Effect of concomitant icosapent ethyl (eicosapentaenoic acid ethyl ester) on the pharmacokinetics of atorvastatin.
Ontology highlight
ABSTRACT: Icosapent ethyl is a high-purity prescription form of eicosapentaenoic acid ethyl ester approved as an adjunct to diet to reduce triglyceride levels in adult patients with triglyceride levels ?500 mg/dL (?5.65 mmol/L). The objective of this open-label, drug-drug interaction study was to examine the effects of icosapent ethyl on the steady-state pharmacokinetics of atorvastatin, a commonly prescribed medication in patients with dyslipidaemia.Thirty healthy subjects received atorvastatin 80 mg/day on days 1-7, icosapent ethyl 4 g/day on days 8-28, and co-administration on days 29-35. Primary end-points were natural log-transformed maximum plasma concentration (C(max)) and area under the concentration-versus-time curve from 0 to 24 h (AUC(0-24)) for atorvastatin, 2-hydroxyatorvastatin, and 4-hydroxyatorvastatin with and without icosapent ethyl.Of the 30 subjects enrolled, 26 completed the study. The 90% confidence intervals for C(max) and AUC(0-24) least-squares geometric mean ratios were within the 0.80-1.25 bounds. Concomitant administration of icosapent ethyl and atorvastatin was safe and well tolerated and icosapent ethyl did not significantly change the steady state C(max) and AUC(0-24) of atorvastatin, 2-hydroxyatorvastatin, or 4-hydroxyatorvastatin.At steady-state concentrations, icosapent ethyl did not have an effect on the pharmacokinetics of atorvastatin. Co-administration of icosapent ethyl and atorvastatin was safe and well tolerated in healthy adult subjects.
