Pseudoallergic reactions of traditional chinese medicine injections and the approaches for risk prevention and control / 中国药学杂志

ABSTRACT

Allergic hypersensitivity reactions (AHRs) are the most commonly reported adverse reactions of traditional Chinese medicine injections, mainly including skin and mucosa redness, itching, abdominal pain, chest tightness, dyspnea and nausea, blood pressure decline, with clinical symptoms, and even shock or death. In this paper, we analyzed the characteristics of clinical adverse reactions and preclinical study results of traditional Chinese medicine injections, and proposed a view of point that the main adverse reactions of traditional Chinese medicine injections are nonallergic hypersensitivity reactions (NHRs) or pseudoallergic reactions (PARs) instead of real AHRs. Because there are absolute differences in the characteristics and the pathogenesis mechanisms between PARs and AHRs, they should not be confused, otherwise, the clinical processing measures and the direction of basic research on the adverse reactions of traditional Chinese medicine injections would be misleading. This paper also discussed the approaches for risk prevention and control of PARs of traditional Chinese medicine injections.
