Abstract: Objective： Using ABC analysis and DDDs to analyze the drug usage in a university hospital， providing a reference for clinical rational drug use. Methods： Using the ABC analysis method and DDDs to statistically analyze the withdrawal amounts of drugs and the usage of drug varieties in the university hospital， with a focused analysis on Class A drugs. Results： In 2019， the hospital dispensed a total of 383 drug varieties. Class A， B， and C drugs accounted for 13.84%， 17.75%， and 68.41% of the total varieties， respectively， while their corresponding proportions of the drugs withdrawal amounts were 75.28%， 16.40%， and 8.32%. Class A drugs are were divided into 10 categories. Class A drugs are were mainly Chinese patent medicines and cardiovascular system drugs， with the cumulative proportion of varieties and withdrawal amounts accounting for 56.60% and 60.17%， respectively. Within Class A drugs， the administration methods for Chinese patent medicines were divided into internal and external use and， the top 10 drugs in terms of withdrawal amounts were mainly classified into granules， capsules， tablets， and oral liquids. There were 8 cardiovascular drug varieties， with 7 of them being antihypertensive agents. Conclusion： The overall drug utilization structure in the hospital was relatively rational. Although there were not many class A drugs， their withdrawal amounts were the highest. Therefore， the management and use of these drugs， especially Chinese patent medicines and cardiovascular system drugs， were the focus of attention. It is necessary to continuously strengthen the supervision and regulation of the use of these drugs to ensure their rational and safe application.
