The effects of fixed-dose combination therapy on all-cause mortality or ASCVD events are uncertain .
A limited number of trials reported these outcomes , and the included trials were primarily design ed to observe changes in ASCVD risk factor levels rather than clinical events , which may partially explain the observed differences in risk factors that were not translated into differences in clinical outcomes among the included trials .
Fixed-dose combination therapy is associated with modest increases in adverse events compared with placebo , active comparator , or usual care but may be associated with improved adherence to a multidrug regimen .
Ongoing , longer-term trials of fixed-dose combination therapy will help demonstrate whether short-term changes in risk factors might be maintained and lead to expected differences in clinical events based on these changes
BACKGROUND Atherosclerotic cardiovascular disease ( ASCVD ) is the leading cause of death and disability worldwide , yet ASCVD risk factor control and secondary prevention rates remain low .
A fixed-dose combination of blood pressure- and cholesterol-lowering and antiplatelet treatments into a single pill , or polypill , has been proposed as one strategy to reduce the global burden of ASCVD .
OBJECTIVES To determine the effect of fixed-dose combination therapy on all-cause mortality , fatal and non-fatal ASCVD events , and adverse events .
We also sought to determine the effect of fixed-dose combination therapy on blood pressure , lipids , adherence , discontinuation rates , health-related quality of life , and costs .
IMProving Adherence using Combination Therapy (IMPACT): design and protocol of a randomised controlled trial in primary care.
BACKGROUND Cardiovascular disease ( CVD ) is the leading cause of death , and principal reason for the large difference in life expectancy between indigenous Māori and the non-indigenous population in New Zeal and . CVD guidelines recommend that people who are at high risk or who have had previous CVD should be offered aspirin , blood pressure lowering and lipid lowering therapies . However , prescribing and adherence rates are low and CVD events remain high . AIM To assess whether a medication strategy using a fixed dose combination pill ( ' polypill ' ) could improve prescribing and adherence to recommended medications , lower blood pressure and improve lipids compared with current care over 12 months . METHODS IMProving Adherence using Combination Therapy ( IMPACT ) is an open-label r and omised controlled trial comparing a once-daily polypill containing four preventive medications with usual care .  Six hundred participants who have had previous CVD events or are at high risk of CVD will be enrolled , including 300 Māori . Participants are identified , enrolled and prescribed either the polypill or current medications at their usual primary health care practice , with medications ( including the polypill ) dispensed through local community pharmacies . The polypill contains 75 mg aspirin , 40 mg simvastatin , 10 mg lisinopril and either 12.5 mg hydrochlorothiazide or 50 mg atenolol . Primary outcomes are adherence to guidelines -recommended medications and changes in systolic blood pressure and low density lipoprotein at 12 months . Secondary outcomes include other lipids , medication dispensing , barriers to adherence , CVD and other serious adverse events , quality of life and prescriber acceptability . The trial is registered with the Australian New Zeal and Clinical Trial Registry ( ACTRN12606000067572 )
