Generic Name

Rosuvastatin

Brand Name

Crestor, generics

Drug Group

HMG-CoA reductase inhibitor (statin)

Commonly Used For

This medication is used to:

• Lower LDL cholesterol and triglycerides.
• Increase HDL cholesterol.
• Prevent cardiovascular events.

Key Characteristics

• Form: Oral tablets (5 mg, 10 mg, 20 mg, 40 mg) (detailed in Dosage section).
• Mechanism: Inhibits HMG-CoA reductase, reducing cholesterol production and upregulating LDL receptors.
• Approval: FDA-approved (2003 for Crestor) and EMA-approved for dyslipidemia and cardiovascular risk reduction.

3. Indications and Uses of Rosuvastatin

Rosuvastatin is indicated for lipid management and cardiovascular protection, leveraging its cholesterol-lowering effects:

• Hyperlipidemia: Treats primary hypercholesterolemia (heterozygous familial and non-familial) and mixed dyslipidemia, reducing LDL-C by 45–55%, per AHA/ACC guidelines.
• Prevention of Cardiovascular Events: Reduces the risk of myocardial infarction, stroke, and revascularization in patients with or without established CVD, supported by the JUPITER trial.
• Homozygous Familial Hypercholesterolemia (HoFH): Manages HoFH in adults and children (8+ years), lowering LDL-C when combined with other lipid-lowering therapies, per pediatric cardiology protocols.
• Atherosclerosis: Slows progression and stabilizes plaques in patients with carotid intima-media thickness, enhancing vascular health, with evidence from imaging studies.
• Type 2 Diabetes with Dyslipidemia: Used in T2DM patients to reduce cardiovascular risk, improving lipid profiles, supported by endocrinology research.
• Chronic Kidney Disease (CKD): Employed off-label to reduce cardiovascular mortality in CKD patients, preserving renal function, with nephrology data.
• Non-Alcoholic Fatty Liver Disease (NAFLD): Investigated off-label to reduce liver fat and inflammation in NAFLD patients, with hepatology evidence from cohort studies.
• Rheumatoid Arthritis: Explored off-label to lower cardiovascular risk in RA patients with dyslipidemia, improving outcomes, supported by rheumatology trials.
• Post-Transplant Hyperlipidemia: Managed off-label in organ transplant recipients to control cholesterol levels, adjusting for immunosuppression, per transplant medicine guidelines.
• Pediatric Dyslipidemia: Treats heterozygous familial hypercholesterolemia in children (8–17 years), enhancing long-term cardiovascular health, with pediatric lipid studies.

Note: This drug requires regular lipid monitoring; consult a healthcare provider for individualized therapy and risk assessment.

4. Dosage of Rosuvastatin

Important Note: The dosage of this statin must be prescribed by a healthcare provider. Dosing varies by indication, patient response, and tolerability, with adjustments based on clinical evaluation.
