ABSTRACT
OBJECTIVE To analyze the clinical manifestations and characteristics of adverse drug reactions （ADR） induced by dronedarone，and to provide reference for clinically safe drug use. METHODS Retrieved from PubMed database， Wanfang database，CNKI and VIP （up to August 31st， 2022），ADR cases of dronedarone were analyzed retrospectively in respect of patient’s age，gender，nationality，usage and dosage of dronedarone，and occurrence time，clinical manifestations，treatment measures and outcome of ADR，etc. RESULTS A total of 26 case reports were included，with a total of 27 patients. The age of the patients was 41-86 years old，with an average age of 68.8 years. The proportion of patients aged 60-79 was the largest （20 cases，74.1%）. There was no significant difference in the number of males （14 cases） and females （13 cases）. The patients came from 6 countries， of which the United States was the largest （16 cases，59.3%）. The dosage of 14 patients was 400 mg bid；one patient was 200 mg bid；the dosage for 12 patients was not specified. The most ADR cases （16 cases，59.3%） occurred within 1 month，of which 11 cases（40.7%） occurred within 1 week，and there were no ADR reports with medication more than 12 months. Organs/systems involved in ADRs were mainly liver and biliary diseases （7 case times，23.3%），skin and subcutaneous tissue diseases （6 case times， 20.0%），respiratory tract，thoracic and mediastinal diseases （5 case times，16.7%）. In addition，ADR also occurred in heart diseases， kidney and urinary system diseases，vascular diseases，medical examinations and eye diseases. Among 27 patients，there were 3 cases of death，the ADR were bronchiolitis obliterans with organizing pneumonia，toxic epidermal necrolysis and hepatic failure， respectively. One patient underwent liver transplantation. CONCLUSIONS Dronedarone can cause multiple organ system ADR. Before use，it is necessary to improve the examination including ECG，liver function，lung function，etc. and strengthen drug use monitoring within one month after the start of use，especially the ADR of hepatobiliary，skin and respiratory system. The occurrence of severe ADR has no obvious relationship with the duration of medication； even if it is taken safely for a long time，it still needs continuous pharmaceutical monitoring and follow-up to ensure the clinical medication safety of patients.
