Background summary
In clinical practice, antihypertensives are generally prescribed for use in the
morning, whereas some statins are recommended for use in the evening. There is
evidence that the reduction in LDL achieved with some statins is superior when
taken in the night, but it is unclear whether the additional reduction in LDL
(and the reported improvement in BP control when aspirin is taken in the
evening) is offset by a reduction in adherence when taking medication in the
evening. Current product labelling recommends night use for simvastatin and
does not state a timing preference for aspirin or blood pressure lowering
medicines. There is therefore uncertainty concerning the best timing of
administration of the polypill. This uncertainty will be addressed by this
trial.
Study objective
The aim of the study is to measure whether there is a difference in LDL
cholesterol levels or the 24 hour ambulatory blood pressure in individuals at
high risk of cardiovascular disease when the polypill is taken in the morning
compared with the evening.
Study design
Randomized cross-over study with 75 participants.
Intervention
Eligible individuals willing to participate in the trial will receive the
polypill and the components of the polypill for a total of 18 weeks; a random
sequence of 6 weeks morning, 6 weeks evening administration and 6 weeks
administration of the individual agents. After every treatment sequence
laboratory blood examination and ambulatory blood measurements will be
performed.
Study burden and risks
Measurements:
None of the study measurements are dangerous. Routine blood samples taken may
be associated with somen bruising, discomfort and local irritation. There is
also a smal risk of infection whenever the skinbarrier is broken by a needle.
The ABPM may be incomfortable due to 24 hours measurement every 30 minutes,
including at night. This last measurement may be inconvenient.
Medication:
The polypill combination cardiovascular medication will be an unapproved
medication. However all the ingredients in both of the polypill combinations
used in this trial are well knowm midicines with well established efficacy and
safety profiles. Although all the drugs in the polypill haven been used for
many years there are possible risks that both polypill may cause side effects.
These are generally mild and infrequent and are usally resolved immediatly by
stopping the medication. Side effects of the components of the polypills can
include low bloodpressure, dizziness, headache, nausea, mild stomach pain,
heartburn, ulceration, abdominal pain, constipation, flatulance, bleeding,
gout, cough, fatique, liver problems, ans muscle pain, tenderness or weakness.
As with any medication an allergic reaction is possible such as skin rash,
itching, difficulty breathing or swelling of the face, but this is quite rare.

Inclusion criteria
Adults with
(A) established atherothrombotic cardiovascular disease (CVD)- history of ischaemic heart disease, ischaemic stroke or transient ischaemic attack, or peripheral vascular disease
OR
(B) a 5 year cardiocvascular risk of at least 5% (SCORE)
Exclusion criteria
Individuals will NOT be eligible if one or more of the following criteria are satisfied:;* Contraindication to any of the components of the polypill (e.g. known intolerance to aspirin, statins, or ACE inhibitors; pregnancy or likely to become pregnant or breastfeeding women during the treatment period). Such contrindications are fully listed in the Investigator Brochure.
* The treating doctor considers that changing a participant*s cardiovascular medications would put the participant at risk (e.g. symptomatic heart failure, high dose *-blocker required to manage angina or for rate control in atrial fibrillation, accelerated hypertension, severe renal insufficiency, a history of severe resistant hypertension).;* Other potential reasons for exclusion include:
* Known situation where medication regimen might be altered for a significant length of time, e.g. current acute cardiovascular event, planned coronary bypass graft operation.
* Unlikely to complete the trial (e.g. life-threatening condition other than cardiovascular disease) or adhere to the trial procedures or attend study visits (e.g. major psychiatric condition, dementia).
* Women of child bearing potential should be on a medically accepted form of contraception (oral or implanted contraception, IUD or tubal sterilisation). If there is any possibility of pregnancy, prior to randomisation a blood or urine pregnancy test will be performed. Final decisions about eligibility will be made at the discretion of the trial Investigator and potential trial participant, in light of any additional requirements or guidance from local ethics committees and other regulatory bodies.
* Night shift workers.
