二甲双胍因其有效的降糖、减重、降压、调脂、改善纤溶活性及胰岛素抵抗、治疗多囊卵巢综合症及非酒精性脂肪肝等作用,且副作用轻微,被广泛用于治疗2型糖尿病(Type 2 Diabetes Mellitus, T2DM),目前已成为T2DM治疗的一线用药。近些年国内外部分学者认为,长期服用二甲双胍治疗影响消化道维生素B12 (VitB12)的吸收,从而升高血浆同型半胱氨酸(Homocysteine, Hcy),进一步促进心血管疾病和糖尿病并发症的发生。建议二甲双胍联合VitB12治疗糖尿病人,可预防血浆同型半胱氨酸升高,延缓糖尿病各种并发症的发生。同时也为临床二甲双胍的应用提供帮助和指导。 Metformin is effective in reducing glucose, reducing body weight, lowering blood pressure, regu-lating blood lipids, improving fibrinolytic activity and insulin resistance, treating polycystic ovary syndrome and nonalcoholic fatty liver with mild side effects. It has been widely used in the treat-ment of type 2 diabetes mellitus (T2DM) and has become a first-line drug for type 2 diabetes mellitus treatment. In recent years, some scholars at home and abroad believe that long-term use of metformin therapy affects the absorption of vitamin B12 in the digestive tract, thus increasing the plasma homocysteine level and further promoting cardiovascular disease and the occurrence of diabetic complications. It is suggested that metformin combined with vitamin B12 in the treatment of diabetic patients can prevent the increase of plasma homocysteine and delay the occurrence of various complications of diabetes. At the same time, it also provides help and guidance for the clinical application of metformin.
