Crestor vs Lipitor
Introduction
For patients with high cholesterol levels or other cardiovascular conditions, certain drugs that inhibit the body's production of cholesterol can help in managing these health concerns. Crestor and Lipitor are two such drugs that are widely prescribed for controlling elevated cholesterol levels. They each impact different aspects of lipid metabolism but both have substantial effects on lowering low-density lipoprotein (LDL), also known as "bad" cholesterol, in patients with hyperlipidemia. Crestor, generically known as rosuvastatin, belongs to a group of drugs called HMG-CoA reductase inhibitors or statins which reduces levels of "bad" cholesterol and triglycerides while raising "good" cholesterol (HDL) in the blood. Lipitor, on the other hand, is another statin drug whose generic name is atorvastatin; it works similarly by reducing LDL and triglycerides while boosting HDL.
What is Crestor?
Rosuvastatin (the generic name for Crestor) and Atorvastatin (the generic name for Lipitor) are both part of the statin class of cholesterol-lowering drugs, a significant advancement from the first generation bile acid sequestrants. Both were approved by the FDA, with Atorvastatin getting approval in 1996 and Rosuvastatin in 2003. These medications work by inhibiting an enzyme called HMG-CoA reductase involved in cholesterol production, effectively reducing its level in the bloodstream. They are prescribed to manage high levels of LDL ("bad") cholesterol and increase HDL ("good") cholesterol. Between these two, Rosuvastatin is more potent milligram-for-milligram compared to Atorvastatin which means lower doses can be used to achieve similar therapeutic effects. This results in fewer side effects than other statins that require higher dosages.
What conditions is Crestor approved to treat?
Crestor (rosuvastatin) is approved for the treatment of several lipid disorders, including:
- Primary hyperlipidemia and mixed dyslipidemia as an adjunct to diet
- Hypertriglyceridemia
- Adult patients with hypercholesterolemia
- Pediatric patients known to have heterozygous familial hypercholesterolemia
- Prevention of cardiovascular diseases
How does Crestor help with these illnesses?
Crestor aids in managing high cholesterol levels by blocking an enzyme called HMG-CoA reductase, which is instrumental in the liver's cholesterol production. By inhibiting this enzyme, Crestor reduces the amount of cholesterol produced within the body. Cholesterol plays a key role in many physiological processes but can become harmful when present at excessive levels leading to cardiovascular diseases such as heart attacks and strokes. It is believed that individuals with high cholesterol produce too much of it for their bodies to effectively process and remove from the bloodstream. Therefore, by reducing cholesterol production, Crestor can limit potential health risks associated with high LDL (low-density lipoprotein) levels or 'bad' cholesterol and help patients manage their condition more effectively.
What is Lipitor?
Lipitor, also known by its generic name atorvastatin, is a statin medication that works to decrease the production of cholesterol in the liver. This helps prevent heart disease and stroke by reducing the risk of plaque build-up in arteries. Lipitor was first approved by the FDA in 1996 and has since become one of the most widely prescribed medications for high cholesterol. Unlike Crestor (rosuvastatin), Lipitor does not significantly increase levels of HDL ("good") cholesterol but it does efficiently lower LDL ("bad") cholesterol and triglycerides. Its side-effect profile differs from Crestor's as well; while both drugs can cause muscle pain, only Lipitor has been linked with a slight increase in blood sugar levels which could lead to type 2 diabetes - although this risk is relatively low. The effectiveness on lipid profiles makes Lipitor an excellent choice for patients requiring substantial reductions in their LDL cholesterol levels.
What conditions is Lipitor approved to treat?
Lipitor, also known as atorvastatin, has been approved by the FDA for the treatment of:
- High cholesterol and triglycerides
- Prevention of cardiovascular disease in adults who are at a high risk
- Secondary prevention of heart attack and stroke in patients with existing heart disease.
How does Lipitor help with these illnesses?
Lipitor, also known as atorvastatin, is a drug that plays roles in many processes within the body by inhibiting the enzyme HMG-CoA reductase. This enzyme is heavily involved in the production of cholesterol within the liver. By blocking its action, Lipitor effectively reduces levels of low-density lipoprotein (LDL), or "bad" cholesterol and triglycerides while increasing levels of high-density lipoprotein (HDL), or "good" cholesterol. Compared to Crestor, another statin medication used to manage cholesterol levels, Lipitor has been around for a longer period and thus has an extensive track record regarding its efficacy and safety profile. Therefore it might be prescribed when a patient does not respond well to newer generation statins like Crestor or may even be combined with other lipid-lowering therapies if necessary.
How effective are both Crestor and Lipitor?
Both rosuvastatin (Crestor) and atorvastatin (Lipitor) are high-intensity statins with established histories of efficacy in managing high cholesterol levels and reducing the risk of cardiovascular events. They received FDA approval within a few years of each other: Lipitor in 1996, and Crestor in 2003.
In terms of their effectiveness, both drugs have shown similar capabilities to lower LDL cholesterol levels. A direct comparison study conducted between these two medications found that they had comparable effects on LDL reduction over six weeks; however, it was observed that rosuvastatin could potentially provide slightly better outcomes when used at maximum doses.
A meta-analysis performed in 2010 examined the safety profiles of both Crestor and Lipitor. The report concluded that there were no significant differences between the two drugs regarding adverse effects such as muscle pain or liver enzyme abnormalities. Both drugs exhibited favorable safety profiles compared to many other statins available on the market.
However, despite their similarities, there are some differentiating factors associated with these two medicines. For instance, while atorvastatin is metabolized by cytochrome P450 enzymes - which can lead to drug interactions if taken concurrently with certain other medications – Rosuvastatin does not share this characteristic and may be less likely to cause such interactions.
While Atorvastatin holds its place as one among the most widely prescribed cholesterol-lowering medications worldwide due to its proven efficacy and tolerability across diverse patient populations for more than twenty years now including elderly patients above 65 years old with or without renal impairment.
On another note,a review from 2015 indicated that Crestor appears slightly more potent than Lipitor when used at maximum dosages making it an effective choice for patients who need aggressive lipid lowering therapy . However like all medication choices ,the ultimate decision should take into consideration patient tolerance ,cost considerations as well as physician preference .
Regardless both remain first-line treatment options for hypercholesterolemia providing physicians multiple options depending upon clinical scenario,baseline LDL cholesterol level,potential drug-drug interaction concerns,tolerance issues,cost constraints etc..
At what dose is Crestor typically prescribed?
Oral dosages of Crestor range from 5-40 mg/day, but studies have shown that a starting dose of 10-20 mg/day is usually adequate for most adults in lowering their high cholesterol. Children aged 8 to 17 may be started on 5-10 mg/day. For both populations, the dosage can be adjusted after several weeks if there is no adequate response. The maximum dosage of Crestor that should not be exceeded in any case is 40 mg/day.

At what dose is Lipitor typically prescribed?
Lipitor treatment is typically initiated at a dosage of 10–20 mg/day, taken once daily. This dose can be adjusted up to 40 mg per day after several weeks if cholesterol levels have not adequately decreased. The maximum recommended dose is 80 mg/day and this should only be considered when there has been no adequate response to lower doses and the benefits outweigh the potential risks. As with all medications, adjustments in dosages should be made under careful monitoring by your healthcare provider.

- Kidney issues manifested through little to no urinating and swelling in your ankles or feet
- Cognitive issues including memory loss or confusion If you experience any unusual changes in mood while taking Lipitor, reach out to your healthcare provider promptly.
Contraindications for Crestor and Lipitor?
Both Crestor and Lipitor, like most other cholesterol-lowering medications, may cause muscle pain or weakness in some patients. If you notice severe muscle pain, tenderness or weakness, particularly if accompanied by fever or unexplained tiredness, please seek immediate medical attention.
Neither Crestor nor Lipitor should be taken if you have active liver disease or are pregnant or breastfeeding. Always inform your physician of any medication you're currently taking; certain drugs can interact with these statins to increase the risk of serious muscle problems.
Regular monitoring of liver function tests is required while on either drug due to the potential for increased liver enzymes and rare cases of liver failure associated with statin use. It's also important that grapefruit juice is avoided as it can significantly increase blood levels of both Crestor and Lipitor leading to an increased risk for side effects.
Always consult a healthcare professional before starting a new medication regimen including over-the-counter medicines and supplements.
How much do Crestor and Lipitor cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Crestor (10 mg) averages around $200, which works out to approximately $6.67/day.
- The price of 30 tablets of Lipitor (20 mg) averages around $127, working out to roughly $4.23/day.
Thus, if you are in the higher dosage range for Crestor (i.e., 40 mg/day), then brand-name Lipitor is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which drug is right for you.
In terms of their generic counterparts, rosuvastatin and atorvastatin:
- Rosuvastatin is available in packs ranging from 15 up to several hundred tablets with an average cost between $0.50 and $2 per day depending on your dose.
- Atorvastatin can be found in similar quantities with costs starting as low as about $.11/day up to about $.75/day depending on quantity purchased and daily dosage requirements.
As always, it's important to understand that while cheaper alternatives may be available, effectiveness can vary based on individual patient factors like health history and specific condition being treated.
Popularity of Crestor and Lipitor
Rosuvastatin, also known by its brand name Crestor, was estimated to have been prescribed to about 21 million people in the US in 2019. This statin accounted for approximately 23% of all prescriptions within this class of cholesterol-lowering drugs. Rosuvastatin has generally increased in prevalence since it was approved by the FDA in 2003.
Atorvastatin, better recognized as Lipitor, is another popular statin that had around 94 million prescriptions filled in the USA during 2019. It accounts for just under half of all statin prescriptions and a substantial portion of overall cardiovascular medication use. The high prescription rate for atorvastatin could be partially attributed to its introduction earlier than rosuvastatin (1996 compared with 2003), giving it a head start on market share. Despite facing competition from other newer drugs like rosuvastatin, atorvastatin's usage remains robust even after more than two decades on the market.
Conclusion
Both Crestor (rosuvastatin) and Lipitor (atorvastatin) have well-established records of usage in patients with high cholesterol levels, and are backed by numerous clinical trials demonstrating their effectiveness over placebo treatments. There may be instances where these drugs could be used together, but this requires careful consideration by a physician due to potential drug interactions. Both drugs work as statins, which reduce the body's cholesterol production; however, they differ slightly in potency and how long their effects last. Crestor is considered more potent than Lipitor and it also maintains its action longer.
Both medications are available in generic form representing substantial cost savings for patients who must pay out of pocket. It's important to note that both Crestor and Lipitor might take a few weeks before noticeable effects on your cholesterol levels can be seen.
The side effect profile is similar between both drugs - generally well-tolerated but with some people experiencing digestive problems or muscle pain. Patients should immediately seek medical help if unusual symptoms occur such as unexplained muscle weakness or pain, especially if accompanied with fever or feeling ill.
