nan Seventeen patients with acute schizophrenia and 30 with chronic schizophrenia were included in a randomized, double-blind parallel-group trial comparing sulpiride and perphenazine. Patients were evaluated using the 16-item Brief Psychiatric Rating Scale (BPRS) prior to the onset of treatment and 1 and 2 weeks, and 1, 2, 3, and 4 months thereafter. In patients with acute schizophrenia, total BPRS scores declined significantly at the end of the trial compared with pretreatment values in sulpiride-treated patients but not in schizophrenics treated with perphenazine. Differences in response between the groups did not reach statistical significance, however. For patients suffering from chronic schizophrenia, a statistically significant decline was observed in total BPRS scores at 4 months compared with pretreatment scores in both sulpiride and perphenazine groups. There was no significant difference in the treatment response between the groups. Sulpiride appeared to be somewhat more effective than perphenazine for treatment of acute schizophrenia. Efficacy of both compounds was less marked in chronic forms of schizophrenia. The efficacy of timiperone in schizophrenia as compared with perphenazine was assessed in a double-blind fashion in 205 patients throughout a 12-week treatment period. More than half of the subjects were chronic schizophrenics. Global improvement in the timiperone treatment group was superior to that in the perphenazine group in view of a lower rate of aggravation. With regard to overall safety and general usefulness rating, there were no significant differences between the two drug treatments. However, timiperone showed less frequency of excitability, irritability, anxiety and anorexia than perphenazine on occasions during the 12 week treatment period. From these results it may be concluded that the efficacy of timiperone could be superior or equivalent to that of perphenazine which has been confirmed to be of use as an antipsychotic. Studies of the efficacy of naltrexone for alcohol dependence have yielded variable findings, which may be due, in part, to variation in compliance with oral naltrexone. Efforts to improve naltrexone compliance have included the development of injectable, long-acting depot formulations.
                We conducted a multicenter trial in 315 subjects who were randomly assigned to receive an intramuscular injection of a depot formulation containing naltrexone (n = 158) or a placebo formulation (n = 157) monthly for 3 months. All patients received five sessions of manual-guided motivational enhancement therapy during the 12 weeks of the study. The outcomes of interest were based on self-reported alcohol use and gamma-glutamyl transpeptidase level. Missing data or data from subjects who discontinued the study were conservatively treated as heavy-drinking days.
                Groups were comparable on pretreatment demographic and clinical measures. The medication was well tolerated; 73.7% of subjects received all injections. The time to the first heavy-drinking day, the percentage of subjects with no heavy drinking throughout the study, and gamma-glutamyl transpeptidase levels favored the naltrexone depot, although the effects did not reach statistical significance. There was a significant advantage for naltrexone depot treatment on the time to the first drinking day. Naltrexone depot subjects also had significantly fewer drinking days during treatment and a significantly greater abstinence rate than the placebo group (18% vs. 10%).
                This is the first multicenter study of a depot formulation of naltrexone for the treatment of alcohol dependence. Using a conservative intent-to-treat analysis, the study showed an advantage for the active medication. Further research with this formulation is warranted. A double-blind, randomized, multicentre trial was carried out in 47 psychotic patients to evaluate the efficacy of oral treatment with loxapine compared with perphenazine. In total, 22 patients were included in diagnostic Group I (cases of acute schizophrenia and psychogenic (reactive) psychoses). The average maximum daily dose was 60.0 mg in the loxapine group and 36.8 mg in the perphenazine group. After 3-weeks' treatment, no significant differences were found between the two treatment groups according to the Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression (CGI) Scale or side-effect records. Twenty-five patients were included in diagnostic Group II (cases of chronic schizophrenia). The average daily dosage was 81.1 mg in the loxapine group and 90.1 mg in the perphenazine group. After 10 to 12-weeks' treatment, no significant differences between the two treatment groups could be found according to BPRS, CGI scale, Nurses' Observation Scale for In-patient Evaluation (NOSIE) or side-effect records. The diastolic blood pressure (lying and standing) tended to increase slightly in both treatment groups. In conclusion, it was found that loxapine and perphenazine seemed to be equally effective and, based on experience with parenteral loxapine treatment, it is suggested that further investigation of oral loxapine should be carried out in psychotic patients in whom agitation is a feature. The combination of antidepressants and neuroleptics has been widely recommended and commonly used clinically for the schizophrenic patient who becomes depressed. However, the value of the combination for these patients has not been clearly demonstrated. This report presents results of a double-blind, randomized, placebo-controlled clinical trial designed to evaluate the combination of perphenazine and amitriptyline hydrochloride with that of perphenazine alone in the treatment of 35 ambulatory chronic schizophrenic patients in whom depressive symptoms developed. Results showed that the addition of amitriptyline to perphenazine, when compared with perphenazine alone, was more effective in reducing symptoms of depression after four months of treatment, but less effective in reducing thought disorder. The study concludes that the value of adding an antidepressant to the usual neuroleptic in the treatment of secondary depression in schizophrenia should be reviewed. Most studies comparing second generation antipsychotics with classical neuroleptics have been conducted in more or less chronic schizophrenia patients. Such studies were usually conducted in highly selected samples, and were generally designed and financed by the manufacturer of the drug tested. These and other facts have stimulated discussions regarding the effectiveness of the new generation of antipsychotics.
                The aim of the European First Episode Schizophrenia Trial (EUFEST) is to compare treatment with amisulpride, quetiapine, olanzapine and ziprasidone to a low dose of haloperidol in an unselected sample of first episode schizophrenia patients with minimal prior exposure to antipsychotics.
                500 patients between the ages of 18-40 meeting DSM-IV criteria for schizophrenia, schizoaffective disorder or schizophreniform disorder are randomly allocated to one year of treatment with one of the drugs under study. The primary outcome measure is retention in treatment, defined as time to discontinuation of study drug. Loss of retention can be the result of insufficient clinical effect, or lack of tolerability or acceptance. Secondary measures include changes in different dimensions of psychopathology, side effects, compliance, social needs, quality of life, substance abuse and cognitive functions.
                At present, more than 400 patients have been recruited and randomized in the following countries: Austria, Belgium, Bulgaria, Czech Republic, Germany, France, Israel, Italy, the Netherlands, Poland, Rumania, Spain, Sweden and Switzerland: The study should be finished by the end of 2006 and it is expected that results will yield relevant clinical information with regard to the effectiveness of the second generation antipsychotics. This effort represents the first independently designed trans-European schizophrenia treatment trial. Fifty-four patients with acute psychotic states were included in a double-blind multicentre study of zuclopenthixol and perphenazine given orally. Fourteen patients had not received test preparations for a minimum of 3 weeks as stated in the protocol, and were excluded. The remaining 40 patients received the test preparations for 3 to 12 weeks, with an average of 49 days for patients receiving zuclopenthixol and 45 days for patients receiving perphenazine. Clinical evaluations were done at baseline and at weeks 1, 2, 4, 6, 8, and 12 including the CGI, a CPRS subscale for schizophrenia, and the UKU Side Effects Rating Scale. The patients received on average 37 mg zuclopenthixol or 30 mg perphenazine daily. Statistically, significant reductions on the CGI, severity of illness, and on the CPRS (total score) were found for both drugs when comparing baseline with later scores. No significant differences between the drugs were found. It was also impossible to demonstrate a difference in clinical profile between the two drugs on the basis of the single items on the CPRS. Although small differences between the two drugs were found, as regards number and type of side effects, it is concluded that the pattern of side effects was almost identical in the two treatment groups. On 30 women suffering from uterine fibroids, the monthly subcutaneous administration of goserelin depot (3.6 mg) for 6 (n = 22) or 12 months (n = 8) induced an about 50% shrinkage of uterus and fibroid volume, and within 3 months, an increase in the haematocrit value, with no metabolic side effects or detectable bone demineralization, evaluated by single photon absortiometry at distal radius. Both uterine and fibroid volumes reversed to pretreatment values after 3 months of goserelin depot withdrawal. In comparison with untreated subjects, on another 10 patients a three month administration of goserelin depot reduced the loss of blood during the surgical removal of the uterus or fibroids. Present data indicate that goserelin depot is effective and relatively safe in the medical management of uterine fibroids. Although, goserelin depot cannot yet be proposed as a definite medical therapy, it may represent a useful instrument in the presurgical management of uterine fibroids. nan We conducted a prospective, randomised, double-blind trial to study the effect of Synacthen Depot in 18 parturients with postdural puncture headache following deliberate or accidental dural puncture. Women were randomly allocated to receive either Synacthen Depot 1 mg (1 ml) or 0.9% saline 1 ml intramuscularly. Using a 10-cm visual analogue scale, severity of headache was measured before and at intervals until 48 h after injection. There was no difference in the severity of headache or requirement for epidural blood patch. We conclude that there is no advantage to the use of Synacthen Depot 1 mg for the treatment of postdural puncture headache.
Depot perphenazine is in clinical use in the Nordic countries, Belgium, Portugal and the Netherlands. At a conservative estimate, a quarter of a million people suffer from schizophrenia in those countries and could be treated with depot perphenazine. The total number of participants in the four trials with useful data is 313. None of the studies observed the effects of oral versus depot antipsychotic drugs. Until well conducted and reported randomised trials are undertaken clinicians will be in doubt as to the effects of perphenazine depots and people with schizophrenia should exercise their own judgement or ask to be randomised.
