What is Lipitor? 

Lipitor, whose active ingredient is atorvastatin, belongs to a class of drugs known as statins. It is used primarily to help reduce cholesterol levels in the blood and help prevent cardiovascular disease. Atorvastatin works by inhibiting an enzyme involved in cholesterol production in the liver. 

Global Name

Atorvastatin is the generic name for Lipitor, which is also available under various other brand names such as Atorva, Lipvas, Lipistad and Sortis. 


What is Lipitor used for? 

Lipitor is prescribed primarily to lower the levels of bad cholesterol (low-density lipoprotein, or LDL) and triglycerides in the blood while increasing levels of good cholesterol (high-density lipoprotein, or HDL). It is used in the management of: 

  • Hypercholesterolemia (high cholesterol) 
  • Hyperlipidemia (high levels of lipids in the blood) 
  • Prevention of cardiovascular diseases 
  • Stroke prevention 

How do you use Lipitor?

  • Adults: Typically, the starting dose is 10-20 mg per day. The dose may be adjusted depending on cholesterol levels and patient response. 
  • Children (10 years and older): Initial dose is usually 10 mg daily. 

Allergies and Contraindications: 
People with a known allergy to atorvastatin should not use Lipitor. Additionally, it should not be used in patients with active liver disease.

Drug and Food/Beverage Interactions

  • Grapefruit and grapefruit juice can interfere with the enzyme for processing Lipitor, leading to increased drug levels in the blood.
