Sažetak

Background: A comprehensive insight into drug utilization as an economic and primarily a public health issue can only be acquired in the context of overall health state of the respective population. The objectives of the study were: 1) to determine the real outpatient utilization of psychopharmaceuticals in Zagreb, 2) to determine the psychopharmaceutical prescribing quality during the study period; and 3) to propose appropriate interventions in Zagreb on the basis of the results obtained.
Subjects and methods: Data on drug utilization were obtained from all Zagreb pharmacies. The number of defined daily doses (DDD) and number of DDD per 1000 inhabitants per day (DDD/1000/day) were calculated from the number of particular drug packages. The Drug Utilization 90% (DU90%) method was used as a criterion of prescribing quality.
Results: Outpatient utilization of psychopharmaceuticals showed a declining pattern from 115.40 DDD/1000/day in 2001 to 93.15 DDD/1000/day in 2006. Anxiolytics accounted for the majority of this drug group utilization in the City of Zagreb, although the anxiolytic/antidepressant ratio decreased from 7.19 in 2001 to 3.86 in 2006. The utilization of selective serotonin reuptake inhibitors showed a 2.5- fold increase and accounted for 90% of overall antidepressant utilization. A 2.5-fold decrease was recorded in the utilization of antipsychotics, while the atypical/typical antipsychotic ratio changed from 1:2 in 2001 to 1.1:1 in 2006.
Conclusion: Despite some improvement observed in the prescribing quality, the predominance of benzodiazepines in the utilization of psychopharmaceuticals points to the need of additional rationalization in the field.
