Abstract
The primary aim of the present study was to assess the possible associations between dopaminergic, serotonergic, and glutamatergic system-related genes and adverse events after antipsychotic treatment in paranoid schizophrenia patients. The second aim of the study was to compare the intensity of these symptoms between atypical (ziprasidone and olanzapine) and typical (perazine) antipsychotic drugs. One-hundred and ninety-one Polish patients suffering from paranoid schizophrenia were genotyped for polymorphisms of DRD2, DAT1, COMT, MAOA, SERT, 5HT2A, and GRIK3. The patients were randomized to treatment with perazine, olanzapine or ziprasidone monotherapy for 3 months. The intensity of side effects (changes in body weights and extrapyramidal symptoms (EPS)) was measured at baseline and after 12 weeks of antipsychotic treatment. After 3 months of therapy, the weight increase was the greatest in the group treated with olanzapine and the least in the group treated with ziprasidone. None of the examined gene polymorphisms was associated with the body weight changes. Perazine treatment was associated with the significantly highest intensity of EPS. None of the examined polymorphisms was associated with the changes in extrapyramidal adverse events after antipsychotic treatment. The selected polymorphisms are not primarily involved in changes in body weights and EPS related to antipsychotic treatment in paranoid schizophrenia patients.

Abstract
BACKGROUND Perazine is an old phenothiazine derivative used for the treatment of people with schizophrenia and is reputed to have a low level of extrapyramidal adverse effects. As far as we are aware, its use is limited to Germany, Poland, the former Yugoslavia and the Netherlands. OBJECTIVES To examine the effects of perazine for those with schizophrenia or related psychoses in comparison with placebo, no treatment or other antipsychotic medications. SEARCH METHODS We searched the Cochrane Schizophrenia Group Trials Register, which includes relevant randomised controlled trials from the bibliographic databases Biological Abstracts, CINAHL, The Cochrane Library, EMBASE, MEDLINE, PsycLIT, LILACS, PSYNDEX, Sociological Abstracts and Sociofile. We searched the references of all included studies for further trials. We contacted pharmaceutical companies and authors of trials. We updated this search on 16th July 2012. SELECTION CRITERIA We selected all randomised controlled trials that compared perazine with other treatments for people with schizophrenia or schizophrenia-like psychoses, or both. DATA COLLECTION AND ANALYSIS The review authors (SL, BH, BHe) independently inspected the citations and where possible abstracts and ordered papers for re-inspection and quality assessment. We independently extracted data. We calculated the risk ratio (RR) and 95% confidence interval (CI) using a random-effects model. For continuous data, we calculated mean differences (MD). We inspected all data for heterogeneity, assessed trials for risk of bias and created summary of findings tables using GRADE. MAIN RESULTS The review now includes seven trials with a total of 479 participants. In only one trial, with 95 participants, perazine appeared superior to 'active placebo' (trimipramine) at five weeks for the outcome of 'no important global improvement' (n = 95, RR 0.43 CI 0.2 to 0.8, low quality evidence), but there was no statistically significant difference in most measures of mental state. Perazine did not induce more general adverse events than placebo but more participants received at least one dose of antiparkinson medication (n = 95, RR 4.50 CI 1.0 to 19.5, very low quality evidence).Six small trials comparing perazine with other antipsychotics, including 384 participants in total, were incompletely reported and the outcomes were presented in various ways so that meta-analysis was not possible on most occasions. In the six studies, a similar number of participants receiving perazine or comparator antipsychotics (amisulpride, haloperidol, olanzapine, ziprasidone, zotepine) left the studies early (n = 384, RR 0.97 CI 0.68 to 1.38, low quality evidence). The results on efficacy could not be meta-analysed because the authors presented their results in very different ways. No obvious differences in adverse events between perazine and other antipsychotics could be derived from the limited data. Two haloperidol comparisons did not present extrapyramidal side-effects in a way that was suitable for use in meta-analysis, but three small comparisons with the second-generation antipsychotics zotepine and amisulpride showed no higher risk of akathisia (n = 111, RR 0.31 CI 0.1 to 1.1), dyskinesia (n = 111, RR 0.47 CI 0.1 to 3.5), parkinsonism (n = 81, RR 1.21 CI 0.5 2.8) or tremor (n = 40, RR 0.80 CI 0.3 to 2.6) with perazine. AUTHORS' CONCLUSIONS The number, size and reporting of randomised controlled perazine trials are insufficient to present firm conclusions about the properties of this antipsychotic. It is possible that perazine is associated with a similar risk of extrapyramidal side-effects as some atypical antipsychotics but this is based on small comparisons. This should be clarified in larger, well-designed trials.

Abstract
AIM The aim of the present study was twofold: 1. to compare the efficacy of three antipsychotics (ziprasidone, olanzapine and perazine) in schizophrenia 2. to compare the improvement in cognitive functioning between groups treated with the three different neuroleptics. METHOD A total of 58 Caucasian patients diagnosed with paranoid schizophrenia were recruited into the study group. We used the Polish version of the CIDI (Composite International Diagnostic Interview) to obtain ICD-10 diagnoses. The intensity of psychopathological symptoms was examined using the PANSS. The patients were randomly assigned to treatment with perazine, olanzapine or ziprasidone administered as monotherapy for 3 months. The treatment efficacy was measured as a change in the PANSS (Positive and Negative Syndrome Scale) total score from baseline (T0) to 3 months (T1). The WCST (The Wisconsin Card Sorting Test) was used to measure working memory and executive functions in the evaluated patients. Wilcoxon's and Kruskal-Wallis tests were applied to compare changes in the PANSS scores between the treatment groups. To analyze the cognitive functions, Kruskal-Wallis test for the WCST parameters was used. RESULTS The three antipsychotics similarly reduced the total PANSS score. The WCST parameters in the 3 groups of examined patients using the Kruskal-Wallis test revealed some differences between the three administered antipsychotics. CONCLUSIONS Results suggest that the short-term efficacy of the atypical (olanzapine, ziprasidone) and typical (perazine) antipsychotic drugs did not differ. Based on the analysis, a conclusion can be drawn that the three neuroleptics provided similar improvements in cognitive functioning.

Abstract
AIM Currently, the use of first generation antipsychotics (FGA) is strongly limited. On the other hand, treatment with second generation antipsychotics (SGA) can not be applied in every patient. Therefore, there is an urgent necessity to obtain information about the knowledge and experience of clinicians with regard to safety and efficacy of pernazine, which represents the most widely used FGA in Poland. Due to a striking scarcity of studies on pernazine, authors designed and performed the study, which should provide physicians knowledge arising from daily practice of clinicians included in this study. METHODS Analysis was performed basing on 142 opinions of 26 physicians who were experienced in the treatment with pernazine. The Delphi method, which relies on concluding from expert opinions was adopted in this study. A three-round Delphi was used in order to yield final conclusions. RESULTS According to clinicians, pernazine is one of the most cost-effective and well-tolerated FGA. Furthermore, its different profiles of action (anxiolytic and sedative) enable to use pernazine in various indications, as well as in polypharmacotherapy. Referring to a long-term experience, clinicians emphasised the efficacy of pernazine and a high compliance with medication. CONCLUSIONS Psychiatric treatment should be individualised taking into account not only clinical indices but also patient's preferences and expectations. According to clinicians pernazine is a safe and versatile medication for schizophrenia or other mental disorders and serves as the alternative for SGA.

Abstract
The author reviewed the relatively poor literature on the topic and its key clinical trial reports on perazine, a classical antipsychotic most frequently prescribed in Poland for psychoses, especially for schizophrenia. Based mainly on the Leucht and Hartung's metaanalysis as well as on other authors' trials with broader context of typical and atypical neuroleptics comparisons, it could be concluded that the perazine bearing balanced profile of psychotropic action (antipsychotic, anti-autistic and sedative) has also some atypical features which explain its broad applications in clinical practice. Not without a meaning are also a few dozen-fold lower costs of treatment, which are even more meaningful when costs of necessary laboratory tests required for monitoring atypical antipsychotics use are taken into consideration.

Abstract
Malignant neuroleptic syndrome (MNS) is a serious and potentially fatal side-effect of neuroleptic treatment. Beside antipsychotic drugs, other psychotropic drugs such as antidepressants and lithium carbonate can cause this life threatening side-effect. Underlying mechanism of this side-effect is still unknown and debated. So far some risk factors have been identified, with clinical observations and recent pharmacogenetic research suggesting (with inconsistent findings) correlation between genetic mechanisms and predisposition to MNS. Polymorphisms of CYP2D6 enzyme through which most psychotropic drugs are metabolized and TaqIA DRD2 which is target for antipsychotic drugs could be the link between pharmacogenetic factors and potential for development of MNS. In this paper we present two case reports with clinical presentation of three consecutive MNS. One patient developed MNS while he was taking combination of drugs: first time haloperidol, promazine and fluphenazine, second time fluphenazine and perazine and third time clozapine, promazine and valproic acid consecutively. The other patient developed MNS while taking following combination of drugs: first time haloperidol and lithium carbonate, second time risperidone and third time clozapine consecutively. Pharmacogenetic analysis for CYP2D6 and TaqI A DRD2 polymorphisms for both patients was done. Genotypisation of CYP2D6*1*3*4*5*6 in both patients showed no evidence of poor metabolizer phenotype. On the other hand, first patient was heterozygous for CYP2D6*4 (genotype *1/*4). CYP2D6 polymorphisms could have clinical significance because may lead to toxicity and unwanted side-effects in standard usual antipsychotic dose ranges. Analysis Taql A DRD2 polymorphism for first patient showed that he is heterozygous for A1 allele (genotype A1A2) which is commonly associated with predisposition to MNS. According to our literature three consecutive MNS are rarely described, and incidence of MNS generally is too low to perform clinical research. Many patophysiological mechanisms may probably underlie this complex and potentially fatal syndrome, still unknown etiology. But, genetic mechanisms could be significant. Further pharmacogenetic research, findings and analysis in patients who develop single or repeated MNS are strongly recommended. In long term, pharmacogenetic analysis, implemented in daily clinical practice, could help in prevention of this extremely serious side-effect.

Abstract
Atypical antipsychotics like olanzapine are more efficacious in treating negative symptoms and have less side effects. Nevertheless, important adverse effects of olanzapine are, for example, weight gain and hyperglycemia. Perazine in combination with carbamazepine has shown satisfying results in several single-schizophrenia patients, leading to the hypothesis of being equal or even superior to atypical antipsychotic monotherapy. The aim of the present study was to survey the hypothesis that perazine in combination with carbamazepine have an outcome and risk of side effects comparable to olanzapine. Eleven patients with DSM-IV schizophrenia received 14.0 +/- 5.0 mg/day olanzapine and 12 patients received 360.0 +/- 196.0 mg/day perazine in combination with 404.0 +/- 229.0 mg/day carbamazepine. Symptoms and neuropsychological state were assessed 3 times (days 0, 7, 21) using the Positive and Negative Syndrome Scale and the Brief Psychiatric Rating Scale. The neuropsychological state was assessed by the following neuropsychological tests: Benton, d2, ZVT, VLMT and MWT-B. Data were analyzed of variance for multiple dependent variables and repeated-measures multivariate analysis of variance. Positive and Negative Syndrome Scale and Brief Psychiatric Rating Scale scores showed superior improvement in the group receiving olanzapine. Olanzapine offers a more favorable response in positive symptoms than does perazine in combination with carbamazepine. The effect on negative symptoms is favorable in both forms of therapy and no significant differences between the groups could be determined. In both groups, treatment was associated with improved performance in cognitive tests; however, no differences were determined in the effects of the drugs. Results suggest that olanzapine offers a better response in positive symptoms than perazine in combination with carbamazepine.

Abstract
An automated HPLC method with column switching is described for the determination of quetiapine, clozapine, perazine, olanzapine and metabolites in blood serum. After clean-up on silica C8 material (20 microm particle size) drugs were separated on ODS Hypersil C18 material (5 microm; column size 250 mm x 4.6 mm i.d.) within 25 min and quantified by ultraviolet (UV) detection at 254 nm. The limit of quantification ranged between 10 and 50 ng/ml. At therapeutic concentrations of the drugs, the inter-assay reproducibility was below 10%. Analyses of drug concentrations in serum of 75-295 patients treated with therapeutic doses of the antipsychotic drugs revealed mean+/-S.D. steady state concentrations of 139+/-136 ng/ml for quetiapine, 328+/-195 ng/ml for clozapine, 48+/-27 ng/ml for olanzapine and 71+/-52 ng/ml for perazine. The method was thus suitable for routine therapeutic drug monitoring and may be extended to other drugs.

Abstract
BACKGROUND Reversible schizophrenia-like syndromes have been reported to occur with small-cell carcinoma of the lung, thymoma, and hematological disorders. CASE REPORT A 56-year-old man was admitted due to an acute psychosis characterized by delusions, agitation, and aggressive outbursts. His medical and psychiatric history was unremarkable. On treatment with olanzapine, valproic acid, and perazine there was only moderate improvement. Extensive checkup revealed an isolated mediastinal metastasis of an undifferentiated carcinoma. A primary tumor was not found. After removal of the metastasis, the psychosis remitted rapidly and completely, and the patient remained well on follow-up. CONCLUSIONS Paraneoplastic syndromes may clinically present as acute psychoses and, in late-onset schizophreniform disorders with an atypical presentation, performing a tumor search should always be considered.

Abstract
BACKGROUND The tricyclic antidepressant trimipramine exhibits several features (e. g., dopaminergic effect, molecular structure similar to a neuroleptic, receptor-binding profile similar to clozapine) that suggest its potential as an antipsychotic medication. The aim of the study was to investigate the antipsychotic potential of trimipramine in a controlled clinical trial comparing its antipsychotic efficacy with that of a neuroleptic. METHOD In a German multi-center, randomized, double-blind trial, the antipsychotic efficacy of trimipramine was compared with that of the phenothiazine neuroleptic perazine, using the Brief Psychiatric Rating Scale (BPRS), the Positive and Negative Syndrome Scale (PANSS), and Clinical Global Impressions (CGI). Antidepressant efficacy of both agents was measured by use of the Bech-Rafaelsen Melancholia Scale (BRMES). Ninety-five patients with acute schizophrenia (DSM-III-R) and a BPRS total score > 40 at baseline were treated with either 300-400 mg trimipramine or 450-600 mg perazine for 5 weeks. RESULTS Therapeutic equivalence of both treatments (in the dosages used) could not be demonstrated (change in BPRS total score, per-protocol [PP] analysis, one-sided equivalence testing). However, intention-to-treat (ITT) as well as PP analysis showed a statistically significant decrease in the BPRS total scores in both treatment groups (PP: trimipramine, 56.5 +/- 9.8 to 44.1 +/- 17.9; perazine, 56.4 +/- 10.8 to 37.9 +/- 12.9). Significant decreases in all BPRS and PANSS subscores as well as CGI results and response rate support the antipsychotic efficacy of trimipramine. The BRMES total scores significantly decreased in both treatment groups without showing a significant difference between the two agents. Trimipramine was better tolerated than perazine and did not elicit extrapyramidal symptoms. CONCLUSION Trimipramine failed to exhibit therapeutic equivalence to perazine in the dosages used. However, there was evidence of a substantial antipsychotic effect of trimipramine. It may be a useful medication if depressive symptoms in psychotic patients require antidepressant treatment or if other antipsychotics cannot be administered.

Abstract
BACKGROUND Perazine is an old phenothiazine derivative used for the treatment of people with schizophrenia which has a reputed low level of extrapyramidal side-effects. However, its use is restricted in the sense that - to the best knowledge of the reviewers - it is only marketed in Germany, Poland, Yugoslavia and the Netherlands. OBJECTIVES To examine the effects of perazine for those with schizophrenia, and schizophrenia-like psychoses. SEARCH STRATEGY Electronic searches of the Cochrane Schizophrenia Group's register which includes relevant randomised controlled trials from the bibliographic databases Biological Abstracts, CINAHL, The Cochrane Library, EMBASE, MEDLINE, PsycLIT, LILACS, PSYNDEX, Sociological Abstracts and Sociofile were undertaken. References of all included studies were searched for further trials. Pharmaceutical companies and authors of trials were contacted. SELECTION CRITERIA All randomised controlled trials that compared perazine with other treatments for people with schizophrenia and/or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS Citations and, where possible, abstracts were independently inspected by two reviewers, papers ordered, re-inspected and quality assessed. Data were independently extracted. Data were excluded if loss to follow up was greater than 50%. For homogeneous dichotomous data the Relative Risk (RR), 95% confidence interval (CI) and, where appropriate, the number needed to treat (NNT) were calculated on an intention-to-treat basis. For continuous data, weighted mean differences were calculated (WMD). All data were inspected for heterogeneity. MAIN RESULTS Six trials with a total of 288 participants are included. According to only one trial with 95 participants perazine appeared superior to active placebo (trimipramine) at five weeks for the outcome of 'no important global improvement' (n=95, RR 0.6, CI 0.3-0.9, NNT 4, CI 2-17), but there was no difference in various measures of mental state. The side-effect risk of perazine compared to placebo could not be estimated because they were not reported. Five small trials including only 193 participants which compared perazine with other antipsychotics were incompletely reported and the outcomes were presented in various ways so that meta-analysis was not possible in most occasions. A similar number of participants receiving perazine or comparator antipsychotics left the studies early (n=193, RR 0.9, CI 0.5-1.4). The results on efficacy were controversial and need further assessment by randomised controlled trials. No obvious differences in adverse events between perazine and other antipsychotics could be derived from these limited data. Two haloperidol comparisons did not present extrapyramidal side-effects in a way usable for meta-analysis, but three small comparisons with the atypical antipsychotics zotepine and amisulpride showed no higher risk of akathisia (n=111, RR 0.3, CI 0.1-1.1), dyskinesia (n=111, RR 0.5, CI 0.1-3.5), parkinsonism (n=81, RR 1.2, CI 0.5-2.8) or tremor (n=40, RR 0.8, CI 0.3-2.3) with perazine. REVIEWER'S CONCLUSIONS The number, size and reporting of randomised controlled perazine trials is insufficient to present firm conclusions about the properties of this antipsychotic. It is possible that perazine is associated with a similar risk of extrapyramidal side-effects as some atypical antipsychotics, and this should be clarified in larger, well-designed trials.

Abstract
We have reported the case of a 65-year-old woman treated with neuroleptics because of organic delusive disturbances. She was treated for about one month with risperidone (Rispolept) and perazine (Pernazinum). Around ten days before the patient was admitted to this ward, the following had been observed: rise in temperature up to 40 degrees C, progressive weakness and blood pressure (RR) fluctuationis. Despite the applied treatment, the patient died during the fourth of hospitalization on this ward. The diagnosis of neuroleptic malignant syndrome was made on the basis of the clinical picture accomplished whole of biochemical, figurative tests as well as on the conducted differential diagnostics.

Abstract
Some recent reports show that schizophrenia is accompanied by changes in lymphocyte activity. This study investigated the activity of monocytes by determining their release of interleukin- 1 beta (IL- 1 beta) and tumor necrosis factor-alpha (TNF-alpha). Monocytes were immunomagnetically isolated from the peripheral blood of schizophrenic patients before and after neuroleptic medication and stimulated by lipopolisaccharide (LPS) in vitro. The monocytes of schizophrenic patients released significantly higher amounts of IL- 1 beta and TNF-alpha than those of healthy controls. Treatment with the typical neuroleptics haloperidol and perazine decreased the release of IL- 1 beta and TNF-alpha to the control levels. The study has shown that the activity of monocytes is increased in schizophrenia and that neuroleptic treatment normalizes this activity.

Abstract
Data on liver enzyme elevations were collected in a retrospective study of 7,263 treatment courses with haloperidol, clozapine, perphenazine, and perazine. Charts of 233 patients hospitalized between 1980 and 1992 at Tübingen University Psychiatric Clinic were selected because clinically relevant increases of liver enzymes had been detected during monotherapy with one of the four examined neuroleptics. At least one hepatic enzyme (mostly alanine aminotransferase [ALAT]) exceeded the established reference range of 3-fold elevations of ALAT, aspartate aminotransferase, gamma-glutamyl transpeptidase, and glutamate dehydrogenase and 2-fold elevations of alkaline phosphatase (AP) during monotherapy with clozapine in 15%, perazine in 7.6%, perphenazine in 4%, and haloperidol in 2.4% of the cases. If all liver enzyme abnormalities with any elevation greater than the conventional upper limits are considered, incidences were as follows: clozapine, 78%; perphenazine, 62%; perazine, 59%; and haloperidol, 50%. Testing for overall differences within the four neuroleptics resulted in significantly different incidences of liver enzyme elevations (chi2 test,p < 0.0001). Threefold increases of AP (>540 U/L) were seen in three patients receiving haloperidol (0.3%) only. Twofold increases of AP (>360 U/L) were distributed as follows: clozapine, 1%; haloperidol, 0.8%; perazine, 0.3%; and perphenazine, 0.1%. Only in the group with 1-fold elevations of AP (>180 U/L) were the differences within the drug regimens significant (clozapine, 40.3%; haloperidol, 33.2%; perphenazine, 23.4%; and perazine, 23.1%; chi2 test, p < 0.0001). In the period under study, no instance of icterus occurred.

Abstract
An intoxication following an apparent overdose of clozapine (Leponex) and perazine (Taxilan) is reported. There was a wide range of variation in postmortem blood and tissue concentrations of clozapine, desmethyclozapine and perazine. Clozapine/norclozapine blood and tissue ratios and perazine-pill-fragments in the gastric content could be used as a sign of suspected acute clozapine and perazine overdose.

Abstract
A reduced P300 amplitude has often been found to be related to schizophrenic psychopathology. It is still unclear, however, whether this relationship is trait- or state-dependent. We investigated 88 stabilized schizophrenic outpatients during a 2-year follow-up period. Multivariate analyses revealed that patients who had reduced P300 amplitudes showed pronounced residual symptoms, especially thought disorder (Brief Psychiatric Rating Scale). Intraindividual changes in that psychopathology were not correlated to corresponding changes of the P300 amplitude, so the relationship between schizophrenic psychopathology and P300 amplitude appears to be, at least in part, trait-dependent. A reduced P300 amplitude may characterize a subgroup of schizophrenic patients with a disposition to cognitive disturbances and incomplete remissions.

Abstract
This article aims at drawing attention to the peculiar association of intense exposure to sunlight and subacute development of sensory neuropathy which was seen in 7 psychiatric patients treated with the phenothiazine derivative, perazine. Three patients additionally developed bilateral VII nerve palsy. Symptoms followed a monophasic course with almost complete remission. Routine neurophysiology suggested axonal neuropathy confirmed by sural nerve biopsy in 1 patient. A toxic origin of neuropathy is supposed, possibly induced by phenothiazine photoproducts, which may cause cell damage via lipid peroxidation.

Abstract
Perazin is a piperazine derivative of phenothiazine with higher affinity for the D2 than the D1 receptor. We observed a 43-year-old woman who developed blepharospasm and oral hyperkinesia as a tardive dystonic syndrome after short-term treatment with perazin. She had never taken any other neuroleptic medication and all known forms of secondary dystonia were ruled out. We were unable to find any previous reports of perazin-induced tardive dystonia.

Abstract
Schizophrenics with a neurodevelopmental disturbance resulting in micro- and macroanatomical cortical abnormalities are supposed to form a subgroup clinically characterized by low premorbid adjustment, early onset, incomplete remission, poor outcome, male predominance and high risk for tardive dyskinesia. A small amplitude of the event-related P3 (P300) potential could be a marker of this subgroup, because the cortical neurons and their orderly laminar arrangement are crucial for the electrogenesis of P3. In a 2-year follow-up study, auditory evoked P3 was recorded in 89 stabilized schizophrenic outpatients. Patients who developed tardive dyskinesia during the follow-up had smaller P3 than matched controls. Furthermore, a small P3 was associated with low premorbid adjustment, pronounced residual symptoms, low relapse rate, and male predominance. These findings indicate that schizophrenic patients with a reduced P3 have a higher risk of developing tardive dyskinesia and correspond clinically to a schizophrenic subgroup with a supposedly neurodevelopmental disturbance.

Abstract
Cycloid psychoses have a special position in psychiatric classification. Usually they are listed among atypical psychoses, located between the group of schizophrenias and affective psychoses. Nevertheless, there are indications for nosological differentiation of cycloid psychoses from other psychotic conditions. The case of cycloid psychosis of a 38 year old woman with two severe psychotic episodes of mixed, paranoid and affective symptomatology is described. Among the characteristic features of psychotic episodes were acute onset, severe but short course of the episodes and the lack of residual/defect symptoms at outcome. On the basis of this case the differential diagnosis of cycloid psychoses is discussed.

Abstract
Cardiovascular measurements were used as indicators of autonomic arousal during an orthostatic challenge test without medication and after a test dose of 150 mg perazine in 20 acute schizophrenic patients. Unmedicated schizophrenics showed elevated heart rates and elevated systolic and diastolic blood pressure in comparison to healthy volunteers. After a test dose of 150 mg perazine, responders (using BPRS outcome criteria after 23 days) showed a pronounced orthostatic heart rate reaction in comparison to nonresponders. Results are discussed in relation to arousal theories and central dopaminergic activity in schizophrenia.

Abstract
Several investigators have found that the initial improvement of acute schizophrenia after some days of neuroleptic treatment is correlated in a statistically significant way to the outcome after four weeks. In all these studies the question arises as to whether the correlation between early response and subsequent outcome is due to a specific response to a certain neuroleptic, or whether patients who respond early simply have a better prognosis. In order to isolate the specific drug effect from prognostic influences we performed a controlled double-blind study in 50 newly admitted schizophrenic inpatients. All patients were treated over three days with 15 mg haloperidol i.v., following which they were classified as 'early responders (ER)' (markedly improved or improved) or as 'early nonresponders (EN)' and then randomly assigned to group 1 (3 x 5 mg haloperidol p.o./d) or to group 2 (3 x 100 mg perazin p.o./d). If there was a specific drug effect on the correlation between early response and subsequent outcome a therapeutic superiority of perazin in EN and no superiority in ER was expected. Independently of the treatment condition the mean BPRS score had decreased from 61.2 (Sx = 12.1) to 38.1 (Sx = 13.9) at the end of the study. ER and EN were evenly distributed in the haloperidol and perazin group. The analysis of variance revealed no significant interactions of the factors 'treatment condition' x 'duration' x 'early response' (p = 0.27) and 'treatment condition' x 'early response' (p = 0.88) on the outcome (BPRS, CGI). This means that the initial hypothesis of this study has to be rejected.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Total fatty acids were analysed in thrombocytes of schizophrenic patients treated with a "high dose" or "low dose" monotherapy of neuroleptic drugs phenothiazine or thioxanthene. The ratio of the very long chain fatty acid hexacosanoic acid to the long chain fatty acid docosanoic acid (C26:0/C22:0) increased in the "high dose" and "low dose" groups as compared to healthy untreated controls (P less than 0.05). The polyunsaturated fatty acid arachidonic acid decreased in the "high" and "low dose" groups (P less than 0.01 and P less than 0.05). The polyunsaturated fatty acids alpha-linolenic acid, eicosapentaenoic acid and docosahexaenoic acid were not detectable in most of the "high dose" schizophrenic patients, however, they were found in the "low dose" group and in the controls. There was a negative correlation between the daily dosage of phenothiazine and the percentages of the polyunsaturated fatty acids arachidonic acid and alpha-linolenic acid+eicosapentaenoic acid+docosahexaenoic acid in thrombocytes (r = -0.87, P less than 0.01 and r = -0.81, P less than 0.01). Two patients of the "high dose" group with an especially high and long lasting monotherapy of neuroleptics were nearly devoid of polyunsaturated fatty acids in their thrombocytes. Untreated schizophrenic patients exhibited a fatty acid pattern in their thrombocytes not markedly different from that of the healthy untreated control group. We conclude that neuroleptic drugs phenothiazine or thioxanthene can alter the fatty acid pattern of thrombocytes.

Abstract
Toxic epidermal necrolysis (Lyell syndrome) developed in a 43-year woman treated with carbamazepine, perazine, and sulpiride for recurrent manic bipolar disorder. Five days after withdrawal of all psychotropic medication her psychiatric illness was exacerbated and a syndrome of lethal catatonia developed which was promptly treated with unilateral electroconvulsive therapy (ECT). Rapid remission of lethal catatonia after the first ECT treatment and of her affective disorder within days was achieved. According to clinical observations of the preneuroleptic era, early improvement of lethal catatonia following ECT may have been supported by concurrent high dose corticosteroid therapy for toxic epidermal necrolysis.

Abstract
Thirty-six acute schizophrenics were included in a 28-day open treatment study with the neuroleptic perazine. Peak serum levels of parent drug and its main inactive metabolite desmethyl-perazine were assessed 2 hours after an oral test dose given at the beginning of the study. Whereas peak levels of perazine were not significantly different in treatment responders and nonresponders, desmethyl-perazine was significantly higher in nonresponders. The ratio between desmethyl-perazine and perazine was not predictive of (non-) response to neuroleptic treatment in schizophrenia.

Abstract
The clinical action of Zotepine was examined in an open and in a randomised double-blind controlled study in in-patients displaying a productive or minus pattern of symptoms within the framework of a schizophrenic disease or schizoaffective psychosis. The present paper discusses only the results achieved in treating schizophrenic minus patterns of signs and symptoms. In Study I 20 schizophrenic patients were treated with two different Zotepine dosages. Group 2 (n = 12) showed at an average daily dose of 168 +/- 15 mg (150-190 mg) a significant improvement (p less than 0.05) of the anergy subscore in the BPRS scale as well as a significant improvement of the subscores affective flattening, anhedonia/asociality and attentional imparvement in the SANS scale, compared with Group 1 (n = 8) with an average daily dose of 270 +/- 37 mg (240-340 mg). This improvement developed already during the first two weeks of the treatment. In Study II the antipsychotic action of Zotepine compared to that of perazine was studied under double-blind conditions. The average daily dose in the Zotepine group (n = 20) was around 241 +/- 70 mg (106-396 mg), in the perazin group (n = 19) at 348 +/- 09 mg (214-575 mg). With regard to the BPRS subscore anergy and all the subscores of the SANS scale, there was a distinct improvement without significant group differences. Both substances were comparably well tolerated.

Abstract
40 inpatients suffering from a schizophrenia (ICD-9) were treated with either zotepine or perazin. The study was continued for a period of 28 days. Assessment of clinical efficacy was effected via BPRS, AMDP, CGI and SANS; tolerance was assessed by means of Simpson's scale. In addition, EEG, ECG and laboratory controls were conducted. The overall therapeutic efficacy was good, and it was not possible to distinguish one group from the other, i.e. both substances were equally effective, judged by means of the psychopathometric tools that were at our disposal. In 11 patients of the zotepine group and in 9 patients of the perazin group, slight extrapyramidal symptoms were observed. No clinically relevant changes were seen in EEG, ECG and laboratory controls in both groups.

Abstract
The dibenzothiepine zotepine is a new potential "atypical" neuroleptic exhibiting powerful antiserotonergic and antidopaminergic properties. The efficacy of zotepine was evaluated in a double-blind controlled trial versus the tricyclic neuroleptic perazine in 41 patients suffering mainly from the paranoid-hallucinatory type of schizophrenia. The key outcome variable was the extent of mental disturbance as defined by the total score of the BPRS. Additional outcome variables were GAS and CGI. In addition, adverse reactions and extrapyramidal side effects were assessed according to the FSUCL scale and the Gerlach and AIMS rating scale, respectively. Additional variables recorded were blood pressure, heart rate and routine laboratory parameters as well as electrocardiogram and electroencephalogram. In the first two days, standard equivalent doses of both drugs were administered. Thereafter, doses were administered as required. The efficacy of both substances was compared after 7, 14 and 28 days of treatment. Both drugs showed a similar antipsychotic efficacy. Under zotepine treatment a 55% improvement of the BPRS total score was observed while perazine led to a 41% BPRS score reduction. After 7 days the zotepine group was significantly more improved than the perazine group, possibly due to a dosing effect in the perazine group. In the zotepine group, fewer adverse reactions and a better benefit/risk index were observed although the differences between the two treatment groups did not reach levels of statistical significance. There were no drug-specific abnormal laboratory findings. Thus, in the present study there was no significant difference between zotepine and perazine with respect to antipsychotic efficacy and side-effect rates. However, zotepine showed a trend to a better benefit/risk index at the end of treatment.

Abstract
In order to evaluate the influence of some neuroleptics on unproductive symptoms of schizophrenic process, first hospitalized patients with paranoid schizophrenia underwent monotherapy with perazine, fluphenazine, trifluoroperazine, chlorpromazine, and haloperidol. All the drugs eliminated the productive activity of the disease process within 2 months in both women and men aged 18-40 years. However, drugs showed different qualitative and quantitative effects on unproductive symptoms of schizophrenic process; this fact allows the suggestion regarding the particular usefulness of drugs in the out-patient care.

Abstract
As part of a follow-up study on long-term neuroleptic treatment, 36 schizophrenic out-patients under neuroleptic treatment were studied in an 'auditory oddball' event-related potential paradigm after a 3-month stabilization phase following clinical discharge. In the first cross-sectional analysis, we evaluated the influences of age and gender and tried to find auditory evoked potential (AEP) variables, which might be promising as potential predictors of the course of illness. Compared with healthy age-matched controls, the patients showed smaller N1/P3-amplitudes. Males and females showed only minor AEP-differences, the amplitude N1/P2 being slightly higher in females. Age correlated positively with the latency P3 and negatively with the latency P2R. The interpeak latency P3-P2R showed the highest correlation with age. Test/re-test reliability was measured and variables with r less than 0.60 were rejected. The amplitudes N1/P2 and N1/P3 showed the highest test/re-test correlations. The more severely disturbed patients (global assessment scale [GAS]-score less than 65) had shorter interpeak latencies P2F-N1F than the less disturbed patients (GAS greater than or equal to 65). Patients with a high rate of relapse tended to have shorter interpeak latencies P2F-N1F than patients with low rates of relapse. Our results indicate that the interpeak latency P2F-N1F has an acceptable test/re-test reliability (C3: r = 0.72; C4: r = 0.80) and is related to clinical variables characterizing the course and outcome of illness. This leads to the hypothesis that a short interpeak latency, P2F-N1F, might be a predictor of poor prognosis.

Abstract
This complication normally arises between the 5th and 10th weeks of treatment and is most commonly seen in middle-aged and elderly women. The risk is estimated to be between 0.04% and 2%, depending on the type of medication and the method of assessment. The present report describes a 16-year-old boy who developed agranulocytosis after 4 weeks of treatment with perazine. The problem was complicated by acute toxoplasmosis. After perazine was discontinued the neutrophils recovered within 5 days; the boy did develop fever, but the infectious disease had a mild course. This case report once again confirms the importance of regular blood control during the early phases of treatment with psychopharmacological agents.

Abstract
Skin conductance and heart rate of 19 drug-free acute schizophrenic patients were measured before neuroleptic therapy was started. The patients were divided into two groups according to therapeutic outcome. The Discriminant Analysis revealed a difference in the ANS activity pattern between the group with low improvement and the group with a more favorable outcome. The low improvement group showed a paradoxical ANS reactivity pattern: relatively lower activity in skin conductance level under demand (attention task) and relatively higher activity, as reflected by the cardiovascular response to neutral stimuli (orienting stimuli), which suggests poor adaptation of ANS arousal to the environment in these schizophrenics. This finding agrees with those reported in other short-term outcome studies that considered differences in ANS activity in a schizophrenic population. The authors' findings indicate that these differences in the ANS response in schizophrenics should be included in future biochemical and pharmacotherapeutic investigations on schizophrenia.

Abstract
The proportion of interview time spent in eye-contacts was studied before the onset of and during neuroleptic treatment in a group of 24 male schizophrenic patients. A significant increase in eye-contacts after 14 days distinguished responders to neuroleptic treatment, while a tendency towards the same effect distinguished patients treated with haloperidol from those treated with perazine. Only in the subgroup of responders was there a significant relationship between increase in eye-contacts and reduction of psychopathologic symptoms, regardless of whether these values were compared for the same treatment days or whether early changes in eye-contacts were compared with final outcome of treatment after 28 days. Since the patient subgroups were rather small, the results should still be considered preliminary. A prospective study including more parameters of visual interaction, a larger patient sample, and a longer observation period is required.

Abstract
Almost all adverse reactions to neuroleptic drugs in the gastro-intestinal system can be explained by their peripheral cholinergic blocking action with subsequent inhibition of intestinal tone and peristalsis. As a rare condition, severe diarrhoea due to enteritis may occur. A case with this complication is presented, the etiology and pathogenetic factors are discussed.

Abstract
A 22-year-old female patient developed agranulocytosis 26 days after starting single agent treatment with perazine. In accordance with the clinical and hematological picture this agranulocytosis is classified as antibody mediated with destruction of peripheral neutrophils. After cessation of perazine treatment and proper therapy of infection the patient recovered within two weeks. The diagnosis of agranulocytosis should be suspected in anyone on neuroleptic treatment who develops fever, malaise or objective evidence of an infection and in neutropenic patients the adequate treatment should be started immediately.

Abstract
Psychiatric drug treatment often means life-long therapy Controlled long-term drug trials in psychiatric patients over periods of more than three years, however, do not exist. Organisational and ethical reasons prohibit placebo controlled or even standard drug controlled trials over periods of one decade and more. The present paper illustrates the methodology and scientific significance of well-documented long-term follow-up studies by example of the structure and scientific results of two outpatient clinics: (1) a schizophrenic outpatient clinic taking care of approximately 200 patients of whom a subgroup has been treated with perazine for now 18 years on the average; (2) a lithium clinic taking care of approximately 100 actively participating patients.--It is suggested that this kind of "naturalistic" open trials, set up in accordance with conditions normally occurring in psychiatric practice, are a necessary complement to other controlled methodologes.

Abstract
In 23 acute, unmedicated, schizophrenic patients, psychotic behaviour and beta-endorphin serum level were measured before and during four weeks of neuroleptic therapy. Prior to drug treatment, beta-endorphin level of all patients was within the normal range. Neuroleptic therapy induced marked elevations of beta-endorphin in eight subjects; statistical analysis revealed a slight but significant increase for the whole group. This endocrine effect was not correlated with therapeutic efficacy of neuroleptic treatment.

Abstract
Twenty-eight patients with acute schizophrenic illness received an oral daily dose of 200-800 mg perazine (Taxilan) for 4 weeks. Weekly plasma level determinations showed a constant perazine concentration from day 7 to day 28, whereas the equilibrium level of its metabolite desmethyl perazine was only achieved at day 14; on an average it amounted to twice the level of perazine. Additional measurements were carried out 2 and 4 h after administration of the morning dose on day 14. The maximal increase of the perazine concentration was usually reached after 2 h; though it varied between 7 and 240% of the morning level, a close correlation existed between minimal and maximal levels. The perazine fraction not bound to plasma proteins was found to be 3.1-5.5% on day 21. The percent improvement in target syndromes during 4 weeks of neuroleptic therapy, as documented with the AMDP system, was most marked in those patients who had perazine levels in the 100-230 ng/ml range at day 28; patients with lower or higher levels improved significantly less. Curvilinear relationships also appeared to exist between improvement and free perazine concentration as well as maximal level on day 14. With regard to total scores on the Brief Psychiatric Rating Scale or scores of higher-order factors, no significant relationship between improvement and perazine level was found. The desmethyl perazine concentration did not exhibit a significant relationship to the therapeutic result. The pharmacokinetic parameters investigated seem to have a limited influence on the clinical outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In an open study of schizophrenic patients treated with perazine (Taxilan), a multidimensional approach comprising the following three areas was chosen: 1. psychopathology (AMDP, BPRS); 2. psychophysiology (habituation of skin resistance reaction, pulse rate); 3. pharmacokinetics (perazine-desmethylperazine plasma levels). Looking beyond the known global effect of the neuroleptic drug, interactions between these three areas were studied. Furthermore, methodological questions concerning possible predictor variables for treatment outcome were examined. Finally, an improved method for analyzing psychopathological data was employed. The methodological framework of the study, the examination techniques, and patient population are presented.

Abstract
In a pharmacopsychiatric pilot study 28 patients with an acute schizophrenic illness were treated for 4 weeks with perazine (Taxilan). Research goals in the psychopathological investigation were: (1) to assess the range of efficacy, target symptoms and syndromes of perazine and to compare these results with previous studies; (2) to compare the quality, interrater reliability, and practicability of two instruments of psychopathological assessment (AMDP and BPRS) for measuring change during treatment; (3) to apply new mathematical methods for finding statistically significant changes in symptomatology on the item level as well as on the levels of syndrome and total score; (4) to test whether pre-treatment prediction based on psychopathological evaluation or psychophysiological data is possible. The target symptoms and syndromes of perazine were the "positive" schizophrenic syndromes, above all thought disturbances and delusional phenomena. This result was consistent with a former perazine investigation. The BPRS proved to be a practicable and reliable instrument for a more global evaluation of change in psychopathology. The AMDP seemed to be especially useful for evaluating the homogeneity of a sample and showing differentiated psychopathological profiles. On this scale, changes in symptomatology became statistically apparent more clearly and more quickly on the syndrome level rather than on the level of single items. As to interrater reliability, both scales perform well. Dichotomizing the original scaling may mean a loss of information from both scales (AMDP and BPRS) in their evaluation of change. Hence it seems necessary to introduce new mathematical procedures (e.g., Friedman and Dunn-Rankin tests) into pharmacopsychiatric research.(ABSTRACT TRUNCATED AT 250 WORDS)
