Glucagon-joaloka peptide-1 (GLP-1)ke anhormone ea incretine hlahisoang ke lisele tsa L tsa mala ka lebaka la ho ja lijo. GLP-1 receptor agonists (GLP-1 RAs) e etsisa litlamorao tsa 'mele oa hormone ena ka mekhoa e mengata ea metabolic:
-

-
Ho tsoa ka mpeng butle, ho lelefatsa maikutlo a ho tlala.

-
E ntlafalitse secretion ea insulin le ho fokotseha ha glucagon
-
E susumetsa lisele tsa pancreatic β ho hlahisa insulin ka mokhoa o itšetlehileng ka tsoekere.
-
Hatella secretion ea glucagon, ho ntlafatsa maemo a tsoekere ka ho itima lijo le ka mor'a lijo.
