Mechanism for How It Works
HMG-CoA reductase is an enzyme that helps your body make cholesterol. Statins help to block this enzyme, which in turn causes your body to make less cholesterol. When you make less cholesterol, your liver makes more LDL receptors, which attract LDL particles in the blood. This reduces the amount of LDL ("bad") cholesterol in your bloodstream. Lower LDL cholesterol levels also tend to lead to lower levels of triglycerides and higher HDL (“good”) cholesterol levels in the blood. Statins have anti-inflammatory effects on blood vessels which help reduce the formation of fatty plaque on blood vessel walls.
Statins can interact with many medicines. Below are some examples. But, you should talk to your doctor and pharmacist about the specific medicines that you are taking.
- Cyclosporine (eg, Gengraf)
- Erythromycin (eg, Erythrocin)
- Gemfibrozil (eg, Lopid)
- Nefazodone (eg, Serzone)
- Verapamil (eg, Calan)
- Digoxin (eg, Lanoxin)
- Protease inhibitors to treat HIV, such as indinavir (eg, Crixivan), nelfinavir (eg, Viracept), ritonavir (eg, Norvir), saquinavir (eg, Invirase)
Statins can interact with certain foods, herbs, and supplements. Here are examples of potential interactions:
- Grapefruit juice —increases the absorption of most statins, allowing potentially excessive levels to build up in the bloodstream
- Chaparral, comfrey, and coltsfoot—may increase the risk of liver problems
- St. John’s wort—may decrease blood levels of some statins
- Vitamin B3— possibly increases the risk of developing a potentially fatal condition called rhabdomyolysis
- Red yeast rice—contains a mixture of statins and should not be combined with statin drugs
If you would like to take herbs or supplements while taking a statin, check with your doctor first.
Other Potential Concerns
These conditions can affect how your body uses statins:
- Allergy or intolerance to statins or allergies to other substances, including food

- Alcohol abuse
- Liver disease
