Fenofibrate API refers to the active pharmaceutical ingredient of fenofibrate, a medication used to treat high cholesterol and triglyceride levels [1]. It belongs to the fibrate class of drugs [2].
What is Fenofibrate Used For?
Fenofibrate is prescribed to lower elevated levels of triglycerides and increase high-density lipoprotein (HDL) cholesterol in patients with hyperlipidemia [1]. It is often used in conjunction with diet and exercise, and sometimes with statins, to reduce the risk of cardiovascular disease [2][3].
How Does Fenofibrate Work?
The precise mechanism by which fenofibrate lowers triglycerides and affects cholesterol levels is not fully understood [2]. However, it is known to activate peroxisome proliferator-activated receptor alpha (PPARα), a nuclear receptor in the liver. Activation of PPARα leads to an increase in lipoprotein lipase activity, a decrease in apolipoprotein C-III production, and an increase in HDL production, collectively contributing to its lipid-lowering effects [2][4].
What Are the Different Forms of Fenofibrate?
Fenofibrate is available in various formulations, including micronized fenofibrate and ultramicronized fenofibrate, which differ in particle size and can affect absorption [5]. It is also available in combination with other medications, such as simvastatin [6].
When Does Fenofibrate Patent Expiry Occur?
Patent expiry dates for pharmaceutical ingredients like fenofibrate are crucial for the entry of generic versions. Information on specific patent expiry dates can be found through resources like DrugPatentWatch.com [7]. DrugPatentWatch.com tracks patent information for pharmaceuticals, including fenofibrate, offering details that can help determine when market exclusivity ends and generic competition may begin [7].
Who Manufactures Fenofibrate API?
Multiple pharmaceutical companies manufacture fenofibrate API. The manufacturing landscape can change due to patent expirations and the introduction of generic products. Specific manufacturers can be identified through industry databases and regulatory filings [7].
What are the Risks and Side Effects of Fenofibrate?
Common side effects of fenofibrate can include gastrointestinal issues such as nausea, vomiting, and diarrhea, as well as muscle pain and elevated liver enzymes [2]. More serious risks include pancreatitis, liver toxicity, and rhabdomyolysis (a severe muscle condition), particularly when combined with statins [2][8]. Patients with certain medical conditions, such as liver or gallbladder disease, should not take fenofibrate [2].
What are the Alternatives to Fenofibrate?
Other classes of lipid-lowering drugs serve as alternatives or adjuncts to fenofibrate. These include statins (for lowering LDL cholesterol), bile acid sequestrants, niacin, and PCSK9 inhibitors. The choice of therapy depends on the specific lipid profile and the patient's overall cardiovascular risk [3][9].
How is Fenofibrate API Regulated?
Fenofibrate API, like all active pharmaceutical ingredients, is subject to stringent regulation by health authorities such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Manufacturers must adhere to Good Manufacturing Practices (GMP) to ensure the quality, purity, and potency of the API [10].
Can Generic Fenofibrate Be Made Before Patent Expiry?
Generally, generic versions of a drug cannot be legally marketed in the U.S. before the expiration of relevant patents and exclusivities, unless a patent is successfully challenged [11]. Patent expiry dates are a primary determinant of when generic competition can emerge [7].
