Atorvastatin
Dosing in kidney impairment
Renal Impairment Renal impairment is a risk factor for myopathy and rhabdomyolysis. Monitor all patients with renal impairment for development of myopathy. Renal impairment does not affect the plasma concentrations of atorvastatin calcium tablets, therefore there is no dosage adjustment in patients with renal impairment [see Warnings and Precautions and Clinical Pharmacology ].
Dosing in liver impairment
Hepatic Impairment In patients with chronic alcoholic liver disease, plasma concentrations of atorvastatin calcium tablets are markedly increased. Cmax and AUC are each 4-fold greater in patients with Childs-Pugh A disease. Cmax and AUC are approximately 16-fold and 11-fold increased, respectively, in patients with Childs-Pugh B disease.
Atorvastatin calcium tablets is contraindicated in patients with acute liver failure or decompensated cirrhosis [see Contraindications ].
