Abstract: Objective To explore the causes and regularity of the adverse reactions (ADRs) of troxerutin , in order to provide the scientific references for safe drug use in clinic. Methods 61 cases of the ADRs of troxerutin reported in domestic literature were analyzed. Results Among 61 cases of the ADRs of troxerutin, more than 80% occurred in the age group above 45 years and 55.7% happened after the drug was taken beyond indications showed in the instructions. Futhermore, among 57 cases accepting intravenous drop infusion, 68% used glucose injection as solvent, and the ADRs of the solvent were more risky than that of other solvents. In addition, 22% occurred when troxerutin was used combining with other drugs in the same infusion bottle. 77% happened within 30 minutes after the drug was taken. Finally, the main ADRs were anaphylactic and anaphylactoid reactions. Conclusion Medical staff should well know instructions of the drugs, use it in accordance with the indications and doses labeled in the instructions strictly, and be cautious of drug combination. Furthermore, it is prohibited to use the drug combining with other drugs in the same infusion bottle. Meanwhile, the drug should be used under strict monitoring to reduce the damage caused by ADRs to a minimum.Pharmaceutical manufacturers should strengthen researches on preparation quality control and safety of troxerutin, so as to revise and improve the instructions on safety of the drugs.
