💊 Mechanism & Pharmacology

Simplified explanation

Atorvastatin, commonly known by its brand name Lipitor, plays a vital role in lowering cholesterol levels. It works by inhibiting a crucial enzyme called HMG-CoA reductase. This enzyme is primarily responsible for cholesterol production in the liver. When atorvastatin blocks this enzyme, the liver starts to pull cholesterol from the blood, contributing to lower levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol. As a result, this helps reduce the risk of cardiovascular diseases, including heart attacks and strokes.

Clinical terms

• HMG-CoA reductase inhibitors: A class of drugs, also known as statins, which atorvastatin belongs to, that decrease cholesterol production.
• Hypercholesterolemia: A medical condition characterized by high levels of cholesterol in the blood, often elevated LDL cholesterol.
• Dyslipidemia: An abnormality in lipid levels, which can include high LDL or low high-density lipoprotein (HDL) cholesterol.
• Cardiovascular events: Medical occurrences involving the heart and blood vessels, such as heart attacks or strokes.

📋 Indications & Off-Label Uses in Canada
