Analysis on 315 cases of clinical adverse drug reaction/event induced by gastrodin / 中国中药杂志

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Reevaluation on adverse reaction monitoring and safety of proprietary Chinese medicines of Chongqing from 2005 to 2011 / 中国中药杂志

<p><b>OBJECTIVE</b>To systematically summarize the monitoring over adverse reactions of proprietary Chinese medicines, in order to provide reference for safe clinical medication.</p><p><b>METHOD</b>By using Excel and SPSS 17.0 were adopted for summarizing ADR monitoring over Chinese patent medicines and comparatively evaluating the non-proprietary Chinese medicines.</p><p><b>RESULT AND CONCLUSION</b>There were significant differences in data of different state reports of proprietary Chinese medicines and non-proprietary Chinese medicines (P<0.05). The ratio between the serious ADR of proprietary Chinese medicines and the safety risk of non-proprietary Chinese medicines was 1.057 (95% CI:0.915, 1. 221), suggesting that the safety of proprietary Chinese medicines was not higher than the non-proprietary Chinese; as such medicines as Qingkailing, Xuesaitong and Xiangdan have ranked top five for years in terms of ADR and serious ADR, the drug administration and hygiene system shall take more effective control measures for strengthening the monitoring over rational use of drugs; clinical manifestations of severe ADR of proprietary Chinese medicines were dominated by allergic shock, which could not be effectively prevented and monitored by such means as skin test, therefore, pre-clinical treatment risk-benefit evaluation shall be improved.</p>
