OBJECTIVES: Preventable adverse drug reactions (ADRs) are some of the most common consequences of medication errors (MEs). Database of ADR reports can provide information on wide range of different adverse events and other medication related problems including MEs. The aim of this study was to identify MEs from ADR reports in the Thai Food and Drug Administration (Thai FDA) database. METHODS: ADR reports of Statin drugs in the Thai FDA database between 1993 and 2009 were retrospectively analyzed. Reports were assessed for identifying MEs regarding type of MEs that caused ADR and the subsequent adverse outcome. RESULTS: Of the 1682 reports assessed, 74 reports (4.40%) were identified as MEs that caused ADR. Regarding the type of MEs, most of them were related to failure to adjust for drug-drug interaction (86.5%) following by overdose (13.5%). Among 74 ADRs resulting from MEs, 49 (66%) were serious outcomes and 25 (34%) were considered as non serious outcomes. CONCLUSIONS: Analysis of ADR database identified circumstances that are most prone to errors. This capacity can contribute to the detection and prevention of medication related problems, therefore enhance patient safety.
