A total of 109 varieties of Chinese medicine injections (CMI) have been approved by the State Food and Drug Administration of China, all of which have the potential to induce adverse drug reactions (ADRs). Major ADRs include systemic anaphylaxis, anaphylactic shock, acute intravascular hemolysis, hepatorenal damage, skin lesion, cardiac damage, respiratory system injury, and gastrointestinal disorders. Contributing factors of ADRs include healthcare workers' inadequate attention to ADRs of CMI, complex ingredients, allergic uncertainties, and inappropriate drug use in children and the aged. To decrease ADRs resulting from CMI, it is essential to improve the selection of drug indications, delivery of proper dosage regimens, compliance with drug instructions, and selection of solvents for the drugs.

The relevant information of ADRs for Ciwujia injection was insufficiently reported in included studies. The ADR type distribution between clinical studies and ADR reports was inconsistency. Most of the reported ADRs were mild, and were treated successfully by slowing down the drip velocity or by withdrawing the drug and treating the symptoms. As Ciwujia injection was one of the highest numbers of ADR reports of traditional Chinese medicine injections, high quality ADR monitoring, standardized ADR reporting, and timely analysis risk factors of ADRs are extremely urgent.

Objective To systematically assess the main clinical features of Houttuynia injection-associated adverse drug reactions (ADRs), as described in published reports, and to contribute to the post-marketing re-evaluation and clinical practices of Houttuynia injection. Method We searched the electronic databases-PubMed, EMBASE, the Chinese National Knowledge Infrastructure (CNKI), the Chinese Science and Technology Journal Full-text Database (VIP) and the Chinese Biomedical Disc (CBMdisc), for articles published through June 2010. We then extracted and analyzed the data. Results A total of 645 articles were included, with a total of 1232 ADR cases reported. Respiratory diseases accounted for 52.44% of all cases of Houttuynia injection ADRs, followed by reproductive system diseases (4.30%) and urinary system diseases (3.73%). Multiple systems or organs were involved in the ADRs, the top five were: respiratory system (37.42%), skin (34.66%), digestive system (25.49%), circulatory system (25.41%), and nervous system (23.96%). Serious systemic adverse reactions accounted for 22.56% of total ADRs. Of the reported 1,232 ADR cases, 286 ADR cases reported previous allergies in detail; allergy to penicillin accounted for 15.03% of the total cases with the allergic history, followed by unknown drugs (8.05%), and sulfonamides (3.15%). Among the ADR cases, Houttuynia injection was commonly used together with cephalosporins, penicillins, and macrolides. Macrolides combined with Houttuynia injection showed higher ADR risk than Houttuynia injection used alone (RR = 8.80, 95% CI 6.12 to 12.65, P < 0.0001). The ADR risk for intravenous injection of Houttuynia injection was higher than that of intramuscular injection (OR = 6.86, 95% CI 1.88 to 56.95, P = 0.0016). We used the WHO ADR Classification Criteria to divide the ADR cases into four grades. There were 22.56%, 36.28%, 16.48%, and 24.68% cases of Grade I, II, III, and IV, respectively. Anaphylactic shock accounted for 58.99% of the most serious ADRs (Grade I). All cases of death were caused by allergic shock, except one, who died of multiple organ failure caused by anaphylactic purpura. The fastest-onset three ADR cases occurred in one minute after injection. Conclusion The respiratory system was the most common system treated in Houttuynia injection ADR cases. It was also the most common site of ADR symptoms. The ADRs of Houttuynia injection were serious. The precautions should be taken to prevent the anaphylactic shock. Intravenous injection and the combination with with cephalosporins, penicillins, and macrolides increased the ADR risk of Houttuynia injection.

PYG used to treat BS-QDC is effective and safe, it's effect is similar to that of RDP.

Clearly report adverse effect or adverse event occurred in the clinical practice is very important for understanding the potential risk of using a drug for treatment of diseases, and with other advantages. This document aims to help healthcare providers to organize, report, and publish information on ADR/AE occurrences and to identify the nature of the ADR/AE in TCM and integrative medicine practice. This document provides recommendations on constructing a title, basic factors of writing an abstract and the text of ADR/AE reporting. In each part, there are some samples could be references for the development of a report and ADR/AE. We welcome any comments for improving this recommendation.

AM could increase the expression of T-bet mRNA and Thl cytokines such as IFN-Y, and might reverse the Th2 predominant status in asthma patients.
