Abstract: Objective To investigate the situation of adverse drug reaction/event(ADR/ADE) of Terazosin, and provide bases and references for rational use of Terazosin. Methods 92 ADR reports of Terazosin were collected and analyzed in a hospital from 2006 to 2010. Results In 92 reports, males were far more than females. Adult patients that older than 50 years were accounted for the majority(66.3%). The damage to the nervous system and cardiovascular system were the commonest type. Conclusion We should pay attention to the ADR/ADE of Terazosin, and strengthen the supervision of clinical application of Terazosin.
