The mechanism of how GIPR and GLP-1R agonism synergizes to enhance body weight loss are not known, but a series of experimental results indicates that GIP acts on the GIP receptor in the brain to decrease body weight via inhibition of food intake (156, 179, 187)
But interestingly, studies with rodents have shown that dopamine levels dont increase if they are given a GLP-1 medication before alcohol consumption
While prior large-scale studies earlier in 2024 did not find an association between GLP-1 receptor agonists and retinopathy, this recent case series suggests that a subset of patients may be vulnerable to optic nerve damage and other vision complications [1,2]
What are the potential risks and complications when semaglutide (Glucagon-like peptide-1 (GLP-1) receptor agonist) is administered via intramuscular (IM) injection instead of subcutaneous (SUBQ) injection?
Because the arginate form maintains stability longer in circulation, it provides more consistent systemic exposure
