Crestor is a medication that contains the active ingredient Rosuvastatin. Crestor is a statin, a type of drug that is used to treat people who have high cholesterol or who are deemed at risk of developing cardiovascular disease, stroke or heart attack. Crestor is available on prescription to people who are in good health, but who are deemed as having a high risk of developing heart disease in the future. Crestor can also be prescribed to people who have already had a heart attack, a stroke or who are suffering with cardiovascular disease in order to reduce future risk.
Crestor is a type of medication, which falls into a category of drugs called HMG-CoA reductase inhibitors. This family of drugs blocks the action of the HMG CoA Reductase enzyme in the liver. The HMG CoA Reductase enzyme makes LDL cholesterol, which is regarded as ‘bad cholesterol’. Taking Crestor also increases the levels of HDL cholesterol, which is regarded as ‘good cholesterol’.
In a recent trial of over 17,000 patients, Crestor was shown to reduce the risk of heart attack, stroke and cardiovascular disease by a staggering 47%. Strokes were cut by 48%, the need to have an angioplasty or a bypass was cut by 46% and the risk of heart attack was cut by 54%.
Every prescription medication has the potential to cause side effects, though it must be remembered that most people will not experience any side effects. Crestor can cause side effects but these are usually mild and will stop when the medication no longer taken. The side effects of Crestor include headaches, muscle pain, constipation, diarrhea, vomiting, rashes, weakness, nausea, problems with memory and depression and problems sleeping.
Pregnant women should not take Crestor. Neither should women who trying to get pregnant as the drug can affect the unborn foetus. Crestor cannot be taken by anyone with liver problems or with a history of liver problems.
Crestor can interact with medications, such as protease inhibitors, which are used to treat HIV, itraconazole, dilitazem, erythromycin, clarithromycin, verapamil fibric acid and niacin.
Patients who are already taking niacin and fibric acids may be given Crestor, but it should be prescribed with caution.
