Does Amlodipine And Atorvastatin Interact with Atorvastatin?
CDI records a major classification for Amlodipine And Atorvastatin and Atorvastatin. The stored summary is: 7 DRUG INTERACTIONS Data from a drug-drug interaction study involving 10 mg of amlodipine and 80 mg of atorvastatin in healthy subjects indicate that the pharmacokinetics of amlodipine are not altered when the drugs are co-administered. The effect of amlodipine on the pharmacokinetics of atorvastatin showed no effect on the C max : 91% (90% confidence interval: 80 to 103%), but the AUC of atorvastatin increased by 18% (90% confidence interval: 109 to 127%) in the presence of amlodipine, which is not clinically meaningful. No drug interaction studies have been conducted with amlodipine besylate and atorvastatin calcium and other drugs, although studies have been conducted in the individual amlodipine and atorvastatin components, as described below: Amlodipine Increased Risk of Myopathy and Rhabdomyolysis ( 2 , 5.1 , 7.3 , 12.3 ) Cyclosporine, tipranavir plus ritonavir, glecaprevir plus pibrentasvir Avoid atorvastatin Clarithromycin, itraconazole, saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir, elbasvir plus grazoprevir,letermovir Do not exceed 20 mg atorvastatin daily Nelfinavir Do not exceed 40 mg atorvastatin daily Lopinavir plus ritonavir, simeprevir, fibric acid derivatives, erythromycin, azole antifungals, lipid-modifying doses of niacin, colchicine Consider the risk/benefit of concomitant use with atorvastatin Other Lipid-Lowering Medications: Increased risk of myopathy (7) . Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug.
