METHODS:Using the Excel statistics and manual screening,528 ADR reports were collected from a third grade class A hospital in Chongqing during Oct. 2005 to Dec. 2015. Those ADR cases were analyzed statistically in respects of general information of ADR patients, routes of administration and occurence time,types of ADR-inducing drugs,organs/systems involved in ADR and clinical manifesta-tions,disposal and outcomes,etc. RESULTS:A total of 285 cases(53.98%)of ADR occurred in elderly patients aged more than 65. Most of original diseases were respiratory system disease(144 cases,27.27%). 124 ADR cases occurred in people who had al-lergic history(23.48%).
