Abstract:

In mainland China, some researchers has begun with pharmacovigilance study on Traditional Chinese medicine adverse drug reactions (ADRs), for usual methods can�t be used to detect those potential risk factors or signals of ADRs in time. 20,000 cases of ADRs were collected from China State Food and Drug Administration (SFDA) ADR surveillance database from 2001to 2009 and were described. Three classic ADR signals detection pharmacovigilance methods were used in this study to analyze selected data about Yuxingcao injection from Jan. 2005 to Apr. 2007. Three methods are reporting odds ratio (ROR), proportional reporting ratio (PRR) and bayesian confidence propagation neural network (BCPNN). Risk signals were detected at four quarters of the year 2005 by ROR and PRR and from the third quarter of the year 2005 by BCPNN. And all signals were detected at the first quarter, the second quarter and the fourth quarter of the year 2006 by three methods. All signals were the same found by ROR and PRR, but a little different from BCPNN. The date of detecting these signals and their developing trend were the same with stopping using Yuxingcao injection time by China SFDA. Pharmacovigilance analysis should be based on reliable ADRs reporting timely. A real-time surveillance on ADRs of post- marked Traditional Chinese Medicine needs huge massive data sets from the real word. Meanwhile, confounder controlling and data standardizing should be considered carefully during statistic analysis and data mining.
