Glucagon-like peptide-1 receptor agonists as insulin add-on therapy in patients with inadequate glycemic control in type 2 diabetes mellitus: lixisenatide as a new therapeutic option

摘要

Despite the variety of therapeutic options for the management of type 2 diabetes mellitus, many patients fail to meet glycated hemoglobin (HbA1c) targets. The relative contribution of postprandial plasma glucose (PPG) to overall HbA1c is estimated at 40-60%, with the effect of PPG on HbA1c, being prominent in patients on basal insulin. The development of glucagon-like peptide-1 receptor agonists (GLP-1RA5) has been an important achievement in diabetes management and has become an established treatment. Of available GLP-1RAs, lixisenatide is a once-daily prandial GLP-1RA that has been shown to produce a reduction in HbA(lc) with a pronounced postprandial effect, suggesting a complementary effect between lixisenatide and basal insulin on PPG and fasting plasma glucose, resulting in a beneficial effect on body weight in all populations. Therefore, lixisenatide will make an important addition to current options for treating diabetes, especially for patients not achieving glycemic targets with basal insulin therapy.
