Purpose Of Review:
Incretin-based therapies are currently being used in the treatment of type 2 diabetes mellitus (T2DM). Apart from glycemic control, these agents have been shown to have multiple extra-pancreatic effects, including their role in blood pressure (BP) regulation. This article will review the origins of incretins, the incretin axis, possible mechanisms of antihypertensive effect of these agents, as well as the recent evidence.
Recent Findings:
Preclinical and clinical studies demonstrate the antihypertensive effects of glucagon-like peptide-1 (GLP-1) and its analogs in patients with T2DM and hypertension. This effect seems to be mediated through vasodilatation as well as modulation of renal sodium handling causing natriuresis, although the exact mechanisms are not fully known.
Summary:
Incretin-based therapies are emerging as a novel class of hypoglycemic agents that display antihypertensive properties. Given the small decreases in BP, it is unlikely that these agents will be used as stand-alone antihypertensive agents, but they may be an attractive option in patients with T2DM and hypertension.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
