The change of injectable semaglutide into verbally administered portion of drug or other consumable forms shows a significant progress in peptide-located diabetes medicines. This study evaluates the feasibility, pharmacokinetics, and temporary balance of oral semaglutide brought through capsule and liquid formulations in Sprague–Dawley rats. Injectable semaglutide (1 mg/mL) was reformulated using SNAC-located next-release sciences. Both oral formulations illustrated agreeable bioavailability (0.8–0.9%) relative to the injectable form. Pharmacokinetic reasoning told deferred Tmax for the tablet distinguished to the liquid, unpaid to formulation excipients. Stability experiment over 30 days designated maintained potency (95–97%) accompanying gentle opalescence in the liquid expression, inciting plans for enhanced expression plannings. These judgments provide basic evidence advocating future long-term ICH-obedient support studies and expression refinement for numbering spoken GLP-1 agonist development.
