Longer acting GLP-1 receptor agonists and the potential for improved cardiovascular outcomes: a review of current literature.

With the rapidly rising incidence of Type 2 diabetes and an increasing variety of medications available for treatment, choosing the ideal regimen for patients can be challenging. Longer-acting glucagon-like peptide-1 (GLP-1) receptor agonists and devices have been recently developed and include once-weekly exenatide, dulaglutide, albiglutide, semaglutide and miniosmotic pump ITCA650. Some of the attractive qualities of the GLP-1 receptor agonist class include its association with weightloss and potential for cardiovascular benefits. The longer-acting forms have been shown in several studies to produce equal or greater reduction in A1c and weight compared with the standard twice-daily formulation of exenatide. They also result in lower reported incidence of nausea, in the setting of a less frequent injection schedule that would be desirable to many diabetic patients. There are emerging data to suggest patients treated with longer-acting GLP-1 receptor agonists have improved cardiac parameters, some of which are independent of weight and A1c reductions.
