التداخل بين أملوديبين وأتورفاستاتين وبوساكونازول

Prevention or Management Atorvastatin, Lovastatin, Simvastatin Concomitant use with posaconazole is contraindicated.

HMG-CoA Reductase Inhibitors Primarily Metabolized through CYP3A4 ( 4.4 , 7.2 )

HMG-CoA Reductase Inhibitors Primarily Metabolized Through CYP3A4 Coadministration with the HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) is contraindicated since increased plasma concentration of these drugs can lead to rhabdomyolysis [see Drug Interactions (7.2) and Clinical Pharmacology…

Quinidine HMG-CoA Reductase Inhibitors (Statins) that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Concomitant use of posaconazole with simvastatin increased simvastatin plasma concentrations which can lead to rhabdomyolysis [see Clinical Pharmacology (12.3) ].

Calcium Channel Blockers that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole may increase the plasma concentrations of calcium channel blockers that are substrates of CYP3A4.

Amlodipine and atorvastatin tablets dosage modifications are recommended for patients taking certain anti-viral, azole antifungals, or macrolide antibiotic medications [see Dosage and Administration (2) ] .

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) ].
