Fenofibrate is a medication used to lower cholesterol and triglyceride levels in the blood [1]. It belongs to a class of drugs called fibrates [2].
How does fenofibrate work to lower cholesterol?
Fenofibrate works by affecting fat metabolism in the body. It activates peroxisome proliferator-activated receptors (PPARs), particularly PPAR-alpha [3]. Activation of PPAR-alpha leads to an increase in lipoprotein lipase activity, which breaks down triglycerides. It also reduces the production of apolipoprotein C-III, a substance that inhibits lipoprotein lipase, and increases the production of apolipoprotein A-I and A-II, which are components of HDL cholesterol (often referred to as "good" cholesterol) [3][4].
What are the different forms and strengths of fenofibrate tablets?
Fenofibrate is available in various tablet formulations and strengths. Common strengths include 40 mg, 50 mg, 100 mg, 145 mg, 150 mg, and 200 mg [1]. These tablets can be immediate-release or delayed-release [1].
When does the patent for fenofibrate expire?
The original patents for fenofibrate have long expired, allowing for the availability of generic versions. Specific patent expiry dates would have been many years ago, making it a well-established generic medication. Information on specific patent details can be found on DrugPatentWatch.com [5].
Who manufactures fenofibrate and its generic versions?
Numerous pharmaceutical companies manufacture fenofibrate, including both brand-name and generic versions. Major pharmaceutical companies and smaller generic manufacturers produce the drug.
What are the potential side effects of taking fenofibrate?
Common side effects of fenofibrate can include digestive issues such as abdominal pain, diarrhea, nausea, and vomiting. Other potential side effects may involve back pain, headache, and respiratory tract infections. More serious, though less common, side effects can include liver problems, pancreatitis, and muscle pain or weakness (myopathy) [1][2].
How does fenofibrate compare to other cholesterol-lowering medications?
Fenofibrate is primarily used to lower triglycerides and, to a lesser extent, LDL cholesterol, while increasing HDL cholesterol [4]. This differs from statins, which are the primary class of drugs used to lower LDL cholesterol. Fenofibrate is often prescribed when statins alone are not sufficient to manage dyslipidemia, particularly in patients with high triglyceride levels [2][4].
What are the risks associated with fenofibrate use?
There are several risks associated with fenofibrate use. These include liver enzyme elevations, which require monitoring by a healthcare provider. There is also a risk of rhabdomyolysis (severe muscle breakdown), particularly when fenofibrate is used in combination with statins. Gallbladder disease is another potential concern [1][2]. Patients with a history of liver disease, kidney disease, or pancreatitis should use fenofibrate with caution [1].
What clinical data supports the use of fenofibrate?
Clinical trials have demonstrated fenofibrate's efficacy in reducing cardiovascular events in certain patient populations, especially those with dyslipidemia. For instance, the FIELD (Fenofibrate Intervention and Event Lowering in Diabetes) study showed a reduction in major cardiovascular events in patients with type 2 diabetes and dyslipidemia [6]. The ACCORD (Action to Control Cardiovascular Risk in Diabetes) trial also investigated fenofibrate's effects on cardiovascular outcomes in diabetic patients, though its findings were complex and indicated that the combination of fenofibrate and simvastatin did not reduce the rate of major cardiovascular events compared to simvastatin alone in patients with type 2 diabetes and dyslipidemia [7].
What are patient concerns regarding fenofibrate?
Patients often have concerns about the potential side effects of fenofibrate, particularly muscle pain and liver function. Questions may arise about managing these side effects, the duration of treatment, and interactions with other medications, especially statins. Understanding how fenofibrate fits into their overall cholesterol management plan and its impact on their specific health condition is also a common concern [1][2].
