MOUNJARO (AUTOINJECTOR) vs WEGOVY HD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It increases glucose-dependent insulin secretion, decreases glucagon secretion, slows gastric emptying, and promotes satiety.
WEGOVY (semaglutide) is a glucagon-like peptide-1 (GLP-1) receptor agonist that increases insulin secretion, decreases glucagon secretion, delays gastric emptying, and promotes satiety.
Subcutaneously once weekly; initial dose 2.5 mg for 4 weeks, then increase to 5 mg for 4 weeks, then 7.5 mg, 10 mg, 12.5 mg, and 15 mg as tolerated; maximum 15 mg weekly.
Subcutaneous injection once weekly. Initiate at 0.25 mg weekly for 4 weeks, then increase to 0.5 mg weekly for 4 weeks, then 1 mg weekly for 4 weeks, then 1.7 mg weekly for 4 weeks, then maintain at 2.4 mg weekly.

Terminal elimination half-life ~5 days (117 hours), supporting once-weekly dosing.
Terminal elimination half-life approximately 165 hours (≈7 days), supporting once-weekly dosing.
Renal: negligible; Fecal: primarily via biliary elimination as intact peptide; total clearance ~0.056 L/h.
Primarily renal elimination of intact peptide; ~47% excreted unchanged in urine, remainder via fecal/biliary routes (≈38%).
