Potentiation of weight reduction with GLP-1 receptor agonists

Abstract

Glucagon-like peptide-1 receptor agonists are the antidiabetic agents that are associated with the greatest weight loss beyond a marked reduction in glycated haemoglobin. Weight loss results from a reduction in appetite through a predominant central effect combined with a peripheral effect. Liraglutide and semaglutide are developed for the treatment of obesity, independently of type 2 diabetes. Three approaches may be considered to potentiate weight loss: an increase of the drug dosage because of the demonstration of a dose-response, an add-on therapy with a sodium-glucose cotransporter type 2 inhibitor as this agent exerts a complementary action through urinary calorie loss (glucosuria) or a combination of the effects of two incretin hormones (GLP-1 and GIP), as the potent dual agonist tirzepatide currently in development.

Les agonistes des récepteurs du glucagon-like peptide-1 (GLP-1) sont les agents antidiabétiques qui, outre une baisse importante du taux d’hémoglobine glyquée, offrent la perte pondérale la plus marquée, en augmentant la satiété par un effet central, prédominant et périphérique. Le liraglutide et le sémaglutide sont développés pour le traitement de l’obésité, indépendamment de la présence d’un diabète de type 2. Trois approches sont possibles pour potentialiser la perte de poids: augmenter la posologie, compte tenu de l’existence d’une relation dose-réponse, ajouter un inhibiteur des sodium-glucose cotransporteurs 2 qui exerce un effet complémentaire…
