This offers several potential benefits: Avoids first-pass metabolism : Unlike swallowed medications that must pass through the liver, sublingual absorption delivers drugs directly to the bloodstream Bypasses stomach acid : GLP-1 peptides are degraded by digestive enzymes, so avoiding the stomach could improve stability Rich vascular network : The area under the tongue has extensive blood vessels that allow rapid absorption However, research on peptide delivery through oral mucosa reveals significant challenges: Peptides like semaglutide and tirzepatide have molecular weights around 4000 Da (compounds above 500 Da generally show poor permeability) Salivary and mucosal proteases degrade peptides before they can cross the epithelial barrier Continuous saliva production dilutes and washes away the medication Studies with insulin showed only 1-2% bioavailability via buccal/sublingual routes without absorption enhancers The key question: Do compounded ODT formulations overcome these barriers

Later, dipeptidyl peptidase-4 (DPP-4) was reported to rapidly remove the N-terminal diamino acid peptide of GLP-1 by recognizing alanine and proline at the penultimate position [4]

In comparison to placebos, these adverse effects were reported more frequently in several trials clinically, although not always markedly different from active comparator groups [77]

Further, experimental data suggest that the pro-survival action of GLP-1RAs may also be mediated by the Akt-dependent stimulation of the mTORC1/S6K1 pathway, the activation of which is dependent upon the IGF-1R, as observed in rodent islet cells (44)
