Liraglutide(CAS 204656-20-2) is a glucagon-like peptide-1 (GLP-1) receptor agonist used clinically to treat type 2 diabetes mellitus.  Liraglutide binds to the same receptors as does the endogenous metabolic hormone GLP-1 that stimulates insulin secretion. Liraglutide is an injectable drug for the treatment of type 2 diabetes, also can be used to treat obesity in adults with some related comorbidity. Liraglutide activated AMPK/SREBP1 pathway in oxLDL-stimulated Raw264.7 cells.

Recently, the European Medicines Agency (EMEA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending to grant a marketing authorization for liraglutide for the treatment of type 2 diabetes mellitus. Liraglutide is the first human glucagon-like peptide-1 (GLP-1) analog, based on the structure of native GLP-1, with pharmacokinetic properties suitable for once-daily dosing. In the phase III Liraglutide Effect and Action in Diabetes (LEAD) program, liraglutide has been shown to lower glycated hemoglobin to the same extent or more than other antidiabetic drugs including insulin. Liraglutide determines favorable changes in the global cardiovascular risk profile because its use is associated with weight loss, blood pressure reduction, as well as improvements of several cardiovascular risk biomarkers. Liraglutide is generally well tolerated, the most frequently reported adverse effect is transient nausea, and it does not seems to have significant interactions with medications commonly used for cardiovascular prevention. This article reviews, for the practicing cardiologist, the results of the LEAD program and explores liraglutide potentials for cardiovascular prevention in type 2 diabetes mellitus.

Liraglutide is a novel glucagon-like peptide-1 (GLP-1) receptor agonist with 97% amino acid sequence identity to native GLP-1. An amino acid substitution and fatty acid side chain enable a more protracted pharmacokinetic profile of over 24 hours. These modifications make liraglutide suitable for once-daily dosing. Liraglutide use exploits the incretin effect to glucose-dependently stimulate insulin secretion. The LEAD (Liraglutide Effect and Action Diabetes) program evaluated the safety and efficacy of liraglutide and demonstrated an improved level of glycemic control relative to currently used oral antidiabetic drugs, including other GLP-1-based therapies. In these trials, liraglutide was shown to enable many patients to achieve hemoglobin A1c (HbA1c) targets and to improve several morbidities commonly associated with type 2 diabetes; liraglutide induced weight loss, reduced systolic blood pressure and improved beta-cell function. Liraglutide was well tolerated, although an increased incidence of mild nausea was observed. Since liraglutide mimics the glucose-sensitive action of native GLP-1, it does not induce hypoglycemia. Liraglutide offers an interesting alternative therapy to control blood glucose levels in patients with type 2 diabetes, who commonly present with hypertension and overweight. It is expected to be approved by the U.S. Food and Drug Administration and the European Medicines Agency in Europe for use in 2009.

The incretin hormones are intestinal peptides that enhance insulin secretion following ingestion of nutrients. Liraglutide is a glucagon-like peptide-1 receptor analogue, which is obtained by derivatising glucagon-like peptide-1 with a fatty acid, providing a compound with pharmacokinetic properties that are suitable for once-daily dosing. Liraglutide has demonstrated lasting improvement of HbA(1c )levels, weight reduction and improved beta-cell function in patients with Type 2 diabetes mellitus. Liraglutide is well tolerated; the adverse events that are most frequently reported being transient nausea and diarrhoea. This article reviews the mechanisms of action and efficacy of liraglutide for the treatment of Type 2 diabetes mellitus. This agent is presently in Phase III clinical development.
