What is Crestor

Crestor or rosuvastatin is a type "statin" which are lipid-lowering medication drugs also called HMG-CoA. When used along with diet, exercise, and weight-loss it decreases the levels of high cholesterol in the body and relieves its associated conditions. It also increases the level of the so-called good cholesterol and prevents cardiovascular diseases.

Cholesterol is a type of fat found in our blood. It has a very significant role in developing different parts of the body such as our brain and skin and in sustaining their optimal function. We obtain cholesterol from several foods we ingest such as meat, eggs, butter, cheese, and milk. The liver is in charge of processing cholesterol and delivering it to the rest of our body. Event though it is important, our body doesn't need too much cholesterol. When blood is saturated with too much of it, the arteries that carry blood around our body can get blocked. High cholesterol is a risk factor for heart attacks and strokes. People can become sick to the point where they need to take medication to reduce the amount of cholesterol in their blood. In such cases, a healthy diet and lifestyle are always recommended, Crestor is a prescription drug of great aid.

Product manufacturer

Crestor is a product developed by a Japanese company called Shionogi & Co. However, since 1998, AstraZeneca got worldwide rights on this drug. AstraZeneca indicated in 2003 that Crestor had been officially approved by the Food and Drug Administration (FDA) in the United States of America. The FDA protects and promotes public health through the regulation of many different products related to food safety, dietary supplements, prescription and medications, vaccines, biopharmaceuticals, among others. Crestor got approved in the U.S. to treat high LDL cholesterol (dyslipidemia), total cholesterol (hypercholesterolemia), and triglycerides (hypertriglyceridemia).

Understanding cholesterol

Understanding cholesterol 86690.jpg

Cholesterol is divided into two different kinds: low-density lipoprotein and high-density lipoprotein. They are also called LDL and HDL. A cholesterol blood test would help us know how much of each type we have.

  1. 1
    LDL cholesterol
    Is the most common yet the less healthy; it blocks arteries with plaque. Plaque interferes with the blood flow through the body. If you hear about bad cholesterol; then they are talking about LDL.

  2. 2
    HDL cholesterol
    Doesn't block arteries. That's the reason why they call HDL good cholesterol. HDL collects LDL cholesterol from the blood vessels and takes it back to the liver to be processed, and discharged from the body.

A suitable LDL level is below 200 milligrams per deciliter (mg/dL) (6.22 millimoles per liter, or mmol/L), and LDL should be under 100 mg/dL (3.37 mmol/L). If a blood test indicates that someone has high cholesterol, a doctor would certainly advise him to lower them. Probably that person would have to change his diet, to do more exercise, and to avoid smoking, in case he is a smoker. But what if all these actions are not enough, and the health´s individual is at risk, then medication is needed.

What are Statins?

What are Statins 59983.jpg

Statins are usually the first sort of medication that a specialist prescribes to lower LDL. Why? Statins can lower triglycerides, another kind of blood fat and at the same time, slightly increase your HDL. They work by blocking the secretion of a substance which our body requires to produce cholesterol. Other types of statins are fluvastatin, lovastatin, atorvastatin, and pravastatin. The American College of Cardiology and American Heart Association identifies four groups of people who could be benefited by Statins:

    People with a cardiovascular disease
    Anybody who have had heart attacks, mini-strokes, peripheral artery disease, or prior surgery to open or replace coronary arteries.

  2. 2
    People who have very high bad cholesterol
    Having levels of 190 mg/dL (4.9 mmol/L) or higher; indicates a serious problem in adults.

  3. 3
    People with diabetes
    People who have diabetes and levels of LDL between 70 and 189 mg/dL (1.8 and 4.9 mmol/L), especially if there is a vascular disease.

  4. 4
    Ten years risk of a stroke test
    Adults who have an LDL above 100 mg/dL (1.8 mmol/L) and whose 10-year risk of a stroke test is higher than 7.5 percent.

Side effects

Side effects 98935.jpg

Like other drugs, statins have side effects. The most common ones are related to intestinal problems, liver damage, and muscle inflammation. Statins could cause memory loss and confusion. However, an according to the FDA, these symptoms go away after a few weeks from leaving the drug. If people are taking other medication, statins drugs may interact with them, so make sure of letting your doctor know before he prescribes you. Finally, doctors recommend that if the following side effects are presented, people should report them to their physician as it might be necessary to stop taking them:

  • Depression
  • Constipation
  • Weakness
  • Dizziness
  • Sleeplessness
  • Cough.

Consumption of grapefruit during the treatment makes it more difficult for the body to make statins active.

Crestor and rosuvastatin have structural similarities with the rest of the statins; however, it contains sulfur which other statins don't. Crestor is the salt of rosuvastatin. It inhibits the enzyme HMG-CoA reductase which is the substance our body needs to produce cholesterol.

  • It can lower the risk of stroke, heart attack, and other heart difficulties in certain people with diabetes, heart-related disease, and other threats.
  • It can be consumed to treat genetic forms of high cholesterol, as well as both the heterozygous and the homozygous types. The first one is inherited from only one parent; the second is inherited from both the mother and father.


Contraindications 58948.jpg

Like most drugs, Crestor has contraindications. If the patient presents any of them, he should not start the treatment.

  • Hypersensitivity to any component of the formula
  • Liver disease or abnormal liver function
  • Elevation of serum transaminases
  • Pregnancy
  • Breastfeeding.

Crestor must not be taken while expecting a baby because it can produce serious damage to the fetus. In the case of breastfeeding, it should not be taken because of the possible disruption of the child's lipid metabolism.

Like all statins, Crestor could cause myopathy (muscle fibers to not function properly) or rhabdomyolysis (damaged skeletal muscle breaks down rapidly). People of Asian origin should be careful due to the easy absorption of rosuvastatin at a higher rate than other communities. These patients need to start with a lower dose.

People take it once a day during meals and at the same time each day. Of course, drinking alcohol or eating foods that are high in fat should be avoided. When patients are taking other medications, they should pay attention of affecting Crestor´s efficiency. In some cases, taking different drugs can increase the risk of severe muscle diseases.

Would it cause weight gain?

Would it cause weight gain 18058.jpg

Although many people claim to experience weight gain, according to a study by eHealthMe based on reports from 93,024 people, it is a small segment which is propense. Out of the 93,024 who participated in the study only 1. 89% gained weight, which is 1,762 individuals. Among them:

  • 69.23% were females and 30.77% were males.
  • 12.16% were aged between 40 to 49 years old.
  • 28.22% were aged between 50 to 59 years old.
  • 56.3% were aged between 60 to 69 years old.

So although there is a possibility of gaining weight, it is quite segmented to specific groups of people.

It is essential to have a healthy life, along with a balanced diet, physical activity and eating food that increases good cholesterol such as olive oil, beans, legumes, whole grains, high-fiber fruit, fish, omega-3, nuts, avocado and even red wine. There are several options to reduce our chances of having high bad cholesterol. Although, sometimes genetic conditions and other factors weaken our health, and in those cases, medicine is there to help us recover.
