Objectives: The aim of this study was to investigate the prevalence and its determinants of Antipsychotic Use in patients with psychiatric disorders. Materials and

Methods: This study was on patients with psychiatric disorder that have discharged from the hospital. We have assessed all patients with psychiatric interview and evaluation of their psychiatric documentations.

Results: 90.7% of all of patients had taken antipsychotic medications and antipsychotic polypharmacy was in 27.2% of these patients. The most prevalent component of antipsychotic polypharmacy was consisting of Chlorpromazine, Halopreidol and Chlorpromazine, Risperidone and then Chlorpromazine, Olanzapine respectively. There were significant relations between pattern of antipsychotic use and gender, occupation status, type of psychiatric ward, duration of hospitalization and cost of treatment but no relationship with age, educational status and duration of illness.

Discussion: This study suggests that prevalence of antipsychotic polypharmacy is high in in-patient psychiatric patients.

Objectives: Psychotropic drug use in the elderly with chronic schizophrenia is an important issue in the field of psychiatry. The main goal of this study was to clarify the pattern of such drug use in these patients, in order to consider such therapy plan and focus on its cost attributing measures, for a more reasonable quality of care program.

Methods: In this descriptive study, participants included 52 elderly patients at Tehran’s Razi Mental Hospital who had chronic schizophrenia in the residual phase. Selected patients were taking at least two psychotropic drugs equivalent to 500mg Chlorpromazine. We prepared the list of the drugs used by completing the pre-designed questionnaire charts. Data were analyzed with SPSS 17.

Results: In one case (1.92%) the entries were Risperidone, Chlorpromazine, Fluphenazine Decanoate, & Thiothixene). In 11 cases (21.2%) there were three entries and in 40 cases (76.8%) there were two. The Chlorpromazine equivalent dose in each group ranged from the lowest dose (750 mg) to the highest (5600 mg). The highest Chlorpromazine dose (5600 mg) equivalent per milligram belonged to the four entries of (Risperidone, Chlorpromazine, Fluphenazine Decanoate & Thiothixene). The lowest Chlorpromazine dose (750 mg) was seen in 3 entries of Risperidone, Chlorpromazine & Fluphenazine Decanoate.

Discussion: There was a high prevalence of using more than two psychotropic medications from the first atypical antipsychotic category. Less frequently, the second and the third typical antipsychotics were used. We recommend further research into more feasible patterns of psychotropic prescriptions, lowering the amount of medication use and considering their cost-benefits in the elderly with chronic schizophrenia.
