Vytorin vs Crestor

Listen to the article instead of reading through it.


For patients dealing with high cholesterol levels, certain drugs can help in managing these levels and reduce the risk of heart disease. Vytorin and Crestor are two such medications that are frequently prescribed for this purpose. Both have a role to play in controlling lipid metabolism but function differently within the body.

Vytorin is a combination drug made up of ezetimibe and simvastatin. Ezetimibe works by reducing the absorption of dietary cholesterol from the intestines, while simvastatin inhibits HMG-CoA reductase, an enzyme responsible for producing cholesterol in the liver. On the other hand, Crestor or Rosuvastatin primarily belongs to statins class that also inhibit HMG-CoA reductase but it's more potent than simvastatin.

These medications not only lower low-density lipoprotein (LDL), often referred to as "bad" cholesterol but also increase high-density lipoprotein (HDL) or "good" cholesterol levels to some extent providing dual benefits.

What is Vytorin?

Vytorin, a combination of ezetimibe and simvastatin, was a significant advancement in the statin class of cholesterol-lowering drugs. Approved by the FDA in 2004, Vytorin works by reducing the absorption of dietary cholesterol in the intestines and preventing your liver from making too much cholesterol. It is prescribed for managing elevated levels of low-density lipoprotein (LDL) or "bad" cholesterol.

On the other hand, Crestor (rosuvastatin) is another member of statins that also reduces LDL levels but through slightly different mechanisms. Crestor slows down an enzyme in your liver to decrease its ability to produce bad cholesterol while increasing levels of high-density lipoprotein (HDL) or "good" cholesterol.

Both drugs effectively lower undesirable lipid profiles; however, their side effects are different due to their unique action mechanisms. Vytorin can lead to more gastrointestinal issues due to its effect on intestinal absorption compared with Crestor which mostly results in muscle-related side effects because it primarily acts within our body's metabolic processes.

What conditions is Vytorin approved to treat?

Vytorin is approved for the treatment of various types of high cholesterol conditions:

  • Primary hyperlipidemia or mixed hyperlipidemia as an adjunct to diet
  • Homozygous familial hypercholesterolemia (HoFH) in combination with other lipid-lowering treatments
  • Heterozygous familial hypercholesterolemia (HeFH) in patients aged 10 years and older who cannot control their LDL cholesterol levels by diet alone

How does Vytorin help with these illnesses?

Vytorin aids in managing high cholesterol levels by inhibiting the absorption of cholesterol in the intestines and reducing its production within the liver. It does this through a combination of two medicines, ezetimibe and simvastatin. Ezetimibe works on limiting dietary cholesterol absorption while simvastatin reduces the amount of cholesterol produced internally by your body. Cholesterol is a type of fat that plays crucial roles such as building cell membranes and producing certain hormones, but when present at high levels it can build up inside blood vessels leading to heart disease or stroke. It's considered that individuals with high LDL (low-density lipoprotein), known as 'bad' cholesterol, are more prone to these conditions. Therefore, by decreasing both sources of cholesterol intake – dietary and internal - Vytorin helps patients manage their condition and decrease their risk for cardiovascular diseases.

What is Crestor?

Crestor, also known by its generic name rosuvastatin, is a statin that decreases the levels of cholesterol and triglycerides in the blood. It does this by inhibiting an enzyme involved in the production of cholesterol in the liver. Crestor was first approved by the FDA in 2003. Unlike Vytorin which is a combination of two drugs (simvastatin and ezetimibe), Crestor contains only one active ingredient - rosuvastatin.

Crestor does not inhibit absorption of cholesterol from food like ezetimibe (one component of Vytorin) but focuses on reducing internal production instead. Its side effect profile differs somewhat from combination drugs like Vytorin; it includes common effects such as muscle pain, nausea and headaches but less frequently causes diarrhea or fatigue often associated with dual-action medications such as Vytorin.

Rosuvastatin's potent action on lowering LDL ("bad") cholesterol can be especially beneficial for patients at high risk for heart disease and stroke who have not responded adequately to other treatments.

What conditions is Crestor approved to treat?

Crestor is approved by the FDA for use in treating various conditions related to cholesterol and heart health, including:

  • High low-density lipoprotein (LDL), also known as "bad" cholesterol
  • High triglycerides, an unhealthy type of fat found in blood
  • Slow progression of atherosclerosis, the buildup of plaque in arteries over time
  • Lowering risk for heart attack, stroke and certain types of heart surgery

How does Crestor help with these illnesses?

Crestor is a medication that plays an important role in the management of elevated cholesterol levels, one of the major risk factors for cardiovascular disease. Functioning as a statin, it works by inhibiting HMG-CoA reductase, an enzyme involved in the production of cholesterol in your liver. By doing so, Crestor effectively lowers LDL (the "bad" cholesterol) and triglycerides while increasing HDL (the "good" cholesterol). This differs from Vytorin which combines two types of medicines to lower LDL; a statin and ezetimibe which reduces absorption of dietary cholesterol. While both are effective options for managing high cholesterol, Crestor can be prescribed on its own when diet modification hasn't been enough or alongside other treatments when patients have particularly high-risk profiles.

How effective are both Vytorin and Crestor?

Both Vytorin (a combination of ezetimibe and simvastatin) and Crestor (rosuvastatin) are effective lipid-lowering medications used in the treatment of high cholesterol. They were both approved by the FDA within a year of each other, with Vytorin gaining approval in 2004 and Crestor in 2003.

Vytorin works through two mechanisms to lower LDL ("bad") cholesterol: ezetimibe inhibits absorption of dietary cholesterol from the intestine, while simvastatin reduces production of cholesterol by the liver. A clinical trial conducted in 2008 demonstrated that Vytorin was more effective than statins alone at reducing LDL levels — however, it also noted that this did not translate into reduced rates of heart disease or stroke among patients taking Vytorin compared to those on statins alone.

Crestor, meanwhile, is a potent statin medication that effectively lowers LDL levels and raises HDL ("good") cholesterol levels. Clinical trials have demonstrated its effectiveness; for instance, a meta-analysis published in 2016 concluded that rosuvastatin significantly reduced risk factors associated with cardiovascular disease when compared to placebo or other common treatments.

While both drugs can be highly effective at lowering harmful cholesterol levels if taken correctly, their side effect profiles differ somewhat due to their different mechanisms of action: Statins like Crestor may carry risks such as muscle pain or weakness and increased blood sugar levels leading to type-2 diabetes. In contrast, because it combines two different types of medication – a statin (simvastatin), which could have these effects; plus ezetimibe – some patients might find they tolerate Vytorin better than standalone high-dose statins.

At what dose is Vytorin typically prescribed?

Oral dosages of Vytorin range from 10/10 mg to 10/80 mg per day, but research suggests that the lower dosage is often sufficient for treating high levels of cholesterol and triglycerides in certain patients. For Crestor, adults generally start with a dose of 5-20 mg/day depending on their LDL cholesterol levels and overall risk factors for heart disease. The doctor may adjust the dosage after a few weeks based on response and tolerance. The maximum recommended daily dose for any individual is 40mg, although this should only be used in patients who do not meet their cholesterol goal at 20mg.

At what dose is Crestor typically prescribed?

Crestor therapy typically begins at a dose of 5-10 mg/day. Depending on the patient's response and tolerance, this dosage can be gradually increased up to 20 or even 40 mg/day if required, taken once daily. This higher dosage may be considered if there is no sufficient decline in LDL cholesterol levels after several weeks at lower doses. Crestor should ideally be taken at the same time each day to maintain a steady level in your system, preferably in the evening as this is when your body produces most cholesterol. As always, it's vital to follow your healthcare professional’s instructions regarding dosage and frequency.

What are the most common side effects for Vytorin?

Common side effects of Vytorin may include:

  • Headache
  • Muscle pain or soreness (myalgia)
  • Joint pain (arthralgia)
  • Dizziness
  • Memory problems or confusion
  • Liver problems, characterized by fatigue, loss of appetite, upper belly pain, dark-colored urine, yellowing skin/eyes (jaundice).

On the other hand, patients using Crestor might experience:

  • Muscle aches and pains
  • Abdominal discomfort
  • Nausea
  • Weakness

In rare cases with both medications:

  • Allergic reactions causing swelling in your lips/tongue/throat.
  • Dark colored urine and unusual tiredness pointed towards muscle breakdown (rhabdomyolysis).

Remember that these are not exhaustive lists. If you experience any unexpected symptoms while taking either of these drugs, seek immediate medical attention.

Are there any potential serious side effects for Vytorin?

While Vytorin and Crestor are both effective in controlling high cholesterol levels, they may produce different side effects. For Vytorin users, the following symptoms may indicate serious health concerns:

  • Signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue or throat.
  • Liver problems - upper stomach pain, tiredness, loss of appetite, dark urine or jaundice (yellowing of the skin or eyes)
  • Kidney issues - little or no urinating; painful or difficult urination; swelling in your feet or ankles; feeling tired or short of breath
  • Unusual muscle weakness
  • Fatigue with fever

On the other hand for Crestor users:

  • Muscle pain that is severe and does not go away
  • Dark-colored urine can indicate kidney problems
  • Yellowing of your skin and whites of your eyes could be a sign that you have liver damage

If any such symptoms occur while taking either drug it's important to seek immediate medical attention. The drugs should also be stopped until you've spoken with a healthcare professional who can assess whether it's safe for you to continue using them.

What are the most common side effects for Crestor?

Side effects that may occur with Crestor include:

  • Headache and dizziness
  • Nausea, upset stomach or constipation
  • Sleep disturbances such as insomnia
  • Muscle aches, tenderness, or weakness (myalgia)
  • Rash
  • Abnormal liver function tests

Are there any potential serious side effects for Crestor?

While Crestor is generally safe, it can occasionally cause serious side effects. These may include:

  • Signs of a severe allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue or throat
  • Memory problems or confusion
  • Kidney problems - little or no urinating; painful or difficult urination; swelling in your feet or ankles; feeling tired or short of breath
  • Liver problems - upper stomach pain, loss of appetite, dark urine, jaundice (yellowing of the skin and eyes)
  • Unexplained muscle pain, tenderness, weakness especially if accompanied by fever and unusual tiredness

If you experience any such symptoms while taking Crestor seek immediate medical attention. It's important to remember that although rare these side effects could be potentially life-threatening.

Contraindications for Vytorin and Crestor?

Both Vytorin and Crestor, like most cholesterol-lowering medications, may cause muscle pain or weakness in some people. If you notice an increase in these symptoms or any medical conditions such as liver disease becoming worse, please seek immediate medical attention.

Neither Vytorin nor Crestor should be taken if you are taking or have been taking certain drugs such as gemfibrozil (a type of fibrate), cyclosporine (an immunosuppressant) and certain antifungal medicines. Always inform your doctor about all the medications you're currently on; these drugs may interact negatively with Vytorin and Crestor causing serious complications including rhabdomyolysis – a condition that can lead to kidney failure.

Moreover, both drugs should not be used by those who have active liver diseases or unexplained persistent elevations of serum transaminases. Pregnant women or women who plan to become pregnant soon also shouldn't use either drug due to potential risk to the fetus.

How much do Vytorin and Crestor cost?

For the brand name versions of these drugs:

  • The price of 30 tablets of Vytorin (10/20 mg) averages around $216, which works out to about $7.20 per day.
  • The cost for a supply of 30 tablets of Crestor (10 mg), ranges from approximately $200-$260, working out to an average per-day treatment cost between $6.70 and $8.60.

Thus, if you're taking the standard dosage for each drug (i.e., one tablet daily), then brand-name Crestor may be less expensive on a per-day treatment basis depending on your provider's prices. However, please note that cost should not be the primary consideration in determining which drug best suits your needs.

As for generic versions—Ezetimibe/Simvastatin for Vytorin and Rosuvastatin Calcium for Crestor—the costs are significantly lower:

  • Ezetimibe/Simvastatin is available in packs ranging from 30 tablets upwards with approximate costs starting at about $1 to just over $3 per day.
  • Rosuvastatin Calcium can also be bought in packs from as few as 15 up to larger quantities like 90 or even more capsules; its cost can start from under a dollar ($0.50/day) and typically doesn't exceed about $2/day.

Popularity of Vytorin and Crestor

Vytorin and Crestor are both used to manage high cholesterol levels, with the goal of reducing the risk of cardiovascular disease.

Crestor (generic name rosuvastatin) was prescribed to roughly 21.4 million people in the US in 2020 alone and accounted for a significant portion of statin prescriptions that year. It is one of several statins, which work by inhibiting an enzyme known as HMG-CoA reductase. This reduces overall cholesterol production within the body.

In contrast, Vytorin is a combination drug containing ezetimibe and simvastatin. The ezetimibe component works differently than a statin - it blocks absorption of dietary cholesterol from the small intestine rather than inhibiting its production in the liver. In 2020, about 1 million people were prescribed Vytorin in the US.

Over time, there has been an upward trend in prescriptions for Crestor due to increasing recognition of benefit from aggressive lipid-lowering therapy; this has occurred even while generic versions have become available after patent expiration.


Both Vytorin (ezetimibe/simvastatin) and Crestor (rosuvastatin) have established records of usage in patients with high cholesterol levels, supported by numerous clinical studies indicating that they are more effective than placebo treatments. In some cases, the drugs may be combined for a boosted effect, but this should only be done under careful supervision of a physician due to potential interactions. They work differently - Vytorin acts by inhibiting both cholesterol absorption in the gut (ezetimibe component), and liver's production of cholesterol (simvastatin component), while Crestor primarily lowers cholesterol by inhibiting its production in the liver.

Crestor is often considered a first-line treatment for decreasing LDL-cholesterol ("bad" cholesterol), whereas Vytorin might typically be prescribed if patients do not respond well to statins alone or need additional lipid-lowering beyond what can be achieved with statins alone.

Both drugs are available as generics which helps reduce costs significantly. Both Crestor and Vytorin may require an adjustment period where your doctor will monitor your bloodwork to ensure optimal dosing.

Side effects between these two drugs largely overlap; constipation, headaches and muscle pain being commonly reported ones. However, because it contains simvastatin, use of Vytorin requires monitoring for rare but serious side effects such as muscle damage. For either medication, medical attention should be sought promptly if any unusual symptoms occur.
