Together, these findings necessitate further investigations to ascertain whether coordinated inhibition of NMDA receptors in GLP-1 receptor neurons modulates neuronal activity beyond canonical feeding regions, such as the mesolimbic dopaminergic reward pathway

Meanwhile, dual agonists, which target and activate both the GLP-1 (Glucagon-like peptide-1) receptor and the GIP (glucose-dependent insulinotropic polypeptide) receptor, and triple agonists (targeting the GLP-1+GIP+Glucagon receptors) are also showing promise
This has been achieved through techniques such as peptide sequence modification, peptide lipidation, albumin fusion, and Fc fusion

Some newer agents permit less frequent dosingfor example, retatrutide and certain long-acting formulations may allow biweekly or monthly administration
