Selected AbstractsAmisulpride: a review of its efficacyin schizophreniaACTA PSYCHIATRICA SCANDINAVICA, Issue 400 2000H. J. Möller Objective: To assess the efficacy of the new atypical antipsychotic drug, amisulpride. Method: Studies comparing the efficacy of amisulpride with that of haloperidol and risperidone, respectively, are reviewed. Outcome measures were Clinical Global Impression, Brief Psychiatric Rating Scale (BPRS), and Positive And Negative Symptom Scale (PANSS) scores. Results: Amisulpride was at least as effective as haloperidol and risperidone in the improvement of positive symptoms, and significantly more efficacious than haloperidol in reducing PANSS negative subscores (P=0.038) in patients with acute exacerbations. Amisulpride demonstrated a greater improvement in BPRS total scores (P<0.05) and PANSS negative subscores (P=0.0001) than haloperidol after 12 months of treatment in chronic schizophrenic patients with acute exacerbations. Conclusion: Amisulpride can thus be considered for use as first-line treatment of acute and chronic schizophrenia.

Methods A randomized, double-blind, placebo-controlled, multi-center clinical trial was conducted. All 200 patients who met the DSM-IV diagnostic criteria for schizophrenia were randomly assigned to double-blind treatment with WSKY capsule (n,=,100) or placebo (n,=,100) added on risperidone for 8 weeks. The primary outcome measure was the cognitive function assessment assessed by the classic form of the Wisconsin Card Sorting Test (WCST) at baseline and week 8. The secondary outcome measures were assessed including the positive and negative symptoms scale (PANSS), the social disability screening schedule (SDSS), and the Hamilton rating scale for depression (HAM-D-17) at baseline, week 2, week 4, and week 8. The extrapyramidal side effects were assessed each week using the abnormal involuntary movement scale (AIMS) and rating scale for extrapyramidal side effects (RSESE), while adverse events were assessed using treatment emergent symptoms scale (TESS) as additional indicators of tolerability throughout the trial. Results The response rates of the WSKY group for the number of completed categories (CC), errors responses number (ER), perseveringly errors responses number (PER), and conceptual level (CL) of WCST assessment were significantly higher than those of placebo. The reduction in the SDSS score from baseline to endpoint was significantly greater in the WSKY group than those in the placebo. There were no significant differences in the response rates for the correct responses number, perseveringly responses number (PR) of WCST between the treatment groups. The improvements in the WCST indexes, PANSS score, HAM-D-17 score were no significant differences from baseline to endpoint between the two groups at week 8.There were no significant differences in AIMS, RSESE, and TESS compared patients treated with WSKY capsule with those in placebo during treatment. Conclusion WSKY capsule added on risperidone may improve cognitive function, social function of the chronic schizophrenic patients, and the WSKY safely during treatment.

[source] Effect of antipsychotic replacement with quetiapine on the symptoms and quality of life of schizophrenic patients with extrapyramidal symptomsHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 7 2006Takahide Taniguchi Abstract Replacement of antipsychotic drugs with quetiapine (QTP) was tried in a naturalistic setting in chronic schizophrenic patients who still showed moderate psychiatric symptoms and either showed extrapyramidal symptoms (EPS) or took anti-parkinson drugs for the EPS. QTP was added on and gradually increased while the previous drugs were tapered and discontinued whenever possible. Clinical symptoms, objective and subjective QOL, and EPS were measured before and 6 months after QTP addition, using Brief Psychiatric Rating Scale (BPRS), Quality of Life Scale (QLS), Schizophrenia Quality of Life Scale (SQLS) and Drug-Induced Extrapyramidal Symptom Scale (DIEPSS), respectively. Twenty-one patients completed the trial and received the assessment. It was found that replacement with QTP-improved clinical symptoms, objective and subjective QOL and EPS. This improvement was equally observed in not only patients who switched to QTP monotherapy (n,=,11) but also patients who took QTP together with reduced small doses (4.4,±,4.3,mg/day) of previous drugs (n,=,11). The results suggest that replacement with QTP improves symptoms as well as objective and subjective QOL in a subgroup of schizophrenia. Copyright © 2006 John Wiley & Sons, Ltd. [source] Plasma serotonin response to carbohydrate-rich food in chronic schizophrenic patients: clozapine versus classic antipsychotic agentsHUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue 5 2001Yaffa Vered Abstract Researchers have reported a stimulatory effect of carbohydrate-rich intake on platelet-poor plasma (PPP) serotonin (5-HT) levels in healthy human subjects. Dietary manipulation may serve as a safer and less invasive means than pharmacologic challenge to provoke serotonergic responsivity in studies of schizophrenia. In the present study, we used the carbohydrate-rich meal test as an indicator of 5-HT activity in 12 patients with chronic schizophrenia maintained for at least 6 months on clozapine. PPP 5-HT levels were measured at baseline and at 1, 2 and 3,h after administration of the test. Findings were compared with those in schizophrenic patients treated with classic antipsychotic agents for the same duration. The maximal PPP 5-HT response was reached 120 min after meal administration in the clozapine-treated group and 60 min after in the classic antipsychotic-treated group (P<0.05 vs baseline for both). The 5-HT level (as percentage of baseline) at 60 min was significantly lower in the clozapine-treated group (P<0.02), as were individual PPP 5-HT peak values (P<0.05). The individual time to reach the peak response was similar in the two groups. Our results indicate that in patients with chronic schizophrenia 5-HT responsivity to the natural challenge of carbohydrate-rich meals is lower in those treated with clozapine than in those given classic antipsychotic agents. Values in both groups were lower than those in an appropriate historical comparative group of healthy subjects. We suggest that both clozapine and classic antipsychotic agents suppress serotonergic system sensitivity, but to a different degree. Copyright © 2001 John Wiley & Sons, Ltd. [source] | ||||||||||
