What is Crestor?
Crestor is original rosuvastatin drug manufactured by AstraZeneca. It lowers "bad" LDL cholesterol and increases "good" HDL, and stronger than other statins. Doctors prescribe pills Crestor to people who have high risk of cardiovascular catastrophe, to protect them from a heart attack, and ischemic stroke. In studies of rosuvastatin was attended by many thousands of patients. All of them prescribed the original drug Crestor. Pills rosuvastatin competing firms have a weaker evidence base, but are cheaper. All concerned about medication side effects Crestor and other statins. Below explained in detail what they are, how to alleviate or remove entirely. Read also the instructions for use, written in accessible language. Learn the indications, contraindications, dosages, the regimen.Crestor reduces "bad" LDL cholesterol in the blood, partially blocking its production in the liver. Also reduces the concentration of triglycerides, apolipoprotein b, lipoprotein very low density (VLDL). Increases "good" HDL cholesterol. Reduces chronic indolent inflammation in the blood vessels. Improves the performance of C-reactive protein and other markers of inflammation. The results of the blood tests begin to improve in 1-2 weeks, maximum effect in 2-4 weeks.
Crestor (Rosuvastatin) General Information
Crestor (Rosuvastatin) is a statin-induced hypolipidemic drug designed to reduce the production of "bad" and increase the concentration of "good" cholesterol in the blood plasma. The drug of the last (fourth) generation is effectively used in the treatment of hypercholesterolemia and for the prevention of atherosclerosis and its consequences.
Cleaning the blood vessels and preventing the formation of atherosclerotic plaques, it inhibits the development of infarction and ischemic stroke in patients with high cardiovascular risk. Rosuvastatin is one of the most studied drugs in the statin group - its effectiveness has been proven experimentally on 170,000 volunteers.
Method of application and dose:
The drug is prescribed inside at any time of the day regardless of the meal. The tablet should be swallowed whole with water without chewing or crushing. Before the start of drug therapy Crestor® patient is required to begin to comply with the standard hypolipidemic diet and continue to observe her during treatment. The dose should be selected individually depending on indications and therapeutic response, taking into account the current recommendations for target levels of lipids. Patients with renal insufficiency mild or moderate severity dose adjustment is not required. Patients with moderate renal impairment, the recommended initial dose of the drug 5 mg.

When Do You Need to Use Crestor (Rosuvastatin)?
The uniqueness of the latest generation of statin is that it is used with an elevated C-reactive protein. It is this indicator, rather than NSAIDs and NPLP, that provides a reliable picture of vascular risks. In small, in comparison with other statin dosages, the drug more actively normalizes the lipid balance.
Excessive reduction in the production of harmful cholesterol leads to depressive states, loss of memory, a reduction in life, so it is important to monitor the rate of cholesterol. Patients of adulthood, as well as patients with renal and hepatic dysfunction, do not have special recommendations for dosage.
Rosuvastatin is a fourth-generation drug with an extended spectrum of effects. It is used in the following pathologies:
- Hypercholesterolemia, characterized by increased plasma concentrations of cholesterol;
- Hypertriglyceridemia due to high triglycerol;
- Homozygous hypercholesterolemia of genetic nature;
- Prevention of the consequences of atherosclerosis - hypertension, ischemic heart disease, cerebral stroke in patients of mature (after 50) age.
How Does Rosuvastatin Work?
The active component of the drug has a hypolipidemic effect. Rosuvastatin inhibits the enzyme HMG-CoA-reductase, responsible for the production of mevalonate - the precursor of cholesterol. The agent acts directly on the hepatocytes (liver cells) responsible for the production of its own (endogenous) cholesterol. Increasing the number of low-density lipoprotein receptors on the surface of hepatocides, it activates the removal of excess cholesterol from the circulatory system. The preparation stimulates the synthesis of nitrogen.
An important difference between Rosuvastatin and other statins is that it not only fights against "bad" cholesterol, but also reduces chronic inflammation, which, according to many scientists, is the main cause of atherosclerosis. The drug stimulates the synthesis of nitrogen, contributing to the relaxation of blood vessels, and creates a so-called pleiotropic (additional) effect.
After using the statin, the active ingredient quickly, though not completely, enters the circulatory system, evenly distributed throughout the tissues of the body. It is absorbed more slowly than its analogues and the period of excretion is longer. The maximum plasma concentration of the active ingredient is observed after 5 hours after use.
Which Dosage of Rosuvastatin Should You Take?
Rosuvastatin is taken inside (regardless of food intake, at any time of the day). Do not grind and not chew, swallow it, washed down with water. The initial dose is 1 time per day 10 mg; it is possible to increase the dose at 4 weeks to 20 mg. An increase in the dose to 40 mg is possible only under medical supervision in patients with severe familial homozygous hypercholesterolemia with a high risk of developing cardiovascular complications that did not achieve the desired result with 20 mg of the drug.
Patients who have risk factors for myopathy, the initial dose is 5 mg. When used with gemfibrazilom dose of rosuvastatin should not be more than 10 mg / day. With mild or moderate renal failure, as well as in elderly patients, dose adjustments are not required.
Before the treatment and throughout the period of therapy with rosuvastatin, a standard lipid-lowering diet should be followed. When treating every 2-4 weeks, it is necessary to monitor the lipid profile and, if necessary, adjust the dose of rosuvastatin. A dose of 40 mg is contraindicated in patients who have risk factors for rhabdomyolysis (familial or personal history of muscular disease, hypothyroidism, mean renal insufficiency (creatinine clearance less than 60 ml / min), alcohol abuse, myotoxicity when taking fibrates or other inhibitors of HMG-CoA reductase, patients of the Asian race, simultaneous reception of fibrates, conditions that are accompanied by an increase in the content of the drug in the systemic circulation). Patients who take 40 mg of the drug are recommended to monitor the indicators of the functional state of the kidneys.
Who Mustn't Take the Drug: Contraindications

- When interacting with drugs of nicotinic acid, the risk of manifestation of renal insufficiency, as well as rhabdomyolysis, increases;
- With diuretics, the risk of lowering the level of endogenous steroid hormones increases;
- When interacting with additional lipid-lowering agents, the likelihood of multiple side effects increases;
- With cardiac glycosides, the concentration of digoxin increases;
- When interacting with immunosuppressants, the probability of developing acute renal failure increases, as well as rhabdomyolysis;
- When interacting with anticoagulants, the probability of bleeding increases;
- With antifungal agents increases the likelihood of developing acute renal failure, as well as rhabdomyolysis;
- With alcohol, the risk of liver damage increases - therefore, it should be as limited as possible.
