二甲双胍（guā）（英语：Metformin）^{[注 1]}，常见商品名格华止、库鲁化（Glucophage），为治疗2型糖尿病的一线药物^[3]^[4]，特别是针对超重的患者^[5]。本品也可用于治疗多囊卵巢综合症^[3]，少数研究显示也能用于预防糖尿病患者包含如心血管疾病及癌症的并发症^[6]^[7]。本品属于口服药物^[3]，且用药不会造成体重增加^[7]。

二甲双胍在人体通常没有显著副作用^[8]。常见副作用包含腹泻、恶心，以及腹痛^[3]，造成低血糖的机会不大^[3]。但值得关注的是，不当用药可能会导致乳酸中毒（英语：Lactic acidosis），严重者甚至会死亡^[9]。肝病、肾功能衰竭者不宜服用本品^[3]，妊娠期间用药目前没有已知影响，但妊娠糖尿病一般建议以胰岛素进行治疗^[3]^[10]。本品属于双胍类药物^[3]，借由降低肝脏糖质新生及提升胰岛素敏感度来达到治疗的效果^[3]。

二甲双胍最早于1922年发现^[11]，但直到1950年代，法国内科医师让·斯特恩（Jean Sterne）开启了二甲双胍人类应用的临床研究^[11]。1957年，本品开始在法国用于药用，并于1995年开始于美国使用^[3]^[12]。本品列名于世界卫生组织基本药物标准清单之中，为基础公卫体系必备药物之一^[13]。目前相信口服给药是最有效的给药途径^[11]，本品属于通用名药物^[3]。2014年本品于发达国家的批发价为0.21至5.55美元之间^[14]。在美国，一个月疗程的药物花费约于 5 至 25 美元之间^[3]。

药理

二甲双胍的分子药理机制目前尚不完全清楚。已知其至少作用于肝脏，减少糖异生（即葡萄糖的生产）与减轻胰岛素抵抗^[15]。有研究表明二甲双胍可激活单磷酸腺苷活化的蛋白激酶（英语：AMP-activated protein kinase）（AMP-activated protein kinase，AMPK），是二甲双胍抑制肝脏糖异生、在胰岛素信号传导通路中提高胰岛素的敏感性不可缺少的机制之一^[16]。AMPK作为蛋白激酶不仅在胰岛素信号传导通路中，在全身能量平衡以及葡萄糖和脂肪的代谢中也起着重要作用^[17]。动物实验和临床研究均表明二甲双胍可诱导糖尿病的粪便微生物菌群构成发生重大变化，不仅可能有助于胰高血糖素样肽-1（GLP-1）的分泌及作用，还证实可改善胰岛素的敏感性，也是其抗2型糖尿病作用的重要机制之一^[18]^[19]。

优势

不会增加体重
与其他药品相比不易造成低血糖
减少三酸甘油酯
对低密度脂蛋白有很好的效果
对血压无影响
价格低廉

缺点

患中到重度肾脏疾病或心脏病者忌用，因为可能由于酗酒导致乳酸性酸中毒。
肠胃道症状，包括恶心、腹泻、腹痛
维生素B12缺乏
金属味觉

抗衰老研究

一些资料显示，服用二甲双胍的糖尿病患者，其存活率甚至超过其他条件类似但未患糖尿病的人群^[20]，而对二甲双胍在人类身上是否有抗衰老效果的临床实验预计于2016年冬在美国开始进行。流行病学研究表明，可预防心脏病、癌症和阿兹海默症等, 令致死疾病减少身体较健康，食十年以上整体增加一成多寿命。 ^[21]
