ObjectivesTo systematically review the influence of nifedipine combined with atorvastatin on hypertension in patients with hypertension.MethodPubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect randomized controlled trials (RCTs) of nifedipine combined with atorvastatin on hypertension in patients with hypertension from inception to November 20th, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 17 RCTs involving 1 838 patients were included. The results of meta-analysis indicated that nifedipine combined with atorvastatin was superior to nifedipine alone on SBP (MD=?8.937, 95%CI?11.913 to ?5.962, P<0.001), DBP (MD=?3.702, 95%CI?6.626 to ?0.778, P=0.013) and total effective rate (RR=1.24, 95%CI 1.07 to 1.44, P=0.003). There was no significant difference between two groups in the incidence of adverse reactions (P>0.05).ConclusionsCurrent evidence shows that nifedipine combined with atorvastatin can significantly improve total effective rate, decrease the level of SBP and DBP, and increasing of dose not increase the incidence of adverse reactions. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
