Fenofibrate may also interact with other drugs and may require a change in dose, frequency, or switching to a new therapy.

How do fibrates treat dyslipidemia?

Fibrates target atherogenic dyslipidemia by increasing plasma HDL-C concentrations and decreasing small dense LDL (sdLDL) particles and TGs, thus contributing to dyslipidemia management, particularly in patients with diabetes (DM) or the metabolic syndrome (MetS).

What do fibrates do?

Fibrates are medicines prescribed to help lower high triglyceride levels. Triglycerides are a type of fat in your blood. Fibrates also may help raise your HDL (good) cholesterol. High triglycerides along with low HDL cholesterol increase the risk of heart disease and stroke.

What are the mechanisms of action and adverse effects of the fibric acid derivatives?

Mechanism of action Fibrates reduce hepatic triglyceride levels by inhibiting hepatic extraction of free fatty acids and thus hepatic triglyceride production. These drugs may also lower cholesterol by increasing endothelial lipoprotein lipase activity.

Can fenofibrate cause kidney problems?

Adverse events reported with the use of fenofibrate include mild reversible increases in serum creatinine and blood urea nitrogen levels in subjects with normal kidney function or mild to moderate decreased kidney function, as well as those with end-stage kidney disease requiring transplantation.

What should I monitor on fenofibrate?

According to OBRA, fenofibrate requires regular monitoring of liver tests as well as evaluation of the complete blood count (CBC) prior to and after initiation. Patients with diabetes mellitus are at increased risk for serious muscle toxicity, including myopathy and rhabdomyolysis, when treated with fibrate therapy.

When do you use fibrates?

Which agent to combine with a statin should be determined for individual patients. Niacin may be most appropriate in patients with low HDL-C and high LDL-C levels, whereas a fibrate may be most appropriate in patients at their LDL-C and HDL-C goals but who have elevated triglyceride levels.

Why do fibrates increase LDL?

Patients with severe hypertriglyceridemia frequently have low levels of LDL cholesterol, and treatment with fibrates may raise their LDL cholesterol levels by increasing intravascular lypolysis of very low-density lipoproteins (VLDL) through lipoprotein lipase, with resultant accumulation of newly formed LDL ('beta- ...

When should fibrates be started?

Treatment of severe hypertriglyceridemia (greater than 500 mg per dL) should begin immediately to reduce the risk of pancreatitis. Usually, a fibrate is tried first with therapeutic lifestyle changes.

What is the best treatment for dyslipidemia?

For single-drug therapy, a statin is preferred for the treatment of dyslipidemia.To lower cholesterol and triglycerides, a statin, a cholesterol absorption inhibitor, gemfibrozil, a fibrate, or the vitamin niacin may be used.

What is the most commonly used medication for dyslipidemia?

HMG-CoA reductase inhibitors (or statins) are the most widely used dyslipidemia drugs. They are useful in treating most of the major types of dyslipidemia.

What is a lipoprotein profile?

A lipoprotein profile is a laboratory test which reports total cholesterol, LDL, HDL, and triglycerides. AST and ALT are values that would be found reported from liver function test.

Does fenofibrate reduce LDL?

Fenofibrate inhibits triglyceride synthesis in the liver resulting in a reduction of LDL levels. Gemfibrozil inhibits the peripheral breakdown of lipids, reduces production of triglycerides and LDLs, and increases HDL concentrations. Niacin acts to inhibit the release of free fatty acids from adipose tissue, increases the rate ...

The client will not experience increased appetite and blood pressure as adverse effects of statins. The client will not experience fatigue and mental disorientation as adverse effects of statins.

What is fibrates in medicine?

What are fibrates? Fibric acid derivatives (fibrates) are a class of medication that lowers blood triglyceride levels. Fibrates lower blood triglyceride levels by reducing the liver 's production of VLDL (the triglyceride-carrying particle that circulates in the blood) and by speeding up the removal of triglycerides from the blood.

What are some examples of fibrates?

Examples of fibrates available in the U.S. are gemfibrozil ( Lopid) and fenofibrate ( Tricor, Fibricor ). Side effects, dosing, drug interactions, and pregnancy information should be reviewed prior to taking fibrates.

Does fenofibrate lower LDL?

Fibrates are not effective in lowering LDL cholesterol; however, when a high risk patient (see NCEP recommendations) also has high blood triglyceride or low HDL cholesterol levels, doctors may consider combining a fibrate, such as fenofibrate ( Tricor ), with a statin. Such a combination will not only lower LDL cholesterol but also will lower blood triglycerides and increase HDL cholesterol levels.

Does MedicineNet provide medical advice?

MedicineNet does not provide medical advice, diagnosis or treatment. See additional information.

Is fenofibrate a statin?

However, fenofibrate does not interfere with the breakdown of statins and should be the safer fibrate to use if it is necessary to use a fibrate with a statin. Furthermore, pravastatin (Pravachol) seems to have fewer muscle toxic effects than the other statins when combined with fibrates, but the risk still exists.

Can you take Gemfibrozil with statins?

Doctors generally avoid combining a statin with fibrates because of concern over the higher risk of muscle damage with the combination. Gemfibrozil should not be combined with simvastatin and if combined with lovastatin the dose of lovastatin should not exceed 20 mg daily. However, fenofibrate does not interfere with the breakdown of statins and should be the safer fibrate to use if it is necessary to use a fibrate with a statin. Furthermore, pravastatin (Pravachol) seems to have fewer muscle toxic effects than the other statins when combined with fibrates, but the risk still exists.

Can fibrates cause diarrhea?

The side effects of fibrates include nausea, stomach upset, and sometimes diarrhea. Fibrates can irritate (inflame) the liver. The liver irritation usually is mild and reversible, but it occasionally can be severe enough to require stopping the drug. Fibrates can cause gallstones when used for several years.

What is the fourth guideline?

The fourth guideline consists of information about the epidemiology of dyslipidemia, diagnosis and treatment criteria, lifestyle interventions, drug therapy, and dyslipidemia in specific patient groups. Finally, we present currently available data and the need to develop and validate scales to assess the risk of CVD specific to Koreans and CVD biomarkers appropriate for the Korean population. The level of evidence and strength of recommendations used in the fourth guideline are shown in Table 1. The fourth guideline is available in full text and an abstract form including tables and figures in Korean. This paper is an English summary of the full text. We hope the fourth guidelines for the treatment of dyslipidemia will be useful for health professionals treating dyslipidemia.

Is the article "Lipid and Atherosclerosis" in the Korean Journal of Internal Medicine?

This article is being simultaneously published in Korean Journal of Internal Medicineand Journal of Lipid and Atherosclerosisby the Korean Association of Internal Medicine and the Korean Society of Lipid and Atherosclerosis.

What is the best treatment for dyslipidemia?

Prevention and treatment of dyslipidemia should be considered as an integral part of individual cardiovascular prevention interventions , which should be addressed primarily to those at higher risk who benefit most. To date, statins remain the first-choice therapy, as they have been shown to reduce the risk of major vascular events by lowering low-density lipoprotein cholesterol (LDL-C). However, due to adherence to statin therapy or statin resistance, many patients do not reach LDL-C target levels. Ezetimibe, fibrates, and nicotinic acid represent the second-choice drugs to be used in combination with statins if lipid targets cannot be reached. In addition, anti-PCSK9 drugs (evolocumab and alirocumab) provide an effective solution for patients with familial hypercholesterolemia (FH) and statin intolerance at very high cardiovascular risk. Recently, studies demonstrated the effects of two novel lipid-lowering agents (lomitapide and mipomersen) for the management of homozygous FH by decreasing LDL-C values and reducing cardiovascular events. However, the costs for these new therapies made the cost–effectiveness debate more complicated.

Which statin has the lowest protein binding?

Pravastatin has the lowest protein-binding (around 50%) when compared to other statins (>90%); furthermore, statins have a low half-life (1–4 h), while atorvastatin and rosuvastatin possess the longest terminal half-life (11–20 h) [13].

How much Gemfribozil is in a day?

The Gemfribozil dose range is 900–1200 mg daily. Fibrates have near 100% oral bioavailability, although fenofibrate, in its immediate release form, has only 60% oral bioavailability. Clofibrate and fenofibrate differ from other drugs of the same class since they are given as a prodrug [23].

Is fenofibrate oral or intravenous?

Fibrates have near 100% oral bioavailability, although fenofibrate, in its immediate release form, has only 60% oral bioavailability. Clofibrate and fenofibrate differ from other drugs of the same class since they are given as a prodrug [ 23 ]. Fenofibric acid is the circulating pharmacologically-active moiety in plasma after oral administration of fenofibrate—the ester of fenofibric acid. The absolute bioavailability of fenofibric acid is approximately 81%. Fenofibric acid is primarily conjugated with glucuronic acid and then excreted in urine [ 24 ]. In vivo data on fenofibrate metabolism reported that fenofibric acid does not undergo oxidative metabolism, e.g, by cytochrome (CYP) P450, to a significant extent [ 24 ].

Which statin has the lowest bioavailability?

Statins differ mainly in the degree of metabolism and the number of active and inactive metabolites. All statins have active metabolites so that their activity depends also on the profile of both parent compound and active metabolites. Pravastatin has the lowest protein-binding (around 50%) when compared to other statins (>90%); furthermore, statins have a low half-life (1–4 h), while atorvastatin and rosuvastatin possess the longest terminal half-life (11–20 h) [ 13 ].

How do statins lower cholesterol?

The first is the selective and competitive inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase , an enzyme that limits the conversion speed of HMG-CoA to mevalonic acid, a precursor of sterols, including cholesterol. Inhibition of this enzyme initially leads to a reduction in liver cholesterol, but compensatory mechanisms induce greater expression of both HMG-CoA reductase and LDL receptors ( Figure 1) [ 10 ]. In the latter case, statins therefore act with an indirect mechanism, by increasing receptor-mediated absorption of LDL, hence reducing plasma LDL. Thanks to the higher number of receptors, they also reduce VLDL and IDL, which are LDL precursors: this third mechanism of action further contributes to lowering plasma LDL-C. In particular, atorvastatin and rosuvastatin produce a marked decrease in plasma triglycerides (TG), as they remove larger amounts of VLDL rich in triglycerides [ 11 ]. Statins are structural analogues of the HMG-CoA intermediate, which is formed by HMG-CoA reductase in mevalonate synthesis. Only lovastatin and simvastatin are inactive lattons, which are hydrolysed in vivo into the corresponding active β-hydroxy acid form [ 12 ].

Can plaques cause a thrombus?

In addition, the plaques may detach and form a thrombus, which can cause a sudden stopping of the bloodstream [4]. Depending on where it is located, obstruction of a vessel may cause myocardial infarction, stroke, or intermittent claudication (at the lower limb level) [4].
