    1. See Statin regarding Myopathy and hepatitis risk
  3. Pregnancy (Teratogen)
  4. Acute Liver Failure or decompensated Cirrhosis
  • Mechanism
  1. See Statin
  • Efficacy
  1. See Statin
  2. Rosuvastatin 5 mg lowers LDL 45%

  • Adverse Effects
  • Safety
  1. Pregnancy Category X
  2. Contraindicated in Lactation
  • Pharmacokinetics
  1. See Statin
  2. Undergoes first pass metabolism as with most Statins (except Pravastatin)
  3. Protein binding
    1. As with most Statins (except Pravastatin), Rosuvastatin is 90% Protein bound
  4. Cytochrome P450 Metabolism
    1. Rosuvastatin, like Pravastatin, is NOT metabolized by CYP3A4 isoenzyme
  • Dosing
  • Adult
  1. Specific LDL and HDL targets have been replaced with high-intensity Statin if 10 year Cardiovascular Risk >20%
  2. High intensity Statin (age <75 years with 10 year Cardiovascular Risk >20%)
    1. Rosuvastatin 20-40 mg orally daily
  3. Low intensity Statin (age >75 years, or Statin intolerant)
    1. Rosuvastatin 25-10 mg orally daily
  4. Indications to start at lower dose (5 mg)
    1. Asians
      1. Higher drug levels leads to higher toxicity risk
    2. Renal Insufficiency (max 10 mg if CrCl < 30 ml/min)
    3. Hypothyroidism (uncontrolled)
    4. Age over 65 years
    5. Cyclosporine use (max dose 5 mg daily)
    6. Concurrent Gemfibrozil (max dose 10 mg daily)
  • Dosing
  • Child
  1. Heterozygous familial Hyperlipidemia
    1. Age 8 to 9 years old
      1. Rosuvastatin 5 to 10 mg orally daily
    2. Age 10 years and older
      1. Rosuvastatin 5 to 20 mg orally daily
  2. Homozygous familial Hyperlipidemia
    1. Age 7 to 17 years old
      1. Rosuvastatin 20 mg orally daily
  • Monitoring
  1. See Statin
  2. Liver transaminase testing (AST,ALT) is no longer routinely indicated as of March 2012
  • Drug Interactions (See Contraindications above)
  1. See Statin
  2. CYP3A4/organic anion transporting polypeptide inhibitors
    1. Cyclosporine (10-20 fold increase in Statin serum levels)
      1. Avoid with Rosuvastatin over 5 mg daily
    2. Macrolides (Erythromycin, Clarithromycin - 6-10 fold increase in Statin serum levels)
      1. Does not appear to significantly affect Rosuvastatin
      2. Azithromycin appears to be safe with Statins
    3. Protease inibitors (Atazanavir, Ritonavir, Lopinavir/Ritonavir)
      1. Avoid with Rosuvastatin over 10 mg daily
  3. CYP3A4/CYP2C9 Inhibitor
    1. Warfarin (Increased INR and bleeding risk)
      1. Among the highest risk agents with Rosuvastatin
  4. CYP2C9, CYP2C19/oragnic anion transporting polypeptide inhibitors
    1. Gemfibrozil (2-3 fold increase in Statin serum levels, >13 fold increase in Rhabdomyolysis risk)
      1. Avoid with Rosuvastatin over 10 mg daily
  5. Other interactions
    1. Mibefradil (Posicor)
    2. Niacin
    3. Alcohol
      1. Increases risk of liver enzyme elevations
