Description

What is Crestor?

Crestor is a tablet used to medicate high cholesterol, and is manufactured by AstraZeneca. It is taken as a single daily dose. Administration typically begins with a small dose before this is gradually increased, according to its effectiveness, over a period of weeks.

High cholesterol occurs when fats which the liver produces increase to a point where they may cause the arteries to become narrower. This doesn’t cause any immediate physical symptoms, but can pose a number of health risks, such as: an increased susceptibility to heart disease, heart attacks, and stroke.

A number of lifestyle factors can contribute to high cholesterol. These include a poor diet, which is composed too much of saturated fats, lack of exercise, excessive alcohol consumption and smoking. You are also more likely to have high cholesterol if you have diabetes, high blood pressure, or liver or kidney disease. However, genetics can play a role too. Persons with a family history of cardiovascular disease may be more prone to high cholesterol.

Statins are an effective form of treatment for high cholesterol. Crestor belongs to this category of drugs, and contains a functioning constituent called rosuvastatin calcium. This works by lowering the amount of cholesterol the body produces.

The liver is responsible for generating fats called lipids, which are essential in helping the body to perform various functions. These are carried around the body through the bloodstream, by proteins. When lipids join with these proteins, they form something called lipoproteins, of which there are two types: high and low density. These are also commonly referred to as good and bad cholesterol, respectively.

Low density lipoproteins, or LDLs, are responsible for transporting fats out from the liver to those cells that require them. However, excessive amounts can cause these fats to gather and accumulate in arterial walls, thus increasing the chances of illness. Rosuvastatin calcium works by interfering with the function of an enzyme in the liver, which facilitates the production of LDLs. By doing so, it decreases the levels of bad cholesterol present in the body, and reduces the risk of consequential illness.

Crestor dosages

Crestor 5mg

This is the lowest available dose. 5mg may be issued as an initiation dose in cases where the patient is:

  • of Asian descent;
  • over 70;
  • has moderate kidney problems;
  • or is at risk of side effects such as muscle pain.

Crestor 10mg

10mg is the typical starting dose for most patients. However, the dose someone starts on will usually be determined by their cholesterol level, and their risk of heart attack or stroke, in addition to the factors described above. Someone who starts on 5mg may have their administration raised to 10mg in some instances.

Crestor 20mg

A doctor may choose to increase a patient’s dose from 10mg to 20mg in some cases, depending on how effective the lower dose is. Between these changes, a prescriber will wait for at least four weeks before altering the dose.

Crestor 40mg

This dose is the maximum available, and is only issued to patients who have found the lower doses to be less than sufficient, and who also have a high risk of heart attack or stroke.
