ABSTRACT Objective:To understand the current level and characteristics of adverse drug reaction in Post marketing study of Xiyanping injection. Methods:The Cochrane library, Medline and Embase with four Chinese databases including SinoMed, CNKI, VIP and WanFang Data were systematically seolrched, with the keywords “Xiyanping”. The relevant information was extracted by two researchers independently and the data were analyzed using Stata 14.0. Results: A total of 1 587 studies were included, 90.2% of which were claimed as randomized controlled trial. There were 1 778 patient groups medicated with Xiyanping injection, 46.3% of which reported information about adverse drug reaction. About 1 244 patients with adverse drug reaction were extracted from above studies, which concluded with digestive system damage (40.7%), skin and its accessories damage (23.6%), pain at the application site (8.4%). However, little information was reported about the related drugs and treatment measures. The overall incidence rate of adverse drug reaction for Xiyanping injection was 1.8% (95% confidence interval: 1.7% 2.1%) based on a total of 62 464 patients. After Meta regression, the incidence rates for the follow up studies without control group and for the infants aged less than one year old were significantly lower, whereas the incidence rates for the patients medicated with Xiyanping injection at least twice a day or at least seven days and for patients treated together with anti biotics or other Chinese patent drugs were significantly higher. Conclusion:Given that it might increase the risk of adverse drug reaction while using Xiyanping injection with higher frequency, longer duration, or together with other medications, we suggested that the clinicians should try their best to avoid above conditions. Meanwhile, it’s highly recommended to make the best use of electronic health records to conduct more big scale active surveillance targeted for children. In addition, the issue of poor quality for the Post marketing studies of Xiyanping injection should receive adequate attention from the related researchers, industry, periodical association, and government, whom are responsible for creating a positive atmosphere for high quality studies. |
