What is Atorvastatin?

It is a prescription lipid-lowering medicine that manages high cholesterol levels and reduces cardiovascular risk. It lowers low-density lipoprotein (LDL) cholesterol and triglycerides while modestly increasing high-density lipoprotein (HDL) cholesterol.

Atorvastatin Class

Classified as a statin, it is also referred to as an HMG-CoA reductase inhibitor. It primarily targets cholesterol synthesis in the liver.

Atorvastatin Classification

Pharmacologically, Atorvastatin is a high-potency synthetic statin. Therapeutically, it is classified as an antihyperlipidaemic and cardiovascular risk-reducing agent.

Atorvastatin Mechanism of Action

The following steps describe the Atorvastatin mechanism of action:

● It is a competitive reversible inhibitor of HMG-CoA reductase, the rate-limiting enzyme in cholesterol synthesis in the liver.

● By blocking this enzyme, intracellular cholesterol synthesis is reduced.

● This decrease in intracellular cholesterol activates hepatic LDL receptor expression.

● These receptors bind circulating LDL particles and internalise them into the liver cells.

● As a result, more LDL cholesterol is removed from the bloodstream and broken down in the liver, leading to lower LDL-cholesterol (bad cholesterol) levels.

Atorvastatin Structure

Atorvastatin is a small molecule with a complex chemical structure designed to bind selectively to HMG-CoA reductase. It is taken orally as Atorvastatin calcium.

Atorvastatin Use

Atorvastatin uses include:

● Treatment of high cholesterol and triglycerides levels

● Treat conditions like mixed dyslipidaemia
