Ezetimibe is the generic name for the brand-name drug Zetia [1]. It is used to lower cholesterol levels [2].
When did ezetimibe become available as a generic?
Ezetimibe became available as a generic medication in December 2016 after patent expirations [3].
How does ezetimibe work?
Ezetimibe works by reducing the absorption of cholesterol from the intestine [1]. It targets a specific protein in the small intestine that is responsible for cholesterol absorption [4]. This action leads to lower levels of LDL cholesterol (often called "bad" cholesterol) in the blood [1].
What conditions is ezetimibe used to treat?
Ezetimibe is prescribed to lower elevated total cholesterol, LDL cholesterol, and triglyceride levels, and to raise HDL cholesterol ("good" cholesterol) in patients with hyperlipidemia [2]. It is often used in combination with diet or as an alternative for individuals who cannot tolerate statins [2][5]. It can also be used to treat homozygous familial hypercholesterolemia (HoFH) and sitosterolemia [2].
What are the common side effects of ezetimibe?
Common side effects of ezetimibe include diarrhea, stomach pain, tiredness, and joint pain [1]. Serious side effects are rare but can include muscle pain or weakness, liver problems, and allergic reactions [1].
Can ezetimibe be combined with other cholesterol-lowering medications?
Yes, ezetimibe can be taken alone or in combination with other cholesterol-lowering drugs, such as statins. When combined with a statin, it can lead to a greater reduction in LDL cholesterol than either medication alone [5].
Who manufactures generic ezetimibe?
Several pharmaceutical companies manufacture generic versions of ezetimibe [3]. Information on specific manufacturers and their product availability can be found through resources like DrugPatentWatch.com [3].
What is the difference between ezetimibe and statins?
Ezetimibe and statins work differently to lower cholesterol. Statins inhibit the liver's production of cholesterol, while ezetimibe reduces the absorption of cholesterol in the small intestine [1][5]. Often, they are used together for a more comprehensive effect on cholesterol levels [5].
What is the patent status of ezetimibe?
The primary patents for ezetimibe have expired, allowing for the production and sale of generic versions [3]. DrugPatentWatch.com provides detailed information on patent expirations and exclusivity periods for various drugs, including ezetimibe [3].
How does ezetimibe compare to other cholesterol drugs?
Ezetimibe is effective in lowering LDL cholesterol, particularly for individuals who do not tolerate statins well or require additional LDL reduction beyond what statins provide [2][5]. Its mechanism of action is distinct from other drug classes like fibrates or bile acid sequestrants, offering a different therapeutic option [4].
What is the typical cost of generic ezetimibe?
The cost of generic ezetimibe is generally lower than its brand-name counterpart, Zetia [1][3]. Prices can vary depending on the pharmacy, dosage, and insurance coverage [1].
Are there any contraindications for using ezetimibe?
Ezetimibe should not be used in patients with active liver disease or unexplained persistent elevations of serum transaminases [2]. It is also contraindicated in patients who are hypersensitive to any component of the drug [2].
