目的探讨中、小剂量利培酮治疗精神分裂症患者的血药浓度、临床疗效及不良反应。方法将82例精神分裂症患者随机分为口服利培酮剂量2mg/d组和4mg/d组。采用RP-HPLC和LC-MS方法测定利培酮(RSP)和9-羟利培酮(9-OH-RSP)之和的血浆浓度。用阳性和阴性症状量表(PANSS)评定临床疗效,用不良反应症状量表(TESS)评定不良反应。结果4mg/d组(RSP+9-OH-RSP)血浓度均显著高于2mg/d组。2mg/d组第1周末PANSS平均减分率<20%,其它各周末PANSS平均减分率>20%,而4mg/d组各周末PANSS平均减分率>20%.2mg/d组TESS评分明显低于4mg/d组。结论(RSP+9-OH-RSP)血浓度能较好地反映其临床效应。2mg/d和4mg/d利培酮治疗精神分裂症患者疗效相当,4mg/d利培酮治疗时起效更快,但易发生不良反应。
采用液相色谱—质谱联用技术测定60例精神分裂症患者利培酮(RSP)和9-羟利培酮(9-OH-RSP)之和的血浆浓度。用阳性和阴性症状量表(PANSS)评定临床疗效,用不良反应症状量表(TESS)评定副反应,对血药浓度与副反应进行相关分析。结果治疗后第8周末的PANSS总分与治疗前比较差异有统计学意义,血药浓度与副反应存在正相关。提示RSP+9-OH-RSP血药浓度与副反应密切相关,血药浓度的检测有助于预防副反应的发生。
AIM: To study the efficacy and side effects of both middle and low doses of risperidone in the treatment of first-episode schizophrenia, and to investigate the relationship between plasma concentration of RSP,9-OH-RSP and the efficacy or side effects occurred during RSP treatment. METHODS: Compared the patients treated with middle dosage of risperidone (groupB,40 cases)and the other 42 cases (groupA) that are treated with very low dosage of risperidone. RESULTS: Two groups were in statistical difference (P 0.05 ) by itself. But there were no significant difference between group A and group B (P 0.05 ). Group A took effect later than group B. Total scores of the treatment emergent symptom scale (TESS) were significantly lower in group A than in group B.The plasma concentration of 9-OH-RSP and the active moiety (RSP+9-OH-RSP) after one week's administration of risperidone were higher in group B than that in group A (P 0.05 ). CONCLUSION: This assay suggested that low dosage of risperidone is effective, safe and beneficial in the treatment of first-episode schizophrenia.
OBJECTIVE To evaluate the relationship between dose of risperidone and the steady plasma concentration of risperidone and 9-hydroxyrisperidone in schizophrenic patients.METHODS The steady plasma concentrations of risperidone and 9-hydroxyrisperidone were determined by HPLC-MS method and the relationship between total plasma concentration of risperidone and 9-hydroxyrisperidone and doses are evaluated.RESULTS The steady plasma concentration of RSP had a relationship with administered daily oral dose,r=0.766 8. A much better relationship existed between dialy dose of risperidone and the steady plasma concentration 9-hydroxyrisperidone (r=0.980 0) or the total active moiety,risperidone plus 9-hydroxyrisperidone concentrations(r=0.979 8).CONCLUSION The steady plasma concentrations of 9-hydroxyrisperidone or risperidone plus 9-hydroxyrisperidone were more related to the dialy dose of risperidone than that of risperidone. 9-hydroxyrisperidone has an important role in risperidone clinical application.
Objective To explore the relationship between serum concentration and clinical efficacy of quetiapine in the treatment of patients with schizophrenia. Methods The subjects were 70 inpatients with Positive and Negative Symptom Scale (PANSS) score of at least 60 before treatment. They were treated with quetiapine for 8 weeks, with the dosage range of 250 mg to 600 mg daily. The clinical efficacy and side effects were assessed with the PANSS and Treatment Emergent Symptom Scale before and at the 1st, 2nd, 4th and 8th weekend of treatment. The blood samples were gotten at the 1st, 2nd, 4th and 8th weekend of treatment, and the serum concentration of quetiapine was determined with high performance liquid chroma-tography. Results The serum concentration had significant positive correlation with the dose of quetiapine (r = 0. 248-0. 347 , P 0. 05-0. 01) . The responsive rate in patients with serum concentration of over 250 μg/L was 75%. The serum concentration in responsive patients was (320 ± 142) μg/L, significant higher than that in non-responsive patients (251± 109)μg/L The serum concentration was positively correlated to the reduction of PANSS score (r = 0. 343 - 0. 499, P0. 05-0.01). The lowest mean effective dosage was 344 mg per day. Conclusion Quetiapine is effective for schizophrenia and the clinical efficacy is related to its serum concentration. The lowest appropriate serum concentration of quetiapine is 250 μg/L It is of significance for monitoring serum concentration of quetiapine in treatment of schizophrenia.
OBJECTIVE To establish a RP-HPLC method for the determination of quetiapine fumarate concentration in patients with schizophrenia,and to study the relationship between serum concentration and clinical response. METHODS A HPLC method was used to determine quetiapine fumarate concentration.Blood samples were collected in 76 schizophrenia inpatients before or at the end of 2,4,6 weeks of quetiapine fumarate treatment and the therapeutic efficacy was measured by BPRS.RESULTS The standard curve was linear over the range of 50~500 ng.mL~-1 of quetiapine fumarate in serum (r=0.985 0).

OBJECTIV: To simultaneously determine the concentrations of risperidone and its main active metabolite 9-hydroxyrisperidone in serum of 16 psychotic patients. METHODS:Hypersil ODS-C 18 colunm was used as the stationary phase and a solution composed of methanol-water-triethylamine (73:36.5 :0.5,v/v, was adjusted to pH 8 with glacial acetic acid ) as the mobile phase with a flow rate of 1 .0 ml·min-1. The detection was performed at UV 280mm. RESULTS: The standard curve was linear within the concentration range of 10-100μg.L-1 of risperidone and 9-hydroxyrisperidone in serum (r=0.9950 and 0.9935). The recoveries of risperidone and 9-hydroxyrisperidone was between 98.3% to 102. 1%.The relative standard deviations for the within-day and the between-days variation were 6.71 %. The risperidone and 9-hydroxyrisperidone serum concentrations of 16 psychotic patients were in the range of 10.9-38.8μg.L-1 and 11 .5-49.7 μg.L-1 respectively within the dose of 2-5mg a day. CONCLUSION: The assay method is simple, precise and usable for therapeutic risperidone monitoring and its pharmacokinetic studies.
