RTV (Rosuvastatin): Advanced Statin for Lipid Management

RTV contains Rosuvastatin, a selective and competitive HMG-CoA reductase inhibitor. It lowers blood cholesterol by blocking the liver enzyme responsible for producing it, increasing surface LDL receptors to clear "bad" cholesterol, and reducing the production of VLDL particles.

📋 Indications: Cardiovascular Protection

RTV is prescribed alongside a balanced diet to:

• Lower elevated Total-C, LDL-C, ApoB, and Triglycerides (TG), while increasing "good" HDL-C.

• Manage primary hyperlipidemia, mixed dyslipidemia, and hypertriglyceridemia.

• Slow the progression of atherosclerosis (plaque buildup in arteries).

• Reduce the risk of myocardial infarction (heart attack), stroke, and arterial surgeries in high-risk patients.

🥄 Dosage & Administration (Asian Patient Protocol)

• Asian Patients: Initiation at 5 mg once daily must be strongly considered due to increased drug exposure.

• High Risk (MI/Stroke): Up to 40 mg once daily.

• Renal Impairment: For severe impairment ($ClCr < 30$ mL/min), start at 5 mg and never exceed 10 mg once daily.

• Critical Limits with Interacting Drugs:

  • Cyclosporine: Limit RTV to 5 mg once daily.

  • Gemfibrozil, Lopinavir/Ritonavir, Atazanavir/Ritonavir: Limit RTV to 10 mg once daily. (Avoid Gemfibrozil combination entirely if possible).

🛑 Contraindications & Liver Safety

• Do not use if you have: Active liver disease or unexplained, persistent elevations in liver enzymes (transaminases). Routine liver tests are required before starting and periodically during treatment.

• Pregnancy & Lactation: Strictly contraindicated. If you suspect you are pregnant, stop taking RTV immediately. Do not use while breastfeeding.

⚠️ Precautions & Muscle Safety

⚠️ Myopathy/Rhabdomyolysis Warning: Immediately report unexplained muscle pain, tenderness, or weakness (myalgia), especially if accompanied by fever or dark urine. RTV must be stopped if muscle injury is suspected or if creatinine kinase levels spike.
