What is Rosuvastatin for?

Rosuvastatin is a cholesterol lowering drug that works like Atorvastatin, which is primarily by blocking the enzyme involved in cholesterol synthesis, especially in the liver, and hence reduces cholesterol levels. It is the first-line medication used for hypercholesterolaemia or hyperlipidemia (elevated blood cholesterol).

The detailed indications of Rosuvastatin include primary hypercholesterolemia or combined (mixed) hyperlipidemia in patients who did not respond adequately to diet and other appropriate measures, homozygous familial hypercholesterolemia in patients who have not responded adequately to diet and other appropriate measures, and prevention of cardiovascular events in patients with cardiovascular disease or at high risk of having a cardiovascular event (e.g. people who smoke, people with diabetes).

How to use it?

Rosuvastatin is taken by mouth as tablets. The dose range of Rosuvastatin is 5 to 40 mg once daily. The dose of Rosuvastatin can be adjusted based on your cholesterol level by your doctor at least every 4 weeks. Usually, a lower dose is used in the Asian population.
