Changes in serum lipoproteins were studied in 14 non-insulin dependent diabetics on long-term metformin therapy, after 6 weeks' placebo, and again 6 weeks after restarting active drug therapy. Withdrawal of metformin resulted in a rise of fasting blood glucose, HbA1, serum total and low density lipoprotein (LDL) cholesterol. Restarting the drug reversed these changes. Multivariate analysis showed that serum total and LDL cholesterol varied with treatment but not with glycaemic control. Metformin can lower serum total and LDL cholesterol in non-insulin dependent diabetics and this effect is maintained long term.
对14名接受长期二甲双胍治疗的非胰岛素依赖型糖尿病患者进行了血清脂蛋白变化的研究,在服用6周安慰剂后,以及重新开始活性药物治疗6周后再次进行研究。停用二甲双胍导致空腹血糖、糖化血红蛋白、血清总胆固醇和低密度脂蛋白(LDL)胆固醇升高。重新开始用药逆转了这些变化。多变量分析表明,血清总胆固醇和LDL胆固醇随治疗而变化,但与血糖控制无关。二甲双胍可降低非胰岛素依赖型糖尿病患者的血清总胆固醇和LDL胆固醇,且这种作用可长期维持。
