左氧氟沙星注射剂不良反应与合理性用药的前瞻性观察

目的：了解住院病人使用左氧氟沙星注射剂的不良反应发生率和合理性用药。方法：前瞻性观察北京市7家医院中使用左氧氟沙星注射剂的全部住院病人，结果：2661例用药者中发生不良反应105例，不良反应发生率为3．9％，其中重度不良反应占4．8％，全部是二重感染。不良反应的发生与年龄、用药不合理、合并用药和既往过敏史有关。左氧氟沙星不合理用药占19．9％，集中于60岁以上的老年人群，主要问题为用药时间不合理（疗程过长或过程）。结论：左氧氟沙星注射剂在临床上应用比较安全，但要注意合并用药问题和老年人的用药安全性。不合理用药是导致不良反应发生率增加的直接原因。

Adverse drug reaction and rational use of levof loxacin:A perspective study

Objective To study the rate of adverse drug reaction(ADR) and the rational use of levofloxacin among in patients. Method All in patients treated with levofloxacin were prospectively observed in 7 hospitals of Beijing. Results One hundred and five ADR cases were found in 2 661 patients injected with levofloxacin. The ADR rate was 3.9 % while 4.8 % of them were classified as severe cases. All severe ADR cases had a nature of double infections. The ADR occurrence was related to older age, irrational drug use, combined medicine and allergic history. The rate of levofloxacin irrational use was 19.9 %, especially in the elderly population, due to too long or too short course of treatments. Conclusion Levofloxacin is viewed as a safe injection in clinical practice, however, combined medicine and elderly patients should be paid more attention when on administration of this medication. The irrational use of levofloxacin was recognized as one of the main reasons causing the increase of ADR.
