Modulation of the incretin effect has opened up a new strategy in the treatment of diabetes mellitus type 2 (DM2). To date, this physiological mechanism has been boosted in two ways: firstly, by pharmacological inhibition of the enzyme that physiologically degrades glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP4); secondly, through the development of GLP-1 agonists (GLP-1a) that are resistant to the action of DPP-4. ⋯ On the other hand, this higher efficacy also seems to be associated with the higher rate of adverse effects associated with aGLP-1 therapy compared with DPP-4 inhibition. These and other differentiating characteristics of the two drug families will determine the choice of drug therapy in the personalized treatment of hyperglycemia in patients with DM2.

Glucagon-like peptide-1 (GLP-1) receptor agonists are a new group of drugs for the treatment of type 2 diabetes mellitus (DM2). In the present article, we review the available evidence on the efficacy of GLP-1 receptor agonists as glucose-lowering agents, their place in therapeutic algorithms, and the clinical factors associated with a favorable treatment response. Finally, we describe the clinical characteristics of patients who may benefit from these drugs.

Glucagon-like peptide-1 receptor agonists (GLP-1ra) are a new group of drugs with a glucose-lowering action due to their incretin effect. The GLP-1 receptor is expressed in various human tissues, which could be related to the pleiotropic effects of human GLP-1, as well as to the adverse effects described in patients treated with GLP-1ra. ⋯ The most frequent adverse effect is nausea, which usually occurs at the start of treatment and is transient in 20-60% of affected patients. This article also reviews the information available on antibody formation, the potential effect on the thyroid gland, and the controversial association between this group of drugs with pancreatitis and cancer.

The wide ubiquity of GLP-1 receptors in the body has stimulated the search for different extrapancreatic actions of GLP-1 and its receptor agonists. Thus, severe cardioprotective effects directed on myocardial ischaemia and dysfunction as well as diverse antiaterogenic actions have been reported. ⋯ Good results have also been reported in psoriasis. Despite we still need confirmation that these promising effects can be applied to clinical practice, they offer new interesting perspectives for treatment of type 2 diabetes associated complications and give to GLP-1 receptor agonists an even more integral position in diabetes therapy.
