Teduglutide- Summary
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- Teduglutide is a GLP-2 (glucagon-like peptide-2) analog with enhanced stability. Unlike GLP-1, GLP-2 specifically acts on the intestinal epithelium to increase intestinal length, villus height, and absorption surface area. FDA-approved as Gattex for short bowel syndrome, it is also being investigated for IBD, leaky gut, and mucosal healing.
- Half-Life
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
- ~2 hours; once-daily dosing due to gut-specific residence
- Admin Route
- Oral, Topical
