What is the best time to take statins?
To answer this question, we need to understand a little bit more about these HMG-CoA reductase inhibitors. At the most fundamental level, statins are medicines used to lower blood cholesterol levels.
Indications of statins include:
Statins are used because of their activity at HMG-CoA reductase; an enzyme involved in cholesterol production.
More specifically, statins inhibit this enzyme – the rate-limiting enzyme in the mevalonate pathway of cholesterol production. Statins are used to reduce levels of harmful LDL (low-density lipoprotein) cholesterol, whilst increasing the numbers of HDL (high-density lipoprotein) cholesterol – so-called “good cholesterol”.
Statins also have, through indirect means, the effect of reducing triglyceride levels – a harmful kind of lipid that is associated with increasing the risk of cardiovascular disease.
Taken together, statins are a highly effective means to reduce cholesterol levels and prevent the risk of serious cardiovascular events, such as myocardial infarction and stroke.
Broadly speaking, yes, statins are reliably safe medicines.
Side effects with statins include:
Rarely, drug-induced hepatitis can occur.
The short answer is – it depends.
It depends on whether the statin is a short or long-acting drug.
Put simply, most cholesterol production occurs at night. That is why patients are routinely counseled to take statins at night; a time when cholesterol production is at its highest and when dietary intake of cholesterol is at its lowest.
Short-acting statins (which have half-lives around 6 hours) are therefore more effective when taken in the evening. These include:
By their very nature, long-acting statins exert effects over a longer period, and so can be taken either in the morning or evening. Long-acting statins tend to have half-lives 3-times longer than short-acting drugs. These include:
Short-acting drugs are frequently reserved for patients with a low risk of CVD, whereas longer-acting statins are more often used for patients with higher risks of CVD.
Again, it depends upon a variety of clinical factors.
Among these factors include:
Clinicians take these kinds of factors into consideration to determine the most optimum treatment for the patient – reducing the risk of long-term cardiovascular disease and the secondary conditions this can cause.
