By pre-treating rats with the non-specific cholinergic receptor antagonist atropine as well as the specific M3 cholinergic receptor antagonist 4-DAMP and performing vagotomy, the researchers found that atropine and 4-DAMP significantly reduced metformin-induced GLP-1 secretion, whereas vagotomy had no effect on metformin-induced GLP-1 secretion
Retatrutide has attracted interest because of its activity across GLP-1, GIP and glucagon receptor pathways
