Pharmacodynamic study of the cardiovascular polypill. Is there any interaction among the monocomponents?

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). 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. 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. 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.

Estudio multicéntrico, aleatorizado, abierto, de 3 grupos paralelos, que comparó el efecto del policomprimido CNIC frente a ramipril 10mg y atorvastatina 40mg sobre la PAS y c-LDL. Los objetivos coprimarios fueron las diferencias en las medias ajustadas de PAS 24h (mediante monitorización ambulatoria de PA) y el c-LDL durante el estudio, mediante un modelo ANCOVA. De los 241 pacientes en la población por protocolo, 84 recibieron policomprimido CNIC (grupo A), 84 atorvastatina (grupo B), y 73 ramipril (grupo C). La PAS se redujo de 139,3 (12,5) a 133,2 (12,9) mmHg en el grupo A y de 138,1 (11,9) a 134,0 (12,8) mmHg en el grupo C (diferencia media ajustada de PAS desde niv
