Enhanced oxidizability of ubiquinol and alpha-tocopherol during lovastatin treatment.

Abstract:

:A double-blinded, placebo-controlled cross-over trial was carried out with 27 hypercholesterolemic men with coronary heart disease. During the 6-week treatment period lovastatin (60 mg/day) decreased fasting serum LDL cholesterol by 45%, LDL phosphorus by 38% and apoB by 33%. Ubiquinol content diminished by 13% as measured per LDL phosphorus. When LDL was oxidized ex vivo with AMVN both LDL ubiquinol and alpha-tocopherol were exhausted faster after lovastatin treatment compared to placebo, by 24% (P < 0.005) and 36% (P < 0.0001), respectively. Lag time in copper-induced oxidation of LDL decreased by 7% (P < 0.01). This suggests diminished antioxidant-dependent resistance of LDL to the early phase of oxidative stress.
