We review clinical trials and observational studies evaluating the impact of the polypill on reducing the incidence of major cardiovascular events (MACEs), its influence on medication adherence, and its potential to fill treatment gaps in diverse populations. Also of note are the pharmacoeconomic implications of the widespread use of the polypill, particularly in low- and middle-income countries where the burden of cardiovascular disease is increasing.

This review summarizes the current evidence on the efficacy, safety, and cost-effectiveness of the polypill in CVD primary and secondary prevention.
