To determine whether the SNP rs4149056 in SLCO1B1 alters the pharmacodynamics of pravastatin.
rs4149056 was genotyped in 626 pravastatin-treated participants in the WOSCOPS trial and the response after 1 year of treatment was compared between the different genotypes.
Pravastatin reduced serum LDL cholesterol by 22.2% in TT homozygotes, by 22.2% in TC heterozygotes and by 17.7% in CC homozygotes (TT + TC vs. CC P value 0.33). There were no significant differences in the response of total cholesterol, LDL, HDL, triglycerides or CRP to pravastatin between the genotypes.
The rs4149056 SNP did not significantly affect the pharmacodynamics of pravastatin.
确定 SLCO1B1 中的 SNP rs4149056 是否改变普伐他汀的药效学。
在 WOSCOPS 试验中对 626 名接受普伐他汀治疗的参与者进行了 rs4149056 基因分型,并比较了不同基因型在 1 年治疗后的反应。
TT 纯合子中普伐他汀降低血清 LDL 胆固醇 22.2%,TC 杂合子中降低 22.2%,CC 纯合子中降低 17.7%(TT+TC 与 CC 相比,P 值为 0.33)。不同基因型的总胆固醇、LDL、HDL、甘油三酯或 CRP 对普伐他汀的反应无显著差异。
rs4149056 SNP 对普伐他汀的药效学没有显著影响。
