ABSTRACT Objective:To understand the current status of post marketing study of Xiyanping Injection.Methods:The Cochrane library, Medline and Embase with four Chinese databases including CBMDisc, CNKI, VIP and Wanfang data were systematically searched with the keywords "Xiyanping". The relevant information was extracted by two researchers independently and the data were bibliometrics analyzed using SPSS 20.0. Results: A total of 1 598 studies were included, 16.2% of which were published in China Core Journals of Science and Technology. The majority of this medication was used to treat respiratory disease (50.4%), digestive diseases (22.7%) and hand foot and mouth disease(20.5%). The rest was used in surgical conditions, skin diseases or cardiovascular diseases. Most of the routes of administration were intravenous injection (90.8%), while 4.2% were inhalation. The reported proportion of administration rate, administration time and follow up time were all less than 3%. There were 1393 studies (90.5%), involved 105 703 patients, which took Xiyanping injection as core treatment with control group. None of the studies provided the rationale of the sample size. There were 1 431 self reported randomized control trials, and the proportions for incorrect using retrospective data, non reporting detail randomization methods, blind method and allocation concealment were 20.5%, 85.7%, 99.2% and 99.7%, separately. Most of those used ribavirin or blank as control, and among those, 1 256 studies were with only one control group and using general effective rate as evaluation index, 85.8% of which could not be satisfied the required sample size. Conclusion:The post marketing study of Xiyanping injection was with numerous amount but poor design quality, as well as poor reporting quality. It was used in considerable patients with diverse diseases, even existed off label drug use phenomenon. It’s suggested that future studies should make best use of the patients’ resources, and get idea from clinical practice, combined with high quality and large sample design to provide evidence for its efficiency and safety in a variety of situations. Medication industry, government, and periodical association should work together to bring their influencing of supervision and guidance. |
