할로페리돌(HP)은 정신분열증 환자에 널리 사용되는 Dopamine D$_2$-receptor의 antagonist인 antipsychotic drug이다. 이 약물의 혈장농도와 임상 반응사이의 'curvilinear'한 상관성 존재여부와 여기에 대한 대사체(reduced haloperidol, RH)의 영향에 대해 논란은 많지만, 본 연구 팀에서도 위의 상관성이 존재하며 또한 여기에 RH가 영향을 미칠 것으로 보고한바 있다. 따라서 본 연구에서는 앞의 결과에 대한 기전을 밝히고, 궁극적으로 효율적인 뇌송달 시스템의 개발가능성을 검토하기위한 1차적 인구로 HP의 약물속도론적 연구를 사람, 랫트 및 가토에서 실시하여 그특성을 비교하였다. 사람경우는 13명의 정신분열증 초기환자를 대상으로 경구(20mg HP, 5명) 및 주사(10mg HP, 8명) 투여한 후, 또한 랫트 및 가토의 경우는 마리당 5mg의 HP 및 RH를 각각 정맥주사한 후 경시적으로 혈장중 HP 및 RH의 농도를 측정하여 체내동태 특성을 검토하였다.

We report a case of antipsychotics induced torsade de pointes in a 42-year-old female schizophrenic patient. The patient had taken perphenazine 20 mg/day, chlorpromazine 100 mg/day, and trifluoperazine 15 mg/day irregularly for about 8 years. She experienced syncope and a few difficulties in breathing. On EKG(electrocardiography), QT interval was delayed and polymorphic QRS complexes and ventricular tachycardia were observed. Following a switch of the antipsychotics to haloperidol, known to have fewest effects on the cardiac rhythms among antipsychotics, the arhythymias disappeared. However after discharge, as dose of haloperidol was increased, the symptoms such as chest discomforts and syncopes reappeared. We concluded that the torsade de pointes was developed by antipsychotics. The most common cause of sudden death in patients receiving antipsychotic treatment appears to be ventricular tochycardia. Therefore, clinician should be well aware of the possible side effects of antipsychotics and be cautious in prescribing such drugs to their patients.

Although the scientific evidence is not entirely supportive, atypical antipsychotics have been used widely for the treatment of children and adolescents with mental illnesses as alternatives to typical antipsychotics which have more serious unwanted adverse effects than atypical neuroleptics. On the basis of clinical experiences and research data, atypical antipsychotics have been prescribed for adolescents with schizophrenia, manic or mixed episodes of bipolar disorders, tic disorders, aberrant behaviors in pervasive developmental disorders, and impulsive or violent behaviors in disruptive behavior disorders. Due to their efficacy and relatively more tolerable side effects, the use of atypical antipsychotics has become increasingly popular in child and adolescent psychiatry. However, we should pay attention to the limitations associated with short-term clinical experiences and the lack of well-designed controlled studies, especially in terms of adverse effects including those involving metabolic processes.

Successful management of mental symptoms requires proper diagnostic tools and comprehensive treatment including psychotherapy, physical therapy and psychopharmacotherapy. For this purpose. valid and reliable diagnostic instruments need to be developed. and the data regarding various treatment methods in medical and psychiatric comorbid conditions should be available. Because mental symptoms originate from various aspects of biological, psychological and social factors. each aspect may have slightly different therapeutic goal. Alterations in pharmacokinetics and pharmacodynamics of medically ill and/or old patients may complicate the treatment outcomes. Best psychopharmacological treatment needs to be elaborated in various states. Mental symptoms of the medically ill patients may be treated more effectively with an eclectic approach.

Object:The goal of this study was to examine the changes in body weight and glucose levels of the patients treated with risperidone, clozapine or haloperidol in order to compare the effect of risperidone or clozapine with that of haloperidol. Methods:For nine months(January to September, 2003), a prospective study was performed in 60 patients with chronic schizophrenia who were in Seoul National Hospital. Two-week period was required for a drug wash-out. The patients were randomly assigned to risperidone, clozapine and haloperidol groups. They were given risperidone(n=20), clozapine(n=20) and haloperidol(n=20), respectively, everyday for 12 weeks. To examine the effects of these drugs on body weight and fasting glucose levels, we measured body weight and glucose levels of all the patients first without the drug treatment and at each end of 4, 8, and 12-week periods with the treatment. And we examined the differences among three groups in the changes of body weight and fasting glucose levels. Results:There were no significant differences in the changes of the body weight and fasting glucose levels between the atypical antipsychotics(risperidone or clozapine) and the typical antipsychotics(haloperidol). Conclusion:The study in the patients with chronic schizophrenia suggests that risperidone or clozapine do not cause any additional effects on body weight or glucose levels compared to haloperidol.

While the therapeutic efficacy of antipsychotic drugs is not in doubt, a variety of undesirable side effects are common. They can be a disincentive to good compliance with treatment, resulting in increased possibilities for relapse and hospitalization. They can be distressing and disabling and thus interfering with patient safety and quality of life. Furthermore, they may be counter-therapeutic by exacerbating the condition that the drug was prescribed for. In this article, we will provide an overview of management of antipsychotic- induced side effects, with a particular emphasis on the most common side effects as well as less common but serious side effects. In addition, some practical issues regarding the management of side effects will be discussed.
