Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tirzepatide is a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor dual agonist. It binds to and activates both GIP and GLP-1 receptors, leading to increased insulin secretion, decreased glucagon secretion, slowed gastric emptying, and increased satiety, resulting in improved glycemic control and weight loss.
Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It binds to and activates both GIP and GLP-1 receptors, leading to increased insulin secretion in a glucose-dependent manner, decreased glucagon secretion, delayed gastric emptying, and reduced appetite, thereby improving glycemic control and promoting weight loss.
Subcutaneously once weekly; initial dose 2.5 mg for 4 weeks, then increase to 5 mg; if additional glycemic control needed, may increase in 2.5 mg increments after at least 4 weeks on current dose, up to maximum 15 mg once weekly.
Subcutaneous injection once weekly. Initial dose: 2.5 mg for 4 weeks; then increase to 5 mg for at least 4 weeks; further increments of 2.5 mg every 4 weeks as tolerated up to maximum 15 mg once weekly.

Terminal elimination half-life is approximately 5 days (range 4–6 days), supporting once-weekly dosing. Steady state is achieved after 4 weeks of once-weekly administration.
Terminal elimination half-life is approximately 5 days (120 hours), supporting once-weekly subcutaneous dosing. Steady-state concentrations are achieved after 4 weeks of dosing.
Renal elimination of intact peptide (urine) and proteolytic degradation (fecal/biliary). Following subcutaneous administration, approximately 70% of the dose is excreted renally as intact tirzepatide and 30% via feces as metabolites.
Primarily renal and fecal following proteolytic degradation; intact peptide not detected in urine. Approximately 80% of total drug-related material is excreted in urine (mostly inactive metabolites) and 20% in feces (predominantly parent drug).
