Polypill has been proposed as an efficient strategy for primary and secondary cardiovascular prevention. It has been shown that a fixed dose combination therapy improves adherence compared to usual treatment.
There are two recent interesting papers regarding the use of Polypill.
The first one1 is a study of the adherence and effects of a Polypill (Atorvastatin 10mg, Amlodi pine 2,5mg losartan 25mg and hydrochlorothiazide 12,5mg) prescribed to 303 adults, 96% black, in an underserved population with an annual income below $ 15000 US dollars. Adherence, based on pill counts was 86%. Compared to usual care a decrease of a mean systolic pressure of 9 mmHg versus 2mmHg and a decrease of LDL cholesterol of 15mg/dl versus 4 mg /dl, with the Polypill was observed. These results, if sustained would lead to a 25% relative reduction in the estimated cardiovascular risk as compared with those assigned to receive usual care, at a monthly cost of $26 US dollars. In spite of some limitations these results confirm previous findings of a good adherence to Polypill and potential clinical impact, and they are particularly important since the trial involved a low income, minority population
The second paper2 is a trial in 6838 individuals, 40 to 75 years of age, half treated with a non pharmacologic approach and the other half adding to this a Polypill (Atorvastin 20mg, Enalapril 5 mg, hydrochlorothiazide 12,5mg and Aspirin 81mg; in a subgroup Enalapril was replaced by Valsartan 40mg). Adherence to the polypill was 80.5%. In the first group, 8.8% had a major cardiovascular event (HR 0.61) without statistic difference between absence or presence of preexisting cardiovascular disease. With better adherence reduction of cardiovascular events was even better (HR 0.43) It was concluded that a low cost polypill should be considered as strategy of prevention particularly in low and middle income countries
