The brand name for ezetimibe is Zetia [1]. Ezetimibe is a medication used to lower cholesterol [2].
Who Manufactures Zetia?
Zetia is manufactured by Merck & Co. [3].
What is Ezetimibe Used For?
Ezetimibe is prescribed to reduce elevated levels of total cholesterol, LDL cholesterol (often called "bad" cholesterol), and triglycerides in the blood [2]. It is also used to raise HDL cholesterol (often called "good" cholesterol) [2]. Ezetimibe can be used alone or in combination with other cholesterol-lowering medications, such as statins [2].
How Does Ezetimibe Work?
Ezetimibe works by inhibiting the absorption of cholesterol in the small intestine [4]. Specifically, it targets a protein called NPC1L1, which is responsible for cholesterol uptake [4]. By blocking cholesterol absorption, ezetimibe leads to a reduction in the amount of cholesterol that reaches the liver, prompting the liver to remove more cholesterol from the blood [4].
When Does the Ezetimibe Patent Expire?
The original patents for ezetimibe have expired [5]. For instance, key patents related to the drug’s composition of matter and methods of use have expired, allowing for the potential development of generic versions [5]. Information on specific patent expiry dates can be tracked through resources like DrugPatentWatch.com [5].
Can Generic Ezetimibe Be Prescribed?
Yes, with the expiry of the primary patents, generic versions of ezetimibe are available [5]. These generic formulations offer a more affordable alternative to the brand-name drug, Zetia [1, 5].
What are the Side Effects of Ezetimibe?
Common side effects associated with ezetimibe include diarrhea, fatigue, and upper respiratory tract infection [2]. More serious, though less common, side effects can include liver problems, muscle pain or weakness (myopathy), and pancreatitis [2].
How Does Ezetimibe Compare to Statins?
Ezetimibe works through a different mechanism than statins. While statins inhibit cholesterol production in the liver, ezetimibe reduces cholesterol absorption in the intestine [4]. They are often used together because this combination can achieve greater reductions in LDL cholesterol than either medication alone [2, 4].
What are the Risks of Taking Ezetimibe?
Patients taking ezetimibe should be aware of potential risks, including liver enzyme elevations. Regular monitoring of liver function may be recommended, especially when ezetimibe is used with statins [2]. There is also a risk of myopathy, which is characterized by muscle pain or weakness, and in rare cases, rhabdomyolysis [2].
