From National Clinical Research Inc, Richmond, Virginia (Dr McKenney); MDS Pharma Services, Phoenix, Arizona (Dr Swearingen); MDS Pharma Services, Saint-Laurent (Montreal), Quebec, Canada (Mr Di Spirito); and Reliant Pharmaceuticals Inc, Liberty Corner, New Jersey (Mr Doyle, Ms Pantaleon, Mr Kling, Dr Shalwitz).
The coadministration of prescription omega-3-acid ethyl esters (P-OM3) with a statin may present a treatment option for patients with mixed hyperlipidemia. This open-label, randomized, 2-way crossover, drug-drug interaction study evaluated the impact of P-OM3 capsules on plasma simvastatin pharmacokinetics in 24 healthy volunteers. Under fasted conditions, 80 mg simvastatin was administered with or without 4 g P-OM3 for two 14-day periods. After 14 days of dosing to achieve steady state, no significant differences were found in either the extent (AUC
) or rate (Cmax) of exposure to simvastatin or its major ß-hydroxy metabolite after coadministration of P-OM3 with simvastatin compared with administration of simvastatin alone. At steady state, the coadministration of P-OM3 capsules did not appear to affect the pharmacokinetics of simvastatin tablets. The combination of P-OM3 capsules and simvastatin appeared to be well tolerated.
Key Words: Omega-3 fatty acids omega-3-acid ethyl esters P-OM3 statins hyperlipidemia hypertriglyceridemia
