Crestor vs Lipitor 2015
Introduction
For patients with high cholesterol or other types of cardiovascular conditions, certain drugs that inhibit the production of cholesterol in the liver can help manage symptoms and reduce risks. Crestor (rosuvastatin) and Lipitor (atorvastatin) are two such statin drugs often prescribed for these conditions. They each impact different enzymatic pathways within the liver but both have lipid-lowering effects in patients with hyperlipidemia. Crestor is known for its potency at lower doses as it inhibits a key enzyme, HMG-CoA reductase, more effectively than most statins. Lipitor, on the other hand, also classified as an HMG-CoA reductase inhibitor, has been around longer and comes in generic form which may make it more cost-effective for some patients while still providing effective management of cholesterol levels.
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, which have marked a significant advancement from earlier classes of cholesterol medications. Both were approved by the FDA; Lipitor in 1996 and Crestor in 2003. These medications work by blocking an enzyme in your liver that your body uses to make cholesterol, thus reducing total cholesterol levels in the body. They are prescribed for treating high blood pressure and preventing heart attacks or strokes. However, their influence on lipid profiles varies: Rosuvastatin tends to be more potent at lowering LDL ("bad") cholesterol while also increasing HDL ("good") cholesterol slightly more than Atorvastatin does. This might result in it having fewer cardiovascular events compared with other statins like Atorvastatin.
What conditions is Crestor approved to treat?
Crestor (Rosuvastatin) has been approved for the treatment of several lipid disorders, including:
- Primary hyperlipidemia and mixed dyslipidemia, conditions characterized by high levels of fats in the blood
- Hypertriglyceridemia, a condition where there is an excessive amount of triglycerides—a type of fat—in the blood
- Homozygous familial hypercholesterolemia (HoFH), a genetic disorder causing extremely high cholesterol levels
- Atherosclerosis, which is plaque build-up in arteries that can lead to heart attacks or strokes.
How does Crestor help with these illnesses?
Crestor (rosuvastatin) helps to manage high cholesterol levels by inhibiting the action of an enzyme in the liver called HMG-CoA reductase. This enzyme is responsible for producing cholesterol, so when its activity is blocked, the amount of cholesterol produced by the liver decreases. Cholesterol is a fat-like substance that can build up in arteries if present in excessive amounts, leading to heart disease and stroke. Therefore, Crestor works to reduce these risks by lowering overall cholesterol levels.
Lipitor (atorvastatin) functions similarly as it also targets and blocks HMG-CoA reductase; however, there may be slight differences in efficacy and side effects between Crestor and Lipitor due to variations in their chemical structure. Both drugs are considered statins – a class of medications widely used for controlling high cholesterol levels – but individual response might vary based on genetics or other factors like diet and lifestyle habits.
What is Lipitor 2015?
Lipitor 2015, also known as atorvastatin, is a statin medication that works by inhibiting the enzyme HMG-CoA reductase. This action decreases the production of cholesterol in the liver, thereby reducing levels of low-density lipoprotein (LDL) or "bad" cholesterol while increasing levels of high-density lipoprotein (HDL) or "good" cholesterol. Atorvastatin was first approved by the FDA in 1996 and has been one of the most prescribed drugs worldwide due to its efficacy in managing elevated cholesterol levels.
Unlike Crestor (rosuvastatin), Lipitor does not inhibit absorption of coenzyme Q10 from dietary sources which means it might be less likely to cause muscle pain - a common side effect associated with statins. Furthermore, some studies suggest that patients taking Lipitor may have lower rates of stroke compared with those on rosuvastatin. However, individual responses can vary widely and choices between these two medications often depend on personal medical history and other factors.
What conditions is Lipitor 2015 approved to treat?
Lipitor, as of 2015, is approved for the treatment of:
- Elevated LDL cholesterol (commonly referred to as "bad" cholesterol)
- Mixed dyslipidemia (abnormal amounts of lipids in the blood)
- Hypertriglyceridemia (high levels of triglycerides in the blood)
It's also used to slow down medical conditions that are caused by high cholesterol.
How does Lipitor 2015 help with these illnesses?
Lipitor, also known as atorvastatin, is a type of statin medication used to lower bad cholesterol levels and reduce risk of heart disease. It works by inhibiting the enzyme HMG-CoA reductase in the liver, thereby reducing the production of low-density lipoprotein (LDL) cholesterol that can build up on artery walls and lead to heart disease. Lipitor 2015 was thoroughly studied for its effectiveness in lowering LDL levels more significantly than other similar medications like Crestor (rosuvastatin). In addition to this primary function, it has potential benefits including decreased inflammation and stability of arterial plaques. Lipitor may be prescribed when diet and exercise alone are insufficient for managing high cholesterol or when a patient experiences side effects from other types of statins such as Crestor.
How effective are both Crestor and Lipitor 2015?
Both rosuvastatin (Crestor) and atorvastatin (Lipitor) have established histories of success in treating patients with high cholesterol, and they were initially approved by the FDA within a few years of each other. Since they act on different enzymes involved in cholesterol synthesis, they may be prescribed under different circumstances. The effectiveness of rosuvastatin and atorvastatin in reducing LDL cholesterol was directly studied in various trials; both drugs exhibited similar efficacy as well as safety profiles.
A 2015 review reported that rosuvastatin is effective from the first week of treatment, has favorable side effect profile over many other statins, and is well-tolerated even among elderly populations. This study reports that it has been widely prescribed around the globe for its potent lipid-lowering capacity. Furthermore, optimal doses are thought to vary between 10-40 mg/day depending on individual patient requirements.
The same year also saw another review indicating that atorvastatin seems to be highly effective compared to placebo in treating hypercholesterolemia and appears equally efficacious when compared with other common statins like simvastatin or pravastatin. Atorvastatin's strength lies not just as a standalone treatment but also when co-prescribed alongside other treatments like ezetimibe for managing familial hypercholesterolemia or preventing cardiovascular diseases.
In sum, both Crestor and Lipitor appear comparably effective as lipid lowering agents while their choice depends largely upon individual patient factors such as tolerance level or comorbidity conditions.
At what dose is Crestor typically prescribed?
Oral dosages of Crestor range from 5-40 mg/day, but studies have indicated that for most people with high cholesterol, a starting dose of 10-20 mg/day is usually considered. The same applies to Lipitor, where the typical starting dosage is between 10–20 mg per day and can go as high as 80mg/day if needed. Children aged ten years or older may be started on a lower dose like 5mg depending on their LDL-C levels. For either population under treatment with these medications, the dosage could be adjusted after several weeks based on response and tolerance. The maximum daily dose should not exceed in any case is 40mg for Crestor and 80mg for Lipitor.

At what dose is Lipitor 2015 typically prescribed?
Lipitor 2015 treatment generally begins with a dosage of 10-20 mg/day, depending on the patient's LDL levels and risk of heart disease and stroke. The dose can then be adjusted every two to four weeks to a maximum dose of 80mg per day, based on response and tolerability. Lipitor should be taken at any time of the day with or without food but it is usually recommended that patients take their pill at the same time each day for best results. It's critical not to exceed the prescribed dosage unless your doctor advises you otherwise, as there may be an increased risk of side effects such as muscle pain or weakness.
What are the most common side effects for Crestor?
Common side effects of Crestor may include:
- Headache

Always consult your doctor if you experience any adverse reactions while taking medication.
Are there any potential serious side effects for Crestor?
While Crestor and Lipitor are both statins used to lower cholesterol levels, they do have potential side effects which may differ. Some of the serious side effects linked with these medications include:
- An allergic reaction: symptoms can include hives, difficulty breathing or swallowing, or swelling of your face, lips, tongue or throat
- Liver problems: signs of this can involve upper stomach pain, loss of appetite; dark urine; jaundice (yellowing of the skin or eyes)
- Unusual muscle weakness accompanied by fever and a general ill feeling
- Blurred vision and/or eye pain
- Elevated blood sugar levels leading to increased thirst or urination
- Memory problems/ confusion
- A build up of acid in your blood (metabolic acidosis): if you feel confused, tiredness along with irregular heartbeats
If any such severe adverse reactions occur while on either Crestor or Lipitor 2015 treatment regimens - it is strongly advised to seek immediate medical attention. It's important to remember that these drugs should be taken strictly as prescribed by a healthcare professional for optimum efficacy and safety.
What are the most common side effects for Lipitor 2015?
Lipitor, also known as Atorvastatin, has its own set of potential side effects that one should be aware of. These may include:
- Mild muscle pain
- Diarrhea or constipation
- Indigestion or stomach discomfort
- Headache or dizziness
- A mild skin rash
- Sleep problems (insomnia) In rare cases, Lipitor can cause more serious complications like a fast heartbeat and tremors. It is important to always monitor how you feel while taking medication and report any changes to your healthcare professional promptly.
Are there any potential serious side effects for Lipitor 2015?
While Lipitor 2015 is generally well-tolerated, some patients may experience serious side effects. These could include:
- Symptoms of an allergic reaction such as hives, difficulty breathing, swelling of your face or throat
- Muscle weakness or pain accompanied by fever and unusual tiredness
- Dark colored urine suggesting kidney problems
- Upper stomach pain indicating potential liver issues; this might be coupled with fatigue, loss of appetite, dark urine coloration and yellowing eyes/skin (jaundice)
- Sudden severe headache with vision changes
- Signs pointing to a stroke like sudden numbness or weakness on one side of the body, slurred speech and balance problems
If you observe any of these symptoms while taking Lipitor 2015, it's crucial to immediately seek medical attention.
Contraindications for Crestor and Lipitor 2015?
Both Crestor and Lipitor, along with most other cholesterol-lowering medications, may cause muscle related side effects in some people. If you notice muscle pain or weakness, particularly if accompanied by a fever or feeling unwell, please seek immediate medical attention.
Neither Crestor nor Lipitor should be taken if you have liver disease or are pregnant. Always inform your healthcare provider of any pre-existing conditions; both drugs can potentially harm the liver and unborn babies. It's also crucial to avoid excessive alcohol intake while on these medications as it could lead to an increase in liver damage.
Additionally, certain other medications such as antifungals, HIV protease inhibitors and others may interact negatively with Crestor and Lipitor due to their effect on the same enzyme system that metabolizes these statins in the body. A thorough review of all current medication is necessary before starting either drug.
If taking cyclosporine (used for rheumatoid arthritis and psoriasis), gemfibrozil (another type of lipid lowering agent) or large quantities of grapefruit juice (more than 1 litre per day), interactions may occur which could potentially increase risk for serious muscular side effects when combined with Crestor or Lipitor.
How much do Crestor and Lipitor 2015 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 about $6.67/day.
- The price for a supply of 30 Lipitor tablets (10mg) averages close to $220, working out to approximately $7.33/day.
Thus, if you are taking similar dosages for each drug, then brand-name Crestor is less expensive on a per-day treatment basis compared to Lipitor. However, cost should not be your primary consideration in determining which cholesterol-lowering medication is right for you.
Regarding generic versions; Rosuvastatin (generic for Crestor) and Atorvastatin (generic for Lipitor), costs are significantly lower:
- Rosuvastatin comes in packs ranging from 15 up to 1000 capsules with prices starting as low as $0.14 per day and may go up depending upon the dosage and quantity purchased.
- Atorvastatin similarly ranges in pack sizes with an approximate daily cost falling between $0.12 - $1 per day based on dosages and quantity bought at one time.
Please note that pricing can vary widely based on several factors including location-specific retail pricing variations or insurance coverage differences among others.
Popularity of Crestor and Lipitor 2015
Rosuvastatin, in generic form as well as under the brand name Crestor, was estimated to have been prescribed to about 21 million people in the US in 2015. Rosuvastatin accounted for just over 20% of statin prescriptions in the US that year. It has shown a steady increase in prevalence since its introduction.
Atorvastatin, including brand versions such as Lipitor, was prescribed to around 23.8 million people in the USA in 2015. In terms of statin prescriptions, atorvastatin held an approximate share of almost one quarter (25%) during this period - slightly higher than rosuvastatin's share and making it one of the most commonly used drugs for lowering cholesterol levels. The use of atorvastatin has remained relatively stable throughout recent years.
Conclusion
Both Crestor (rosuvastatin) and Lipitor (atorvastatin) have been proven effective in managing high cholesterol levels and are backed by numerous clinical studies indicating their effectiveness over placebo treatments. While both drugs work similarly - by inhibiting the enzyme HMG-CoA reductase that plays a crucial role in the production of cholesterol - they are prescribed under different circumstances due to their varying potencies.
Crestor is often considered when a more potent statin is needed, as it reduces LDL-cholesterol more than Lipitor at equivalent doses. However, Lipitor has a longer history of use and may be preferred for patients with less aggressive lipid targets or those who prefer once-daily dosing.
Both drugs are available in generic forms which can lead to substantial cost savings, especially for patients paying out-of-pocket. The therapeutic effects of both Crestor and Lipitor may not be noticeable right away as cholesterol reduction takes time.
The side effect profiles are similar between these two drugs; being generally well-tolerated but also include muscle pain, liver damage, digestive problems among others. Both require monitoring of liver enzymes before starting treatment and during therapy if signs or symptoms occur suggesting possible liver injury.
