Summary
Exenatide is a GLP-1 receptor agonist derived from the Gila monster lizard peptide exendin-4, with 53% homology to human GLP-1 and natural resistance to DPP-4 degradation. Available as twice-daily (Byetta) or once-weekly (Bydureon) formulation, it is also being studied for Parkinson's disease neuroprotection.
Oxytocin is a 9-amino acid neuropeptide produced in the hypothalamus with diverse roles in social bonding, trust, stress reduction, and sexual function. Exogenous administration is used therapeutically to improve social cognition, reduce anxiety, and enhance intimacy.
Half-Life
~2.4 hours (Byetta/twice-daily); Bydureon BCISE: weekly via microsphere release
~3–5 minutes (IV); ~30–60 minutes (intranasal, CNS effects persist longer)
