In combination with statin drugs, fibrates cause an increased risk of rhabdomyolysis,...
What are fibrates used to treat?
Fibrates are cholesterol-lowering medicines. They work by decreasing your triglycerides, a type of fat in your blood. Fibrates can also increase your levels of high-density lipoprotein (HDL) cholesterol. If you have high triglycerides, taking fibrates may decrease your risk of heart disease, heart attack and stroke.
Are fibrates safe to take with statins?
In combination with statin drugs, fibrates cause an increased risk of rhabdomyolysis, idiosyncratic destruction of muscle tissue, leading to renal failure. The less lipophilic statins are less prone to cause this reaction, and are probably safer when combined with fibrates. Drug toxicity includes acute kidney injury.
Are fibrates safer than statins?
Are fibrates safer than statins? Both fibrates and statins are safe medications. Statins are established to reduce the risk for cardiovascular disease, but this has not been consistently proven for fibrate medications. Fibrates may be mainly given to reduce the risk of pancreatitis.
How dangerous is fenofibrate?
Severe allergic reaction warning Fenofibrate can cause severe allergic reactions. These can include anaphylaxis and angioedema (swelling), and can be life-threatening. Some reactions can occur days or weeks after starting this drug.
What is the safest high cholesterol medication?
Fortunately, most side effects are mild and disappear promptly when the statin is stopped. In some cases, the problems will resolve simply by reducing the dose or switching to another statin, but care is required. Still, all in all, the statins are the safest and best tolerated of all cholesterol-lowering medications.
Why statins are better than fibrates?
In summary, statins and fibrates work by different mechanisms. Statins have greater benefit than fibrates in decreasing heart attacks and strokes. Fibrates, though, may be appropriate for people with elevated triglyceride levels.

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.
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.

Do fibrates reduce TG?
Consequently, fibrates reduce TG by up to 50% and increase HDL-C by up to 20%, ...
Can fibrates be used with statins?
Fibrates are used in accessory therapy in many forms of hypercholesterolemia, but are absolutely contraindicated in combination with statins due to an increased risk of rhabdomyolysis. These stimulate peroxisome proliferator activated receptor (PPAR) alpha, which controls the expression of gene products that mediate the metabolism of TG and HDL. As a result, synthesis of fatty acids, TG and VLDL is reduced, whilst that of lipoprotein lipase, which catabolises TG, is enhanced. In addition, production of Apo A1 and ATP binding cassette A1 is up-regulated, leading to increased reverse cholesterol transport via HDL. Consequently, fibrates reduce TG by up to 50% and increase HDL-C by up to 20%, but LDL-C changes are variable. Fewer large-scale trials have been conducted with fibrates than with statins and the results are less conclusive, but reduced rates of cardiovascular disease have been reported with fibrate therapy in the subgroup of patients with low HDL-C levels and elevated TG (e.g. TG > 2.3 mmol/L (200 mg/dL)). Fibrates are usually well tolerated but share a similar side-effect profile to statins. In addition, they may increase the risk of cholelithiasis and prolong the action of anticoagulants. Accumulating evidence suggests that they may also have a protective effect against diabetic microvascular complications.
Does fenofibrate lower HDL?
They are therefore used in many hyperlipidemias. Due to a rare paradoxical decrease in HDL-C seen in some patients on fenofibrate, as per US FDA label change, it is recommended that the HDL-C levels be checked within the first few months after initiation of fibrate therapy. If a severely depressed HDL-C level is detected, fibrate therapy should be withdrawn, and the HDL-C level monitored until it has returned to baseline.
Can fibrates cause stomach pain?
Most fibrates can cause mild stomach upset and myopathy (muscle pain with CPK elevations). Fibrates decrease the synthesis of bile acid by down-regulation of cholesterol 7 alpha-hydroxylase and sterol 27-hydroxylase expression, therefore making it easier for cholesterol to precipitate and increasing the risk for gallstones .
Do fibrates reduce heart attacks?
Clinical trials do support their use as monotherapy agents. Fibrates reduce the number of non-fatal heart attacks, but do not improve all-cause mortality and are therefore indicated only in those not tolerant to statins.
Can fibrates cause kidney failure?
In combination with statin drugs, fibrates cause an increased risk of rhabdomyolysis, idiosyncratic destruction of muscle tissue, leading to kidney failure. The less lipophilic statins are less prone to cause this reaction, and are probably safer to be combined with fibrates than the more lipophilic statins are.
Why are fibrates used in medicine?
Fibrates are used in the treatment of several metabolic disorders, mainly those associated with dyslipidemia. They are prescribed as second-line drug choice in hypertriglyceridemia when diet change and non-pharmacological measures don’t help, and in people with low HDL-C levels with hypercholesterolemia or dyslipidemia.

What is the mechanism of action of fibrates?
Mechanism of action of fibrates relies on activation of peroxisome proliferator-activated receptor α , known as PPAR-α . Activation of this receptor stimulates the synthesis of lipoprotein lipase, so the breakdown of triglycerides increases, while fibrates reduce the production of apolipoprotein C-III, which is inhibiting lipoprotein lipase ...
When were fibrotes first synthesized?
Fibrates were first synthesized in 1950’ where they’ve expressed their hypocholesterolemic effects. The first used drug of this class, called clofibrate was founded in 1962 by Thorp and Waring and it was approved for the treatment of hyperlipidemias in 1967 in the United States. The true mechanism of its action was not known for many years ...
Can statins cause rhabdomyolysis?
Statins are most commonly used hypolipemic drugs, used to treat hypercholesterolemia. If they’re used at the same time as fibrates, a chance for rhabdomyolysis increases, as fibrates (especially gemfibrozil) can interfere with the elimination of statins.
Do fibrates interact with other drugs?
Fibrates can come in interaction with other drugs, so it’s important to tell your doctor or your pharmacist which drugs are you using. Some of the important interactions include the ones between fibrates and:
Is HDL-C good or bad?
Low HDL-C levels. High-density lipoprotein cholesterol, known as good cholesterol is important in protection from atherosclerosis, as it removes the LDL-C (low -d ensity lipoprotein cholesterol), the bad cholesterol from arterial walls.
