Objective   To analyze the clinical application, ADR/AE involved systems and manifestations of the six injections containing Houttuynia cordata which are much complicated in their ingredients and pharmacological actions compared with the Houttuynia cordata Injection, and to assess their safety and efficacy, so as to provide references for further deep research.
Methods  Such databases as MEDLINE (1998 to December 31, 2010), EMBASE (1998 to December 31, 2010), The Cochrane Library (1998 to December 31, 2010), CNKI (1979 to December 31, 2010), CBM (1978 to December 31, 2010), and VIP (1989 to December 31, 2010) were searched to retrieve the case report, series of cases observation, cross-sectional study, and clinical control study. The studies were included according to the inclusive and exclusive criteria, and the data was abstracted to analyze the reason and regularity of ADR/AE. Meta-analyses for efficacy were conducted when the data was feasible.
Results  a) About ADR/AE: Among the included 132 studies, 118 cases were reported with the ADR/AE. There were 59 studies about the New Houttuyfonate sodium injection, 93 cases with ADR/AE mainly manifested as pain in injection site (41 cases), rash (19 cases), anaphylactic shock (11 cases) and other infusion or allergic reactions (21 cases). There were 69 studies about the Yu Jin injection, 25 cases with ADR/AE manifested as rash (12 cases), anaphylactic shock (four cases), pain in injection site (three cases), and other infusion or allergic reactions (six cases); and b) The good efficacy of the New Houttuyfonate sodium injection and the Yu Jin injection was reported in one cross-sectional study and one RCT respectively, but the limited data was not enough to properly judge the efficacy.
Conclusion  There are few of clinical studies about these six injections containing Houttuynia cordata, and the irrational use in clinic is serious. Most of the ADR/AE cases are related to irrational use, such as, non-indication use, and arbitrarily change of administration method. The proof for analyzing and evaluating the safety and efficacy of injections containing Houtturnia cordata is insufficient, so strict clinical trials with large sample size are required to support further research.
