Crestat Tab 5mg, containing the active ingredient rosuvastatin, is an effective medication for managing and lowering cholesterol levels. The key benefit of the tablet lies in its ability to inhibit HMG-CoA reductase, an enzyme involved in the production of cholesterol. By blocking this enzyme, rosuvastatin reduces the synthesis of cholesterol in the liver, resulting in lower overall cholesterol levels. This is particularly important for individuals with elevated levels of low-density lipoprotein (LDL) cholesterol, commonly referred to as "bad" cholesterol, as it plays a significant role in the formation of plaque in the arteries. Remember to consult a healthcare professional for proper guidance and to closely follow the prescribed dosage and usage instructions.
