INTRODUCTION AND OBJECTIVES:To compare the pharmacodynamics of the CNIC polypill (atorvastatin 40mg/ramipril 10mg/aspirin 100mg) in terms of low-density lipoprotein cholesterol (LDL-C) and systolic blood pressure (SBP), with the corresponding reference products (atorvastatin and ramipril). METHODS:This was a multicenter, randomized, open-label, and parallel 3-arm study comparing the effect of the CNIC polypill vs ramipril 10mg and atorvastatin 40mg on SBP and LDL-C. The coprimary endpoints were differences in the adjusted mean 24-hour SBP (using ambulatory BP measurement) and LDL-C during the study period estimated using an ANCOVA model. RESULTS:Of the 241 patients included in the per protocol population, 84 received the CNIC polypill (group A), 84 atorvastatin (group B), and 73 ramipril (group C). SBP decreased from 139.3±12.5 to 133.2±12.9mmHg in group A and from 138.1±11.9 to 134.0±12.8mmHg in group C (baseline adjusted mean difference for the decrease in SBP was 1.77mmHg (90%CI, -0.5 to 4.0) in favor of group A, without reaching statistical significance. LDL-C was reduced by 33.9±21.6 and 29.2±25.8mg/dL in groups A and B, respectively (baseline adjusted mean difference for the decrease in LDL-C was 7.0% (90%CI, 1.5-12.4), a significantly greater decrease with the polypill). The 3 treatments were well tolerated. CONCLUSIONS:The results of this study rule out a negative effect on blood pressure of the interaction between the components of the CNIC polypill. The reduction in LDL-C was greater in the CNIC polypill group, suggesting a synergistic effect of the components.
