Glypressin Injection consists of a powder and solvent for solution for injection. The white, freeze-dried powder contains terlipressin acetate. Glypressin Injection is used in the treatment of bleeding oesophageal varices. Bleeding oesophageal varices are enlarged blood vessels that form in the stomach or oesophagus as a complication of liver disease. They may burst and bleed and this is a serious and life-threatening condition. When injected into the bloodstream, the active ingredient, terlipressin acetate is broken down to release a substance called lysine vasopressin. This acts on the walls of the blood vessels, causing them to narrow and restrict the blood flow to the affected veins so that bleeding is reduced
