title: [Unaltered homocysteine levels during simvastatin therapy].
abstract: Homocysteinemia is regarded as a risk factor for vascular disease. Several risk factors and diseases, but also various drugs, amongst them some lipid lowering medications, have been shown to increase plasma homocysteine concentrations. We therefore assessed the influence of simvastatin on plasma homocysteine levels in 57 patients suffering from severe familial heterozygous hypercholesterolemia. After 1, 3 and 6 months of simvastatin therapy plasma homocysteine levels did not show any change compared to the levels before therapy. Males had typically higher homocysteine levels than females and concentrations in smokers were in most subgroups significantly higher than in non-smokers. No difference in patients taking either 20 or 40 mg simvastatin was apparent and no correlation to the lipid lowering action was found. These findings indicate that in contrast to a number of other lipid lowering agents, simvastatin does not affect plasma homocysteine levels.
