Compared with groups not receiving blood-pressure-lowering drugs, the Polycap reduced systolic blood pressure by 7.4 mm Hg (95% CI 6.1-8.1) and diastolic blood pressure by 5.6 mm Hg (4.7-6.4), which was similar when three blood-pressure-lowering drugs were used, with or without aspirin. Reductions in blood pressure increased with the number of drugs used (2.2/1.3 mm Hg with one drug, 4.7/3.6 mm Hg with two drugs, and 6.3/4.5 mm Hg with three drugs). Polycap reduced LDL cholesterol by 0.70 mmol/L (95% CI 0.62-0.78), which was less than that with simvastatin alone (0.83 mmol/L, 0.72-0.93; p=0.04); both reductions were greater than for groups without simvastatin (p<0.0001). The reductions in heart rate with Polycap and other groups using atenolol were similar (7.0 beats per min), and both were significantly greater than that in groups without atenolol (p<0.0001). The reductions in 11-dehydrothromboxane B2 were similar with the Polycap (283.1 ng/mmol creatinine, 95% CI 229.1-337.0) compared with the three blood-pressure-lowering drugs plus aspirin (350.0 ng/mmol creatinine, 294.6-404.0), and aspirin alone (348.8 ng/mmol creatinine, 277.6-419.9) compared with groups without aspirin. Tolerability of the Polycap was similar to that of other treatments, with no evidence of increasing intolerability with increasing number of active components in one pill. This Polycap formulation could be conveniently used to reduce multiple risk factors and cardiovascular risk.
