Amlodipin ve atorvastatin ve Dronedaron etkileşimi

• Statins: Avoid simvastatin doses greater than 10 mg daily.

• Calcium channel blockers (CCB): Initiate CCB with low dose and increase after ECG verification of tolerability.

Calcium Channel Blockers Calcium channel blockers with depressant effects on the sinus and AV nodes could potentiate dronedarone's effects on conduction.

Give a low dose of calcium channel blockers initially and increase only after ECG verification of good tolerability [see Drug Interactions (7.3) , Clinical Pharmacology (12.3) ] .

Calcium Channel Blockers Verapamil and diltiazem are moderate CYP3A inhibitors and increase dronedarone exposure.

Impact of Other Drugs on Amlodipine CYP3A Inhibitors Co-administration with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction.

Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment [see Clinical Pharmacology (12.3) ] .

Atorvastatin plasma levels can be significantly increased with concomitant administration of inhibitors of CYP3A4 and transporters.

Drug Interactions that may Increase the Risk of Myopathy and Rhabdomyolysis with Atorvastatin Cyclosporine or Gemfibrozil Clinical Impact: Atorvastatin plasma levels were significantly increased with concomitant administration of atorvastatin and cyclosporine, an inhibitor of CYP3A4 and OATP1B1 [see Clinical Pharmacology (12.3) ].

Anti-Viral Medications Clinical Impact: Atorvastatin plasma levels were significantly increased with concomitant administration of atorvastatin with many anti-viral medications, which are inhibitors of CYP3A4 and/or transporters (e.g., BCRP, OATP1B1/1B3, P-gp, MRP2, and/or OAT2) [see Clinical Pharmacology (12.3) ].
