Therapeutic Indications

Atorvastatin belongs to a collection of drugs, named as HMG CoA reductase inhibitors. These drugs are popularly called “Statins”. Atorvastatin is well-known and available under the brand name Lipitor. Atorvastatin assists in the reduction of low-density lipoprotein, which is nick-named as “bad” cholesterol.

This drug achieves the purpose by boosting the capacity of the body to throw out bad cholesterol through the liver and triglycerides in the blood. This statin works by elevating levels of high-density lipoprotein, or HDL, nick-named as “good” cholesterol. Atorvastatin could form part of combination therapy with other medicines.  It is used in combination with exercise, diet and lifestyle changes to have the maximum effect

Brand Name: LIPITOR®

LIPITOR Tablets to be taken orally with the strengths 10, 20, 40 or 80 mg of atorvastatin contains the following ingredients.

  • Magnesium stearate

Mechanism of Action (MOA)

LIPITOR works as a synthetic lipid- reducing agent. Atorvastatin is an HMG-CoA Reductase Inhibitor. This inhibits hepatic hydroxymethyl-glutaryl-coenzyme A (HMG-CoA) reductase, the enzyme that is in-charge of catalyzing the conversion of HMG-CoA to mevalonate. This is a significant step in the synthesis of cholesterol.

Further, Atorvastatin works to improve the number of LDL receptors on hepatic cell surfaces to boost the catabolism of LDL. Also, helps to lower LDL production and  LDL particles. This agent helps to reduce lipoprotein levels and plasma cholesterol while also regulating immune responses. (NCI04)

This drug works to reduce levels of serum LDL cholesterol and triglycerides as well as Apolipoprotein B. It also works to increase levels of HDL cholesterol which aids in the effective treatment of Hyperlipidemias. These improvements in cholesterol levels help to stave off risks of cardiovascular disease, especially in those who portray risk factors of cardiovascular disease
