Drug Class: Statin (HMG-CoA Reductase Inhibitor) | Form: Oral Tablet | Active Ingredient: Rosuvastatin Calcium 20mg | Status: Prescription Only (Rx)
What is Ruvastat 20mg Tablet?
Ruvastat 20mg Tablet contains Rosuvastatin Calcium 20mg as its active ingredient. It belongs to the statin class of medicines — HMG-CoA reductase inhibitors — which reduce cholesterol by blocking the enzyme the liver uses to produce it. The 20mg strength is typically prescribed when lower statin doses have not achieved sufficient cholesterol reduction, or when a patient's cardiovascular risk requires a more intensive treatment approach. Ruvastat 20mg lowers harmful LDL (bad) cholesterol and triglycerides while raising HDL (good) cholesterol, and is always used alongside a healthy diet and lifestyle.
What is Ruvastat 20mg Used For?
- High Cholesterol (ہائی کولیسٹرول) — treats primary hypercholesterolaemia and mixed dyslipidaemia when diet and exercise alone are not enough
- Cardiovascular Prevention (دل کی حفاظت) — reduces the risk of heart attack, stroke, and serious heart-related events in high-risk patients
- Atherosclerosis (شریانوں میں رکاوٹ) — slows the progression of fatty plaque build-up inside blood vessel walls
- Familial Hypercholesterolaemia — treats genetically inherited high cholesterol in adults, adolescents, and children aged 6 years and above
How Does Ruvastat 20mg Work?
Rosuvastatin blocks HMG-CoA reductase — the primary enzyme the liver uses to manufacture cholesterol. When this enzyme is inhibited, the liver produces less cholesterol and compensates by pulling more LDL cholesterol out of the bloodstream. This lowers circulating LDL and triglyceride levels while increasing protective HDL cholesterol. Over time, this reduces the build-up of fatty plaques in artery walls and significantly lowers the long-term risk of blocked arteries, heart attacks, and strokes.

Frequently Asked Questions
Is Ruvastat 20mg stronger than Ruvastat 10mg?
Yes — Ruvastat 20mg contains double the dose of rosuvastatin and is prescribed when 10mg has not achieved the target cholesterol reduction, or when a patient's cardiovascular risk requires more intensive treatment.
Can I stop Ruvastat 20mg once my cholesterol levels improve?
No — do not stop without consulting your doctor. Cholesterol levels typically return to previous levels once statin therapy is discontinued, increasing your risk of cardiovascular events.
What should I do if I notice muscle pain or weakness while taking Ruvastat 20mg?
Stop the tablet and contact your doctor immediately — unexplained muscle pain or weakness can indicate rhabdomyolysis, a rare but serious muscle condition requiring urgent medical assessment.
