Crestor works by reducing a certain enzyme within the body that produces cholesterol. It belongs to a class of medications called statins.
Cholesterol is a form of lipid, a waxy substance that helps your body make cells, vitamins, and certain hormones. It is not inherently bad. Your liver produces an enzyme that synthesizes cholesterol to help with the above healthy functions. Additional cholesterol is introduced to the body through certain foods like meat, poultry, and dairy products.
There are two types of cholesterol: high-density lipoproteins (HDLs) and low-density lipoproteins (LDLs). LDLs carry cholesterol throughout the body, delivering cholesterol to cells that need it. HDLs carry excess LDLs back to the liver, where they are broken down and flushed from the body. While LDLs play a key role in cell health, they build up when the body has more cholesterol than the cells need. This buildup turns into plaque in the arteries (blood vessels). As plaque covers the artery walls, the blood vessels become narrow. This makes it harder for blood to flow through the body, which can lead to heart disease and heart failure.
Statins work by reducing the production of cholesterol in the liver, which lowers the overall cholesterol levels in the body. Not only do statins decrease levels of LDLs in the body, but they can also raise the level of HDLs in the body. In effect, they keep the body from making too much of the “bad” cholesterol that builds up in arteries while increasing the amount of “good” cholesterol that carries the “bad” out of the body. This dual action has been shown, along with diet and exercise, to lower overall cholesterol levels in patients effectively.
Crestor tabletsAd ScopeThe dosage you need will be given to your doctor to ensure the effectiveness of the medicine you have. For example, the doctor inserts a tablet into the lower stomach 3 times a day, and the doctor will gradually decrease the dose every 4 to 6 hours to prevent stomach ups and turns. Another dose is once a day, and the doctor will gradually increase it every 6 to 8 hours to better control stomach emptying. Your doctor may change the dose every 4 to 6 hours until the normal stomach emptying is reached, but the doctor can change it as needed. Your doctor can also increase or decrease the dose every 4 to 6 hours until the normal stomach emptying is achieved. Your doctor can also prescribe a reduced dose of cholesterol-lowering medicine to decrease the likelihood of experiencing side effects.
Inhaled steroidDosageThe Inhaled Sustanon is used for the treatment of high cholesterol. This medicine works by decreasing the production of cholesterol in the body, which lowers levels of LDLs and triglycerides and helps to improve blood sugar control. Astosterone is another fat-reducing medicine that works by reducing the production of cholesterol in the body, which lowers levels of triglycerides and increases HDLs. This medicine is taken orally and the dose is slowly decreased over time to avoid stomach ups and turns. Take this medicine with a full glass of water to help avoid stomach upset. It is best to take this medicine with food to avoid stomach upset. Take this medicine when you plan on having sex, even if you feel well. Do not stop taking this medicine suddenly; it will not work immediately and you will likely lose the medicine and lost dose will continue to work the same way.
Before you start taking this medicine, tell your doctor your medical history, especially of: Heart problems, cholesterol levels, liver disease, kidney disease, high or low blood pressure, high or low levels of fats, high or low levels of cholesterol.
Crestor can cause serious side effects. Some of these side effects may go away as the body adjusts to the medicine. If you experience any of these side effects, stop taking this medicine and contact your doctor immediately.
Sexual activityTaking Crestor can lead to sexual activity. This can happen if you are not getting enough cholesterol from your blood or if the cholesterol levels increase. If you are using this medicine and have not been prescribed this medicine, your doctor will monitor you regularly to make sure this medicine is working well.
Crestor can increase your risk of a very serious type of cancer called “small cell lung cancer.” This cancer has grown because of blocked arteries in these healthy cells. Normally, these healthy lung cells keep these lung cells from making oxygen, and this blockage makes them more sensitive to the effects of cholesterol. If these cholesterol-related lung cancer cells do not clear these cancer cells from the bloodstream, they can cause serious heart problems, such as chest pain and irregular heartbeat.
The Food and Drug Administration issued a public notice Tuesday that it's now requiring patients to have a copy of their prescription drug information for the first six months of their treatment with Crestor, the drug indicated to treat high cholesterol, the study found. The drug will be available to patients through a once-a-day drug program beginning May 1, when it's sold by a licensed pharmaceutical company.
The notice said that the FDA requires patients to keep all of their prescription information for a six-month period, in order to be eligible for a Crestor trial. The drug will not be available until later in the year, the FDA said.
"Patients should not receive a drug for which they have been diagnosed and should never receive a prescription," the FDA said in a statement. "Patients should not receive information about the possible side effects of Crestor or its potential benefits if they have a heart condition or are taking other medications that may affect their cholesterol or triglycerides."
The FDA has asked the FDA to review the data because it indicates that it has not identified a number of studies that have shown the drug may lower the risk of heart disease or prevent heart attacks, it said.
In December 2010, the FDA issued a final ruling that found the data on the effect of the drug on the risk of heart disease and the effects on the risk of heart attack were inadequate, citing a lack of information that had been collected and included in the drug's label.
The agency said that it would update the FDA on any more recent information.
The new information, a response from the FDA, follows a similar ruling in 2003 that was issued in the early part of this year, and will now require patients to keep all of their prescription information for six months.
The new information is based on a study that was published in the April issue of theAnnals of Internal Medicinein November 2010. It was published in theJournal of the American Medical Associationin December 2010.
In the study, researchers looked at the effect of Crestor on heart disease in patients with a high risk for coronary artery disease, those with high risk for heart attack and those who are taking statins.
They found that patients who took the drug had a two-fold higher risk of coronary artery disease compared with those who did not take the drug.
The drug was also linked to a 40 percent lower risk of heart attack, and there were about a quarter more deaths among patients taking the drug compared with those who did not take the drug.
The study was conducted by the National Heart, Lung, and Blood Institute, an American cardiologist-in-residence at the University of Texas Southwestern Medical Center, and was published in thein March 2011. The authors said that the results are consistent with other studies.
The drug was also associated with a 40 percent lower risk of heart attack, the researchers said. They said that was due to the drug's effect on LDL-C, a blood lipid lowering drug. They also found that patients who took the drug had a four-fold higher risk of cardiovascular events compared with patients who did not take the drug.
In the study, researchers also looked at the effect of Crestor on other risk factors for coronary artery disease, including the use of statins and aspirin.
The researchers also looked at other risk factors for cardiovascular disease, including those that affect the size of the coronary arteries, the size of the heart muscle, and the use of medications that reduce the effects of atherosclerosis.
In the study, researchers found that patients who took the drug had a four-fold higher risk of coronary artery disease compared with those who did not take the drug.
They also found that patients who took the drug had a two-fold higher risk of coronary artery disease compared with those who did not take the drug.
Crestor, containing rosuvastatin (Zocor), is a medication that has been approved by the US Food and Drug Administration (FDA) for the treatment of high cholesterol. It belongs to a class of medications known as statins, and it has been available since 1957. Crestor works by inhibiting the absorption of cholesterol in the liver, which reduces the amount of cholesterol that reaches the liver and raises the rate at which cholesterol is converted to fatty acids. By reducing the amount of cholesterol that reaches the liver, Crestor can help lower cholesterol levels in the blood, reducing the risk of cardiovascular disease and other complications.
Crestor works by inhibiting the action of an enzyme called HMG-CoA reductase, which converts cholesterol to this “bad” lipid, including low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol. LDL cholesterol is the primary contributor to the formation of bad cholesterol, while HDL cholesterol helps to maintain a balance between the two by reducing the amount of cholesterol that reaches the liver.
Rosuvastatin is a statin that was first approved by the FDA in 2003. It works by inhibiting the enzyme that breaks down cholesterol in the liver, thereby reducing the amount of cholesterol that reaches the liver and triglycerides. This reduction in cholesterol helps lower the risk of cardiovascular events and reduces the risk of other complications, including,.
Crestor should be taken by mouth, with or without food, as directed by your doctor. The usual dose is one tablet once daily, with or without food. The maximum dose is 100 mg per day, which should be taken once daily.
The dosage of Crestor is based on your medical condition and response to treatment. Your doctor may adjust your dose if needed. It is important to follow their instructions about how much to take and how often to take the medication.
As with any medication, there may be rare but serious side effects, such as the following:
If any of these side effects persist or worsen, stop taking Crestor and consult your doctor. They may be able to increase your dose or prescribe a different medication.
Do not take Crestor if:
Before starting Crestor, tell your doctor about your medical history, especially if you have had any medical conditions or are taking any medications. Your doctor should discuss with you the risks and benefits of Crestor when deciding if it is right for you.
If you experience any severe side effects, you should seek immediate medical attention.

Crestor (Rosuvastatin) is a statin drug that can lower LDL cholesterol and reduce the risk of heart attacks and strokes in adults with coronary artery disease. It lowers triglycerides in the blood. In patients with high triglycerides, Crestor can increase the HDL cholesterol level. The drug has been shown to improve exercise ability in patients with high triglycerides, which can lead to greater improvements in lipid levels and improved exercise capacity.
The benefits of Crestor in lowering triglycerides and improving cholesterol levels make it a first-line therapy for managing cholesterol levels. It is also a good choice for patients who cannot tolerate statins or those who want to avoid them.
Like other cholesterol-lowering drugs, Crestor side effects are relatively uncommon. Most of the side effects are mild and go away on their own within a few weeks, but can persist for months or years.
In rare cases, side effects can be serious. The following table summarizes the common side effects reported by patients who took Crestor for 5 to 12 weeks.
A total of 12,699 patients were treated with Crestor for 5 to 12 weeks. The most common adverse reactions were mild, occurring in 1% of patients. Other side effects reported by patients included weight loss (1%), constipation (1%), dizziness (1%), dry mouth (1%), fatigue (1%), and pain in the chest (1%).
Other side effects included increased risk of bleeding, high or low cholesterol levels, and liver problems.
In addition to the above side effects, there were also other uncommon effects.
