Description
💊📉 Rosuvastatin 20mg Tablet: High-Potency Statin for Cholesterol Control & Heart Protection
Rosuvastatin 20mg is a high-strength lipid-lowering medication from the statin class (HMG-CoA reductase inhibitors), used to effectively reduce bad cholesterol (LDL), raise good cholesterol (HDL), and lower triglycerides in the blood. It is widely prescribed to manage dyslipidemia, prevent cardiovascular disease, and reduce the risk of heart attacks, strokes, and arterial blockages, especially in high-risk individuals. At 20mg strength, it offers potent LDL reduction and is often used when moderate statins are insufficient or in patients with very high cardiovascular risk.
🔬 Mechanism of Action
Rosuvastatin works by inhibiting HMG-CoA reductase, an enzyme involved in the liver’s production of cholesterol. This leads to:
-
Reduced synthesis of LDL (bad) cholesterol
-
Upregulation of LDL receptors, which increases LDL clearance from the blood
-
Decreased triglyceride levels
-
Mild increase in HDL (good) cholesterol
This comprehensive lipid profile improvement helps slow the progression of atherosclerosis (plaque buildup in arteries).
📌 Indications and Uses
Rosuvastatin 20mg is indicated for:
-
Primary hypercholesterolemia and mixed dyslipidemia
-
Familial hypercholesterolemia (heterozygous and homozygous)
-
Primary and secondary prevention of cardiovascular events in high-risk patients
-
Atherosclerotic cardiovascular disease (ASCVD)
-
Adjunct to lifestyle changes (diet, exercise)
It is especially useful in patients who require >50% LDL reduction or have statin resistance at lower doses.
💊 Dosage and Administration
-
Usual adult dose: 20mg once daily, with or without food
-
Take at the same time each day, preferably in the evening
-
Dose may be adjusted based on cholesterol levels, risk profile, and tolerance
