Correlation of polypill and blood pressure level: A systematic review of clinical trials

BACKGROUND: High blood pressure (BP) is considered as the most important risk factor for cardiovascular disease (CVD). The main aim of this study was to investigate the effect of polypill on BP by reviewing clinical trial studies. MATERIALS AND METHODS: In this systematic review study, online databases such as PubMed, Scopus, and Web of Science databases with no limited time were systematically searched until July 10, 2020. Clinical trial studies published in English that examined the effect of polypill on BP were included. BP was the main outcome investigated. RESULTS: Eleven original articles with a population of 17,042 people were reviewed. The polypill drugs studied in this study had different compounds. Compared to conventional care, treatment with polypill compounds has a positive and significant effect on lowering BP (P < 0.05). CONCLUSION: Our finding confirmed that polypills could reduce BP in patients. It seems that changing routine care and replacing it with a polypill strategy could facilitate the achievement of BP control goals.
