Crestor 40mg includes Rosuvastatin, which is a powerful statin medicine widely used in Australia for lowering cholesterol levels and decreasing the likelihood of suffering from cardiovascular illnesses, including heart attacks and stroke. It is part of the class of medicines known as HMG CoA reductase inhibitors. They are used to stop the production of cholesterol in the liver.
What is Crestor 40mg?
Crestor offers 40mg of Rosuvastatin that is designed to decrease low-density lipid (LDL) cholesterol – often called “bad cholesterol”-and boost high-density lipoprotein (HDL) cholesterol (“good cholesterol”). It assists in preventing the accumulation of plaques inside blood vessels, thus reducing the chance of developing atherosclerosis as well as the associated complications of cardiovascular disease.
Key Features
- Active Ingredient: Rosuvastatin Calcium 40mg
- Form: Oral tablet
- Primary Uses: The prevention of cardiovascular diseases
- Prescription: Required in Australia
- Dosage: Usually, once per day, unless the doctor has instructed.
How Does Crestor 40mg Work?
Rosuvastatin blocks the enzyme HMG-CoA reductase. This enzyme is the key component of cholesterol production in the liver. By blocking this enzyme, Crestor decreases the production of cholesterol. It also causes the liver to clear the excess LDL cholesterol from the bloodstream. The result is a decrease in total cholesterol and slows down the process of plaque accumulation in the arteries.
When is Crestor 40mg Prescribed?
- Treatment of excessive LDL cholesterol in cases where lifestyle changes don’t suffice.
- Patients at risk of cardiovascular problems like heart attacks or stroke.
- To slow down or stop atherosclerosis for those suffering from coronary atherosclerosis in patients with coronary atherosclerosis.
- For familial hypercholesterolemia, a genetic condition causing very high cholesterol levels.
