Rates of type 2 diabetes, obesity and their associated detrimental cardiovascular effects are rapidly increasing. Despite the availability of several treatment options for type 2 diabetes and the use of intensive regimens combining several antidiabetic drugs, less than one-half of all patients reach a target glycosylated hemoglobin level of less than 7%. Disease progression due to ongoing deterioration of pancreatic islet cell health and beta-cell function is likely responsible. Therefore, there is a need to identify new pharmacological compounds that may not only treat hyperglycemia, but may also correct impaired glucose homeostasis and preserve endogenous beta-cell function. Identification and characterization of the incretin system and its effect on glucose homeostasis have resulted in the development of new antidiabetic agents that target these concerns. The current review examines the incretin effect and the pharmacological agents that have been developed based on the understanding of this physiological system. The influence of incretins on the cardiovascular system beyond the proatherogenic effect of type 2 diabetes will also be discussed.
2 型糖尿病、肥胖及其相关心血管不良后果的发生率正在迅速增加。尽管有多种 2 型糖尿病的治疗选择,并且使用了联合多种抗糖尿病药物的强化治疗方案,但只有不到一半的患者达到糖化血红蛋白目标值<7%。这可能是由于胰岛细胞健康和β细胞功能持续恶化导致疾病进展所致。因此,需要确定新的药理化合物,这些化合物不仅可以治疗高血糖,还可以纠正葡萄糖稳态受损并保留内源性β细胞功能。肠促胰岛素系统的鉴定和特征及其对葡萄糖稳态的影响导致了针对这些问题的新型抗糖尿病药物的开发。目前的综述检查了肠促胰岛素的作用以及基于对这一生理系统的理解而开发的药理学制剂。还将讨论肠促胰岛素对心血管系统的影响,超出了 2 型糖尿病的动脉粥样硬化作用。
