Pancreatic Safety of Tirzepatide and Its Effects on Islet Cell Function: A Systematic Review and Meta-Analysis.

Background: Endogenous glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) regulate islet cell function. GLP-1 receptor agonists (GLP-1RAs) have been associated with an elevated risk of acute pancreatitis. Data on the pancreatic safety of tirzepatide (a dual GLP-1 and GIP agonist) and its effects on islet cell function in randomized controlled trials (RCTs) are scarce.

Orforglipron, a novel non-peptide oral daily glucagon-like peptide-1 receptor agonist as an anti-obesity medicine: A systematic review and meta-analysis.

Background: Orforglipron is a novel once-daily oral non-peptide glucagon-like peptide-1 receptor agonist with several recently published randomized controlled trials (RCTs) evaluating its role in diabetes and obesity. No meta-analysis has analyzed the efficacy and safety of orforglipron; this meta-analysis aimed to address this knowledge gap.

Methods: A systematic search was conducted in electronic databases to identify RCTs that included individuals with obesity who were administered orforglipron and compared to either a placebo or an active comparator.
