Maintenance of glucose homeostasis involves the interplay of multiple glucoregulatory factors, including the pancreatic β-cell hormones insulin and amylin. Amylin, a neuroendocrine hormone, is secreted in response to nutrient intake and suppresses postprandial glucagon secretion, helps regulate gastric emptying, and reduces food intake. Patients with diabetes are deficient in both insulin and amylin - contributing to postprandial hyperglycemia. Pramlintide, an analogue of amylin, is the active ingredient in the SYMLIN (pramlintide acetate) injection. SYMLIN is indicated as an adjunctive treatment for insulin-using patients with diabetes and works through mechanisms similar to those of amylin. Clinical trials have demonstrated that pramlintide therapy improves postprandial glucose control, lowers A1C, and is accompanied by a reduction in body weight. Mild-to-moderate nausea and an increased risk of insulin-induced severe hypoglycemia have been the most common side effects. These side effects can be mitigated by gradual pramlintide dose escalation during treatment initiation and proactive mealtime insulin dose reduction upon initiation of pramlintide therapy.
维持葡萄糖稳态涉及多种葡萄糖调节因子的相互作用,包括胰腺β细胞激素胰岛素和胰淀素。胰淀素是一种神经内分泌激素,在营养物质摄入后分泌,可抑制餐后胰高血糖素分泌,有助于调节胃排空,并减少食物摄入量。糖尿病患者胰岛素和胰淀素均缺乏,这会导致餐后高血糖。普兰林肽是胰淀素的类似物,是SYMLIN(醋酸普兰林肽)注射液中的活性成分。SYMLIN被指定为糖尿病胰岛素治疗患者的辅助治疗药物,其作用机制与胰淀素类似。临床试验表明,普兰林肽治疗可改善餐后血糖控制,降低糖化血红蛋白(A1C),并伴有体重减轻。轻度至中度恶心以及胰岛素诱发严重低血糖风险增加是最常见的副作用。在治疗开始时逐渐增加普兰林肽剂量,并在开始普兰林肽治疗后主动减少餐时胰岛素剂量,可减轻这些副作用。
