随机前停用所有口服药,转换为二甲双胍,经过2周的二甲双胍滴定至最大日剂量(2000mg)或能耐受最大日剂量(1500mg)后能够维持剂量稳定1周,且随机前3天早餐前自测血糖不低于7.5mmol/L者纳入研究。A38-week,randomised,open-label,treat-to-targettrialinadultswithtype2diabetesmellitusisgoingtocompareefficacyandsafetyofIDegAsponcedaily(OD)versusinsulinglargine(IGlar)+insulinaspart(IAsp)OD.AtWeek38,thepercentageoftotalbasaldoseswere72.5%,thebolusdoseswere27.5%.Thatmeanstheradiobetweenthemwascloseto7:3.药品名称:德谷门冬双胰岛素注射液成分:活性成分:德谷胰岛素和门冬胰岛素(采用重组DNA技术,利用酿酒酵母制成)。1ml溶液含有100单位德谷胰岛素和门冬胰岛素,其比值为70/30(相当于2.56mg德谷胰岛素和1.05mg门冬胰岛素)。每支预填充注射笔装有3ml溶液,含有300单位德谷胰岛素和门冬胰岛素。辅料:甘油、间甲酚、苯酚、氯化钠、醋酸锌、盐酸(用于调节pH值)、氢氧化钠(用于调节pH值)、注射用水。性状:无色液体,无浑浊,基本不含微粒物质。和锐30、门冬胰岛素的辅料大致相同,只是后两者都多了一个二水合磷酸氢二钠,起锌络合剂的作用。德谷胰岛素的辅料相同。不推荐用于治疗糖尿病酮症酸中毒。不建议儿童患者需要少于5个单位本品可单独给药,也可与口服抗糖尿病药物联合使用,或与餐时胰岛素联合使用给药时间:德谷门冬双胰岛素可灵活变动胰岛素的给药时间,只要随主餐给药即可。如果忘记给药,建议在当天下一次主餐时补充漏掉的剂量,此后恢复平时的给药方案。患者不得为了弥补遗漏剂量而进行额外给药。给药剂量及调整:德谷门冬双胰岛素应根据患者的个体需要给药。建议主要根据空腹血糖水平调整剂量。如果患者的体力活动增多、常规饮食改变或伴随其他疾病,则需调整剂量。给药时间:德谷门冬双胰岛素可灵活变动胰岛素的给药时间,只要随主餐给药即可。如果忘记给药,建议在当天下一次主餐时补充漏掉的剂量,此后恢复平时的给药方案。患者不得为了弥补遗漏剂量而进行额外给药。给药剂量及调整:德谷门冬双胰岛素应根据患者的个体需要给药。建议主要根据空腹血糖水平调整剂量。如果患者的体力活动增多、常规饮食改变或伴随其他疾病,则需调整剂量。本品可单独给药,也可与口服抗糖尿病药物联合使用,或与餐时胰岛素联合使用给药时间:德谷门冬双胰岛素可灵活变动胰岛素的给药时间,只要随主餐给药即可。如果忘记给药,建议在当天下一次主餐时补充漏掉的剂量,此后恢复平时的给药方案。患者不得为了弥补遗漏剂量而进行额外给药。给药剂量及调整:德谷门冬双胰岛素应根据患者的个体需要给药。建议主要根据空腹血糖水平调整剂量。如果患者的体力活动增多、常规饮食改变或伴随其他疾病,则需调整剂量。本品与短效/速效胰岛素在剩余餐时联合使用感谢您的聆听。
