XI. Monitoring
XII. Drug Interactions (See Contraindications above)
- See Statin
-
CYP3A4 Inhibitors
- Azole Antifungals (Intraconazole, Ketoconazole - 10-20 fold increase in Statin serum levels)
- Increased risk of Statin Myopathy (esp. with age >65, Obesity, renal or liver Impairment)
- Avoid with Lovastatin
- Calcium Channel Blocker
- Grapefruit juice increases some Statin levels
- Lovastatin is among the drugs most affected
- Avoid with any Grapefruit juice (or minimal use)

-
CYP3A4/organic anion transporting polypeptide inhibitors
- Cyclosporine (10-20 fold increase in Statin serum levels)
- Avoid with Lovastatin over 20 mg daily
- Macrolides (Erythromycin, Clarithromycin - 6-10 fold increase in Statin serum levels)
- Avoid while on Lovastatin (or stop Statin while on Macrolide)
- Azithromycin appears to be safe with Statins
- Protease inibitors (Atazanavir, Ritonavir, Lopinavir/Ritonavir)
- Avoid with Lovastatin
- Cyclosporine (10-20 fold increase in Statin serum levels)
-
CYP3A4/CYP2C9 Inhibitor
- Amiodarone
- Increased risk of Statin Myopathy (esp. with age >65, Obesity, renal or liver Impairment)
- Avoid with Lovastatin over 40 mg daily
- Warfarin (Increased INR and bleeding risk)
- Among the highest risk with Lovastatin
- Amiodarone
-
CYP2C9, CYP2C19/oragnic anion transporting polypeptide inhibitors
- Gemfibrozil (2-3 fold increase in Statin serum levels, >13 fold increase in Rhabdomyolysis risk)
- Avoid with Lovastatin over 20 mg daily
- Gemfibrozil (2-3 fold increase in Statin serum levels, >13 fold increase in Rhabdomyolysis risk)
- Other interactions
- Mibefradil (Posicor)
- Niacin
- Alcohol
- Increases risk of liver enzyme elevations
