Compound danshen dripping pills combined with trimetazidine in treating unstable angina pectoris: Protocol for a systematic review of randomized controlled trials

Abstract

Background:Compound danshen dripping pills (CDDP) and trimetazidine (TMZ) are commonly used in the treatment of unstable angina pectoris (UAP). Currently, the combination of CDDP and TMZ has been widely used for UAP. However, the clinical evidence CDDP combined with TMZ for treating UAP is not sufficient.Methods:We searched for randomized controlled trials testing CDDP combined with TMZ for the treatment of UAP in Chinese National Knowledge Infrastructure database, VIP database, Chinese Biological and Medicine database, Wangfang database, MEDLINE, EMBASE, Cochrane Library, and Web of Science. Extracted data are analyzed using Review Manager 5.3 software. The quality evaluation, forest plots and funnel plots will be conducted by RevMan5.3 software. Moreover, subgroup analysis and sensitivity analysis will also be completed by RevMan5.3.Results:This systematic review will provide powerful clinical evidence of combination CDDP and TMZ for treating UAP.Conclusions:This systematic review will be provided up-to-date clinical evidence to evaluate the effectiveness and safety of CDDP combined with TMZ for the treatment of parents with UAP.Registration Number: PROSPERO CRD42019143100.
