Polypill: Progress and Challenges to Global Use--Update on the Trials and Policy Implementation.

Cardiovascular disease (CVD) is the leading cause of mortality globally. Most people with cardiovascular disease do not take long-term cholesterol-lowering, anti-platelet and blood pressure-lowering medications despite proven benefits. Fixed-dose combination pills ('polypills') have been shown to improve adherence to these recommended medications with corresponding improvements in risk factors such as blood pressure and low-density lipoprotein (LDL) cholesterol. Among patients not taking the full complement of recommended CVD preventive therapies, use of a polypill-based strategy (i.e. initiating treatment with single-pill combination medication then titrating further therapy as needed) has large potential benefits in reducing global morbidity and mortality. Despite this, few polypills are available on the market due to market failure in the funding of research and development for affordable non-communicable disease medicines. Additionally, defining a path to market has been problematic in that fixed-dose combinations with multiple different drug classes included are quite novel, and regulatory processes to review these types of applications are not well established. Despite these delays, progress is slowly being made.
