A combination pill,  a so-called ‘polypill’, that contains low doses of multiple medications with proven effectiveness for the prevention of cardiovascular disease led to greater reductions in systolic blood pressure and LDL cholesterol level than were observed with usual care in a socioeconomically deprived minority population.
