Abstract
The present disclosure provides a composition for submucosal injection including a divalent cation and an oligosaccharide obtained by exposing powdered polysaccharides to irradiation, heat, ultrasound, or ultraviolet radiation. The composition may be provided as a single solution; or the divalent cation and the oligosaccharide may be separately packaged, with the divalent cation being provided in solution form and the oligosaccharide being provided in powder form. The divalent cation may be 0.1-0.5% w/v of Ca, Mg, Fe, Cu, Ba, Zn, or any combination thereof. The oligosaccharide may be 0.5-2% w/v of degraded sodium alginate, degraded xanthan gum, degraded dextran, degraded welan gum, degraded gellan gum, degraded diutan gum, or any combination thereof. When the divalent cation is in contact with the oligosaccharide, viscosity of the composition is greater than 1000 cP, and injection pressure of the composition falls within a range of 2.5-4 kgf.
