ABSTRACT
OBJECTIVE:To investigate the characteristics of central nervous system(CNS)ADR caused by olanzapine,and to provide reference for safe and rational drug use in clinic. METHODS:Thirty cases of CNS ADR caused by olanzapine reported by our hospital to national ADR monitoring center were collected during 2004-2015. General information of patients,drug therapy, ADR,treatment measures and outcomes were analyzed statistically. RESULTS:Among 30 cases of CNS ADR caused by olanzapine, the female was more than male(22/8);the age of patients mainly ranged 21-40 years old(10 cases,33.3%). The original disease was given priority to schizophrenia (18 cases,60.0%). When ADR occurred,average dose of olanzapine was (18.0 ± 7.0) mg/d. The daily dose of 20 mg accounted for the most of ADR(8 cases,26.7%). Main ADR was extrapyramidal syndrome(22 cases, 73.3%). When mostly reduced the drug dose,stopped olanzapine,switched to other antipsychotics,and actively adopted symp-tomatic support treatment,the symptoms were relieved or returned to normal. CONCLUSIONS:The extrapyramidal syndrome take up the majority of CNS ADR caused by olanzapine. ADR is also likely to happen even if the daily dose is small. CNS ADR are more likely to happen in women. At the beginning of the treatment within a month,close attention should be paid to ADR. It is sug-gested to grasp the indications strictly and observe ADR so as to ensure the safety of drug use.
ABSTRACT
OBJECTIVE:To analyze the features of risperidone-induced leucocytopenia ADR.METHODS:Twenty-one ADR cases of risperidone-induced leucocytopenia reported by our hospital were collected and analyzed during 2004-2015.The characteris tics of risperidone-induced leucocytopenia were discussed.RESULTS:Among 21 patients,there were 10 male and 11 female.The age was from 15 to 72 years old.Nine cases of patients were 31-40 years old (42.9％).Most of the original disease was schizophre nia.Incubation period of leucocytopenia caused by risperidone was (28.6 ± 21.4) d.Patients had no discomfort complain when leucocytopenia occurred.The lowest white blood cells reported was(3.1 ± 0.5)× 109 L-1.The leucocytopenia were improved after reduc tion,drug withdrawal and symptomatic treatment.CONCLUSIONS:Patients usually have no body discomfort complain when risperidone-induced leucocytopenia appears.Doctors should moniter ADR regularly,identify it earlier and treat carefully.
ABSTRACT
OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.
ABSTRACT
0.05).There was a littel difference in the costs for an identical effect between two drugs,the cost of Risperidon being lower.CONCLUSION:The total effective rates and costs of Risperidon and Clozapine were almost equal in the treatment of schizophrenia.
ABSTRACT
OBJECTIVE:To investigate the clinical utilization and the tendency of antidepressant drugs in Beijing area.METHODS:Using the analytical method of the defined daily dose(DDD)recommended by WHO,the application of antidepressant drugs in Beijing from 2005 to 2007 was analyzed statistically.RESULTS:The consumptive sum and DDDs of antidepressants increased significantly year by year,with SSRIs representing more than 88% of all the antidepressant drugs in terms of the consumptive sum,leading the first 3 places in terms of consumption sum and DDDs were fluoxetine,paroxetine and citalopram.The market share of traditional tricyclics and tetracyclines showed a slight reduction,but there were still a stable population of these drugs.CONCLUSION:SSRIs such as fluoxetine have been dominated the antidepressants market in Beijing area.
