and person with schizophrenia.[3]
Outcome Findings in words Findings in numbers Quality of evidence Global outcomes No important clinical response Follow-up: by 3 week) There is no clear difference between people given pipotiazine palmitate and those receiving oral antipsychotics. These findings are based on data of low quality. RR 2.57 (0.76 to 8.63) Low Leaving the study early Follow-up: up to 5 weeks Pipotiazine palmitate may increase the chance of leaving the study early but the difference between people given pipotiazine palmitate and those receiving oral antipsychotics is not clear. These findings are based on data of low quality. RR 3.85 (0.46 to 32.22) Low Mental state Relapse Follow-up: by 18 months) Pipotiazine palmitate has not more - or less - effect on risk of relapse than oral antipsychotics. These findings are based on data of low quality. RR 1.55 (0.76 to 3.18) Low Adverse effects Tardive dyskinesia Oral antipsychotic drugs and pipotiazine palmitate carry similar risks of this problematic movement disorder. These findings are based on data of low quality. RR 1.03 (0.22 to 4.92) Low Dystonia Pipotiazine palmitate may slightly reduce the chance of experiencing this movement disorder but there is no clear difference between people given pipotiazine palmitate and those receiving oral antipsychotics. These findings are based on data of low quality. RR 0.32 (0.04 to 2.89) Low
