盐酸二甲双胍
中文同义词: 二甲双胍盐酸盐;1,1-二甲基双胍盐酸盐;盐酸二甲双胍;甲福明二甲双胍盐酸盐;甲福明二甲双胍盐酸;甲福明二甲双胍;盐酸二甲双胍对照品;盐酸二甲双胍(USP美国药典标准品)
化学性质: 白色结晶或结晶性粉末。易溶于水,在甲醇中溶解,在乙醇中微溶,不溶于乙醚和氯仿。无臭,味苦。
用途:
盐酸二甲双胍是一种双胍类口服降糖药,又称盐酸甲福明、格华止、美迪康,降糖作用比苯乙双胍要弱,主要作用是减少A细胞胰高血糖素的分泌,促进葡萄糖转化为糖原,具有不刺激胰岛β-细胞分泌胰岛素的特性。
降糖的作用机制如下:
1.增加周围组织对胰岛素的敏感性,增加胰岛素介导的葡萄糖利用.
2.增加非胰岛素依赖的组织对葡萄糖的利用,如脑、血细胞、肾髓质、肠道、皮肤等。
3.抑制肝糖原异生作用,降低肝糖输出。
4.抑制肠壁细胞摄取葡萄糖。
5.抑制胆固醇的生物合成和贮存,降低血甘油三酯、总胆固醇水平。
临床上盐酸二甲双胍主要用于治疗单纯饮食控制不满意的Ⅱ型糖尿病患者,尤其是肥胖和伴高胰岛素血症者,用本药不但有降血糖作用,还可能有减轻体重和高胰岛素血症的效果。对某些磺酰脲类疗效差的患者可奏效,如与磺酰脲类、
小肠糖苷酶抑制剂或噻唑烷二酮类降糖药合用,较分别单用的效果更好。亦可用于胰岛素治疗的患者,以减少胰岛素用量。

Usage:
Metformin is a biguanide oral hypoglycemic agents, also known as metformin hydrochloride, Glucophage, metformin, phenformin hypoglycemic effect than to be weak, the main role is to reduce the A cell glucagon secretion, promote the conversion of glucose to glycogen, which can not stimulate islet beta cell insulin secretion.
The mechanism of hypoglycemic:
1 increase the sensitivity in the peripheral tissues to insulin, increased insulin mediated glucose utilization.
2 increase the use of non insulin dependent tissue glucose, such as brain, blood cells, renal medulla, gut, skin etc..
3 inhibition of hepatic gluconeogenesis, reduce hepatic glucose output.
4 inhibition of intestinal wall cells and glucose uptake.
5 inhibition of cholesterol biosynthesis and storage, reduce blood triglyceride, total cholesterol levels.
