Exenatide- Summary
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.
- 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.
- Half-Life
- 8-10 days (exceptionally long; accumulates over weeks)
- ~2.4 hours (Byetta/twice-daily); Bydureon BCISE: weekly via microsphere release

- 5 mcg, titrate to 10 mcg
- Frequency
- Once daily
- Twice daily
- Key Benefits
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
