Introduction: What is Ezetimibe?

Ezetimibe is a medication primarily used to lower cholesterol levels in the blood. It is often prescribed to individuals who have high cholesterol, particularly those who have not achieved their cholesterol goals through diet and exercise alone. Ezetimibe works by reducing the amount of cholesterol absorbed from the diet, thereby helping to lower overall cholesterol levels; cardiovascular risk reduction has been demonstrated when used in combination with statins.

Uses of Ezetimibe

Ezetimibe is approved for several medical uses, including:

• Primary Hyperlipidemia: It is used to treat high cholesterol levels in adults and children aged 10 years and older.
• Homozygous Familial Hypercholesterolemia: Ezetimibe is indicated for patients with this genetic condition that causes extremely high cholesterol levels.
• Смесена дислипидемия: It can be used in combination with statins to treat patients with mixed dyslipidemia, where abnormalities in cholesterol and/or triglyceride levels are present.
• Намаляване на сърдечно-съдовия риск: Ezetimibe, when used in combination with statins, is prescribed to reduce the risk of cardiovascular events in patients with established cardiovascular disease.

Как работи

Ezetimibe works by inhibiting the absorption of cholesterol in the intestines. It targets a specific protein called the Niemann-Pick C1-like 1 (NPC1L1) protein, which is responsible for transporting cholesterol from the gut into the bloodstream. By blocking this protein, Ezetimibe reduces the amount of cholesterol that enters the bloodstream, leading to lower levels of LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol.

Дозировка и приложение

Ezetimibe is typically administered in tablet form. The standard dosage for adults is 10 mg once daily, which can be taken with or without food. For children aged 10 years and older, the dosage is also 10 mg once daily. It is important to follow the prescribing physician's instructions regarding dosage and to not exceed the recommended amount.
