Key takeaways
Pravastatin and Lipitor (atorvastatin) are statins used to treat high cholesterol, working by inhibiting the HMG-CoA reductase enzyme in the liver to decrease cholesterol production.
Pravastatin is not extensively metabolized by the liver’s CYP3A4 enzyme and is usually taken in the evening, whereas Lipitor is heavily processed by this enzyme and can be taken at any time of the day.
Both medications are effective in reducing the risk of heart attacks and strokes, with their efficacy depending on the patient’s overall condition and other factors, without a clear winner in terms of effectiveness.
Pravastatin and Lipitor interact with similar medications, but Lipitor’s metabolism by the CYP3A4 enzyme means it may have more potential drug interactions.

Pravastatin and Lipitor (atorvastatin) are prescription medications used to treat high cholesterol. Cholesterol levels that are higher than normal can increase the risk of heart disease, vascular disease, heart attacks, and strokes. Cholesterol is primarily produced in the liver through the HMG‐CoA reductase enzyme.
Pravastatin and atorvastatin are drugs that are classified as HMG-CoA reductase inhibitors. Also known as statin drugs, pravastatin and atorvastatin inhibit, or block, the HMG-CoA reductase enzyme, which leads to decreased cholesterol production in the liver. The use of statins also increases the amount of LDL (low-density lipoprotein) receptors in the liver, which helps lower levels of LDL, or the bad type of cholesterol, in the blood.
Both pravastatin and atorvastatin work in similar ways, but they have some differences to be aware of.
What are the main differences between pravastatin and Lipitor?
Pravastatin is the generic name for Pravachol. Unlike other statin drugs, pravastatin is not extensively metabolized, or processed, by CYP3A4 enzymes in the liver. Instead, pravastatin is broken down in the stomach.
Pravastatin generic tablets are available in strengths of 10 mg, 20 mg, 40 mg, and 80 mg. Pravastatin is usually prescribed to be taken once daily in the evening. It has been shown that pravastatin is more effective when taken in the evening rather than in the morning.
Lipitor is a brand-name medication and is available in a generic version called atorvastatin. Unlike pravastatin, atorvastatin is heavily processed by the CYP3A4 enzyme in the liver. Therefore, atorvastatin may potentially interact with more medications than pravastatin.
Lipitor is available in oral tablets with strengths of 10 mg, 20 mg, 40 mg, and 80 mg. Lipitor can be taken in the morning or evening, and it is usually taken once daily.

Conditions treated by pravastatin and Lipitor
Pravastatin and atorvastatin can help reduce the risk of heart attacks and strokes in people with coronary heart disease. Both medications can also help reduce the risk of death from heart disease. Risk factors for heart disease include high blood pressure, smoking, and high cholesterol levels.
Both pravastatin and atorvastatin are FDA approved to reduce elevated total-cholesterol and LDL levels (also known as hyperlipidemia or hypercholesterolemia). Statin medications can also help treat elevated levels of triglycerides, which are another type of fats or lipids in the body. Someone with elevated levels of triglycerides has hypertriglyceridemia.
Pravastatin and Lipitor can also increase HDL levels in the blood. HDL cholesterol is what is known as the “good” cholesterol in the blood.
| Condition | Pravastatin | Lipitor |
| Hyperlipidemia | Yes | Yes |
| Hypercholesterolemia | Yes | Yes |
| Hypertriglyceridemia | Yes | Yes |
Is pravastatin or Lipitor more effective?
Both pravastatin and atorvastatin are effective medications for treating high blood cholesterol. The more effective drug depends on your overall condition, the severity of your condition, other drugs you might be taking, and other factors.
One comparative study found that there is no significant difference between pravastatin, simvastatin, and atorvastatin for preventing cardiovascular events. In other words, these statin drugs were similarly effective for reducing heart attacks and coronary heart disease.
A systematic review that pooled over 90 clinical trials compared statin drugs such as fluvastatin, atorvastatin, pravastatin, simvastatin, and rosuvastatin. The review concluded that atorvastatin, fluvastatin, and simvastatin had the highest probability of being the best treatment for preventing cardiovascular events.
Consult a healthcare provider to determine the best statin drug for you. After conducting a blood test and evaluating your overall condition, a provider will be able to determine whether pravastatin or atorvastatin is a more effective drug for you. They might also prescribe a different statin drug such as Zocor (simvastatin) or Crestor (rosuvastatin).

Drug interactions of pravastatin vs. Lipitor
Pravastatin and atorvastatin interact with similar medications. However, since atorvastatin is metabolized primarily by the CYP3A4 enzyme in the liver, it may interact with more drugs that affect the CYP3A4 enzymes in the liver.
Taking medications like cyclosporine, clarithromycin, or ritonavir with either pravastatin or atorvastatin can lead to increased statin levels in the blood, which can increase the risk of adverse effects.
Antacids can interfere with the absorption of statin medications and reduce their effectiveness. The administration of antacids and statins should be separated by at least two hours. Cholestyramine can also decrease the absorption and effectiveness of statins. The administration of cholestyramine and statins should be separated by four hours.
Niacin and fibrates can increase the risk of myopathy and rhabdomyolysis when taken with either pravastatin or atorvastatin.
The use of atorvastatin should be avoided or monitored while consuming grapefruit juice. Grapefruit juice acts as a CYP3A4 inhibitor that can lead to increased levels of atorvastatin in the blood and increase the risk of side effects.
