Objective To understand the current state and problems of the use of prescription antibacterial drugs of our outpatient department

and to provide references for a rational clinical application of antibacterial drugs.Method Take 3 482 prescription copies of the outpatient department of Guangdong University of Foreign Studies from January to December 2013 at random

and conduct a statistical analysis of the state of use of antibacterial drugs by means of Excel form.Results The rate of using prescription antibacterial drugs at our outpatient department was 35.6%

and the main ways of use were oral intake（94.6%）and single medication（83.1%）.The top three in the ranking list of the times and frequency of medication were amoxil capsule

archie enzyme tablet

and cephradin capsule.The former two have a higher DUI while acetylspiramycin enzyme tablet

tinidazole injection
