What is the mechanism of action of statins?

Christopher Duran |
Mechanism of Action Statins work by competitively blocking the active site of the first and key rate-limiting enzyme in the mevalonate pathway, HMG-CoA reductase. Inhibition of this site prevents substrate access, thereby blocking the conversion of HMG-CoA to mevalonic acid.

Likewise, what is the mechanism of action for atorvastatin?

Mechanism of Action Atorvastatin competitively inhibits 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. By preventing the conversion of HMG-CoA to mevalonate, statin medications decrease cholesterol production in the liver.

Also Know, what do statins inhibit? Statins inhibit an enzyme called HMG-CoA reductase, which controls cholesterol production in the liver. The medicine blocks the enzyme, thereby slowing down the cholesterol production process.

In this manner, how do statins work in the body?

Statins, and How Statins Work Statins have been clearly shown to reduce blood cholesterol and prevent atherosclerosis, or heart disease. They work by reducing the liver's production of cholesterol. They block an enzyme called HMG CoA Reductase that the liver uses to make cholesterol.

What is in a statin drug?

"Statins" is a class of drugs that lowers the level of cholesterol in the blood by reducing the production of cholesterol by the liver. (The other source of cholesterol in the blood is dietary cholesterol.) Statins block the enzyme in the liver that is responsible for making cholesterol.

Does lipitor cause hair loss?

Atorvastatin (Lipitor) and simvastatin (Zocor) belong to a group of cholesterol-lowering medications known as “statins”. Have hair loss is a reported side effect of both drugs. The newer statin, rosuvastatin (Crestor), luckily does not have this risk.

What is the classification of atorvastatin?

Atorvastatin is in a class of medications called HMG-CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.

What are the most common side effects of atorvastatin?

Commonly reported side effects of atorvastatin include: hemorrhagic stroke, arthralgia, diarrhea, and nasopharyngitis. Other side effects include: urinary tract infection, insomnia, limb pain, muscle spasm, musculoskeletal pain, myalgia, and nausea.

Atorvastatin should be used as an adjunct to other lipid-lowering treatments (e.g. LDL apheresis) in these patients or if such treatments are unavailable.

Which statin has the least amount of side effects?

In the analysis of 135 previous studies, which included nearly 250,000 people combined, researchers found that the drugs simvastatin (Zocor) and pravastatin (Pravachol) had the fewest side effects in this class of medications. They also found that lower doses produced fewer side effects in general.

What are the side effects of atorvastatin 20 mg?

Do statins clear the arteries of plaque?

Statins May Reverse Plaque Buildup. March 13, 2006 (Atlanta) -- For the first time, a popular cholesterol-lowering statin drug has been shown to actually clear plaque out of fat-clogged heart arteries.

What foods should be avoided when taking statins?
