What therapeutic benefit does rosuvastatin provide for patients?

Rosuvastatin is classified as a statin, which is a type of medication primarily used to manage cholesterol levels in patients. Its therapeutic benefit lies in its ability to lower low-density lipoprotein (LDL) cholesterol, often referred to as "bad" cholesterol, while simultaneously raising high-density lipoprotein (HDL) cholesterol, known as "good" cholesterol. By effectively reducing LDL levels, rosuvastatin contributes to the prevention of cardiovascular diseases, such as heart attacks and strokes, which are particularly associated with high cholesterol levels. This makes it a vital medication in the management of hyperlipidemia and overall cardiovascular health.

The other options provided do not align with the therapeutic effects of rosuvastatin. Increasing blood pressure, blood glucose, or promoting weight gain are not benefits associated with this medication and are, in fact, contrary to the goals of cholesterol management and cardiovascular risk reduction.
